Roderick W. Smith | e09ef88 | 2013-07-08 22:56:00 -0400 | [diff] [blame] | 6 | 0.8.7 (7/8/2013): |
srs5694 | f5dfbfa | 2013-02-14 20:47:14 -0500 | [diff] [blame] | 7 | ----------------- |
| 8 | |
Roderick W. Smith | e09ef88 | 2013-07-08 22:56:00 -0400 | [diff] [blame] | 9 | - Modified Mac version so that it can work on /dev/rdisk* devices as well |
| 10 | as /dev/disk* devices. The result is that, when using the /dev/rdisk* |
| 11 | devices, the partition table can sometimes be re-read without removing |
| 12 | the disk or rebooting. |
| 13 | |
| 14 | - Added "-a" option to cgdisk to use a ">" symbol to the left of the |
| 15 | selected partition rather than ncurses highlighting. |
| 16 | |
Roderick W. Smith | 1eea9b0 | 2013-07-06 22:52:58 -0400 | [diff] [blame] | 17 | - Modified "converting MBR to GPT" message to clarify that the conversion |
| 18 | is being held in memory, since some people have mistakenly assumed that a |
| 19 | "gdisk -l" operation will change an MBR disk to a GPT disk without |
| 20 | prompting. |
| 21 | |
| 22 | - Added partition type code for freedesktop.org's proposed $BOOT partition |
| 23 | (bc13c2ff-59e6-4262-a352-b275fd6f7172; GPT fdisk type code EA00) |
| 24 | |
srs5694 | f5dfbfa | 2013-02-14 20:47:14 -0500 | [diff] [blame] | 25 | - Adjusted alignment code when using -n or -N in sgdisk to keep the |
| 26 | requested partition size (if specified using +###{MGT} terminology) |
| 27 | as the requested value rather than relative to the requested start |
| 28 | point. This gives you the requested partition size rather than be |
| 29 | slightly smaller if sgdisk needs to adjust the start point up a bit and |
| 30 | it prevents gaps from appearing between partitions if several are created |
| 31 | in succession using automatic placement of the start point. |
| 32 | |
| 33 | - Fixed small bugs in gdisk_test.sh script. |
| 34 | |
| 35 | - Removed stray debug message that would appear when reading MBR disks. |
| 36 | |
Roderick W. Smith | 1eea9b0 | 2013-07-06 22:52:58 -0400 | [diff] [blame] | 37 | - Added partition type code for Intel Rapid Start partition (GUID |
| 38 | D3BFE2DE-3DAF-11DF-BA40-E3A556D89593, code 8400), used by systems that |
srs5694 | f5dfbfa | 2013-02-14 20:47:14 -0500 | [diff] [blame] | 39 | implement Intel's Rapid Start technology. See |

srs5694 | f5dfbfa | 2013-02-14 20:47:14 -0500 | [diff] [blame] | 42 | |
| 43 | - Added partition type code for Haiku BFS (GUID |
| 44 | 42465331-3BA3-10F1-802A-4861696B7521; code EB00). |
| 45 | |
srs5694 | 0741fa2 | 2013-01-09 12:55:40 -0500 | [diff] [blame] | 46 | 0.8.6 (1/9/2013): |
| 47 | ----------------- |
| 48 | |
| 49 | - Fixed a bug that could cause sgdisk to crash when passing a partition |
| 50 | number of 0 to the -t option. |
| 51 | |
| 52 | - Added support for building under Solaris. |
srs5694 | d8eed46 | 2012-12-15 01:55:21 -0500 | [diff] [blame] | 53 | |
| 54 | - Added a new check to the verification code. |
| 55 | |
| 56 | - Added partition type code for Sony system partition |
| 57 | (F4019732-066E-4E12-8273-346C5641494F). I'm not entirely clear what this |
| 58 | is used for, but it's appearing on some new Sony computers. |
| 59 | |
| 60 | - Tweaked hybrid MBR creation options to fix a problem that caused the main |
| 61 | 0xEE MBR partition to NOT be created if the user told gdisk to NOT place |
| 62 | it at the start of the disk AND IF fewer than three partitions are |
| 63 | hybridize AND IF the user opted to create a second protective partition. |
| 64 | |
| 65 | - Changed default build options for Mac OS X to *NOT* use libicu, |
| 66 | since it seems to have broken somewhere along the line. It still |
| 67 | works on Linux, though. |
| 68 | |
| 69 | - Added partition type codes for VMWare ESX (FB00, FB01, and FC00). |
| 70 | |
srs5694 | 4307ef2 | 2012-05-30 12:30:48 -0400 | [diff] [blame] | 71 | 0.8.5 (5/30/2012): |
srs5694 | fa3868e | 2012-03-28 01:45:57 -0400 | [diff] [blame] | 72 | ------------------ |
| 73 | |
srs5694 | 4307ef2 | 2012-05-30 12:30:48 -0400 | [diff] [blame] | 74 | - Changed code that writes the partition table so that a disk sync |
| 75 | operation occurs even if one or more write operations failed (but not if |
| 76 | they all failed). This is intended to work around a bug that a user |
| 77 | reported on a Windows system on which the write of the protective MBR |
| 78 | failed, although everything else worked. (I suspect anti-virus software |
| 79 | may have been blocking write access to the MBR.) |
| 80 | |
srs5694 | fa3868e | 2012-03-28 01:45:57 -0400 | [diff] [blame] | 81 | - Added type codes for Midnight BSD (0xA580 - 0xA585). I used these codes |
| 82 | because Midnight BSD uses the same 0xA5 type code as FreeBSD on MBR |
| 83 | disks, so I'm starting Midnight BSD's numbering halfway through the |
| 84 | 0xA5## range. |
| 85 | |
srs5694 | a6297b8 | 2012-03-25 16:13:16 -0400 | [diff] [blame] | 86 | 0.8.4 (3/25/2012): |
| 87 | ------------------ |
| 88 | |
| 89 | - REALLY fixed Ctrl+D problems! Now gdisk terminates upon receiving a |
| 90 | Ctrl+D. In all previous versions, it could lock itself into a CPU-hogging |
| 91 | loop if launched via "sudo" from a terminal window that was then closed |
| 92 | or if Ctrl+D was pressed at certain input prompts (for a partition name |
| 93 | or sector number, for instance). |
| 94 | |
srs5694 | 3488294 | 2012-03-23 12:49:15 -0400 | [diff] [blame] | 95 | 0.8.3 (3/23/2012): |
srs5694 | e842bc1 | 2012-02-03 11:27:05 -0500 | [diff] [blame] | 96 | ------------------ |
| 97 | |
srs5694 | 3488294 | 2012-03-23 12:49:15 -0400 | [diff] [blame] | 98 | - Fixed compilation problem on GCC 4.7. |
| 99 | |
| 100 | - Improved handling of Ctrl+D on some systems. |
| 101 | |
| 102 | - Added disk's name to message stating that a disk write was successful. |
| 103 | |
| 104 | - Fixed bug that caused creation of >2TiB partitions on 32-bit systems to |
| 105 | be truncated in sgdisk. |
srs5694 | e842bc1 | 2012-02-03 11:27:05 -0500 | [diff] [blame] | 106 | |
| 107 | 0.8.2 (1/22/2012): |
srs5694 | dcebe57 | 2012-01-22 15:03:42 -0500 | [diff] [blame] | 108 | ------------------ |
srs5694 | 0541b56 | 2011-12-18 16:35:25 -0500 | [diff] [blame] | 109 | |
srs5694 | 706e512 | 2012-01-21 13:47:24 -0500 | [diff] [blame] | 110 | - Adjusted the code to support a number of partitions that's not a multiple |
| 111 | of the number of partition table entries that fits in a sector (normally |
| 112 | 4 per sector). The program still rounds up, when necessary, when resizing |
| 113 | the partition table manually, but not when loading a partition table that |
| 114 | contains a peculiar number of partitions. This helps prevent spurious |
| 115 | error messages about CRC problems when loading some Solaris partition |
| 116 | tables. |
| 117 | |
srs5694 | e69e680 | 2012-01-20 22:37:12 -0500 | [diff] [blame] | 118 | - Fixed bugs relating to the handling of empty partitions; Solaris's ZFS |
| 119 | tools create weird empty partitions that are legal but that gdisk wasn't |
| 120 | handling properly. (Specifically, they sometimes have non-zero end |
| 121 | points; gdisk assumed empty partitions had end points of 0.) |
| 122 | |
srs5694 | 0541b56 | 2011-12-18 16:35:25 -0500 | [diff] [blame] | 123 | - Fixed a bug that caused an infinite loop of input prompts if the user |
| 124 | pressed Ctrl+D. |
| 125 | |
| 126 | - Changed gdisk's first-sector input operation to specify a sector number |
| 127 | that's properly aligned as the default value. This eliminates the need |
| 128 | to alter that value and notify the user of the change when the user |
| 129 | hits "Enter" for the default value as the first partition on an empty |
| 130 | disk (as well as in some other situations). |
| 131 | |
srs5694 | 23d8d54 | 2011-10-01 18:40:10 -0400 | [diff] [blame] | 132 | 0.8.1 (10/1/2011): |
srs5694 | d1b11e8 | 2011-09-18 21:12:28 -0400 | [diff] [blame] | 133 | ------------------ |
| 134 | |
srs5694 | 23d8d54 | 2011-10-01 18:40:10 -0400 | [diff] [blame] | 135 | - Fixed bug that could cause FixParts to keep a partition's assignment |
| 136 | as logical when FixPart could not actually do so. This could happen |
| 137 | when there are no gaps between two logical partitions. Some partitioning |
| 138 | tools can create such configurations, but FixParts can't. Such |
| 139 | configurations are extremely rare. I've only encountered them when |
| 140 | logical partitions are out of order. |
| 141 | |
| 142 | - Added code to detect infinite loops of logical partitions when reading |
| 143 | MBR data. When detected, the program now stops reading after the first |
| 144 | loop, so no duplicates appear in the partition list. |
| 145 | |
| 146 | - Fixed bug in partition overlap detection in MBR code. |
| 147 | |
srs5694 | d1b11e8 | 2011-09-18 21:12:28 -0400 | [diff] [blame] | 148 | - Changed GPT reading code to use the size encoded in GPT headers to |
| 149 | determine how much of the header to use in computing a CRC, with the |
| 150 | restriction that the size be equal to or less than the disk's sector |
| 151 | size. This should work around problems with libefi in ZFS, which sets the |
srs5694 | 23d8d54 | 2011-10-01 18:40:10 -0400 | [diff] [blame] | 152 | header size to 512 rather than the more common 92. A caveat: If the |
| 153 | disk's sector size is larger than the GPTHeader data structure size (512 |
| 154 | bytes), then the rest of the sector's contents are ignored and replaced |
| 155 | with 0 values. This could produce false positives on CRC checks on disks |
| 156 | with over-512-byte sector sizes if the header sector is padded with |
| 157 | something other than 0 values. |
srs5694 | d1b11e8 | 2011-09-18 21:12:28 -0400 | [diff] [blame] | 158 | |
| 159 | - Fixed bug in new (as of 0.8.0) check that main and backup partition |
| 160 | tables are identical on big-endian (PowerPC, etc.) hardware. |
| 161 | |
srs5694 | a17fe69 | 2011-09-10 20:30:20 -0400 | [diff] [blame] | 162 | 0.8.0 (9/10/2011): |
| 163 | ------------------ |
| 164 | |
| 165 | - Added new return option for sgdisk: 8, which means that a replication |
| 166 | operation (-R or --replicate) failed. Note that other operations on |
| 167 | the same command line might still have succeeded. |
| 168 | |
| 169 | - Added gdisk_test.sh shell script, contributed by Guillaume Delacour. |
| 170 | This script tests some common gdisk and sgdisk operations to be sure |
| 171 | they're working correctly. |
| 172 | |
| 173 | - Enable sgdisk's -l (--load-backup) and -o (--clear) options to work |
| 174 | even on disks that are damaged. Most other options will still be ignored, |
| 175 | though, so if you suspect a disk may be bad and want to use one of these |
| 176 | options, you should do so on a line by itself, followed by a separate |
| 177 | command to perform other actions (such as adding new partitions). |
| 178 | |
| 179 | - Added check for mis-matched primary and backup partition tables. |
| 180 | A mismatch is reported as a CRC error. |
| 181 | |
| 182 | - Added Apple Core Storage partition type code (hex code AF05, GUID |
| 183 | 53746F72-6167-11AA-AA11-00306543ECAC). |
| 184 | |
| 185 | - Added cgdisk program to the family. This program is a rough workalike |
| 186 | to cfdisk, much as gdisk is a rough workalike to fdisk. See the cgdisk |
| 187 | man page or http://www.rodsbooks.com/gdisk/cgdisk-walkthrough.html for |
| 188 | details about its operation. |
| 189 | |
| 190 | - Fixed bug that caused CHS end point for protective MBR to be set to |
| 191 | 0xfeffff rather than the spec-mandated 0xffffff on disks over ~8GB. This |
| 192 | is a very minor bug, since not much cares about this, and most other GPT |
| 193 | tools get it wrong in the same way, too. |
| 194 | |
srs5694 | 00b6d7a | 2011-06-26 22:40:06 -0400 | [diff] [blame] | 195 | 0.7.2 (6/26/2011): |
srs5694 | 6aae2a9 | 2011-06-10 01:16:51 -0400 | [diff] [blame] | 196 | ------------------ |
| 197 | |
srs5694 | 00b6d7a | 2011-06-26 22:40:06 -0400 | [diff] [blame] | 198 | - The Windows version now (finally!) generates proper GUIDs rather than a |
| 199 | purely random number. This fixes a bug that caused Windows 7 to crash |
| 200 | when converting a disk from MBR format (but, oddly, not when creating a |
| 201 | fresh partition table or doing various other things). |
| 202 | |
| 203 | - Added a warning when an MBR partition is discarded because it's too |
| 204 | big for the disk. |
| 205 | |
| 206 | - Changed warning to Windows users about the dangers of converting to GPT |
| 207 | so that it appears only on disks that aren't already in GPT form. |
| 208 | |
| 209 | - Fixed bug that caused bogus "3" values to pad the ends of partition names |
| 210 | on some disks (particularly those created by Microsoft's disk |
| 211 | partitioning tools). |
| 212 | |
| 213 | - Made compilation without Unicode support possible (see README file) |
| 214 | |
| 215 | - Made default filesystem type code OS-dependent (based on the compilation |
| 216 | platform). |
| 217 | |
| 218 | - Added new Linux-only filesystem partition type GUID code, |
| 219 | 0FC63DAF-8483-4772-8E79-3D69D8477DE4 (8300 entry code). Also changed name |
| 220 | of the EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (0700 entry code) to |
| 221 | "Microsoft basic data"). |
| 222 | |
srs5694 | 6aae2a9 | 2011-06-10 01:16:51 -0400 | [diff] [blame] | 223 | - Fixed a bug that caused an incorrect code to be set for active/bootable |
| 224 | partitions when generating a hybrid MBR. |
| 225 | |
| 226 | - Enable entry of hex codes that begin with "0x" for both GPT and MBR |
| 227 | partitions. |
| 228 | |
| 229 | - Fixed bug that caused the boot loader code to be lost when creating a |
| 230 | hybrid MBR. |
| 231 | |
| 232 | - Fixed bug in sector input code that could produce improper values |
| 233 | if the user inputs ridiculously large "+" values. |
| 234 | |
srs5694 | 699941e | 2011-03-21 21:33:57 -0400 | [diff] [blame] | 235 | 0.7.1 (3/21/2011): |
| 236 | ------------------ |
| 237 | |
| 238 | - Added support for proper UTF-16LE partition names rather than the |
| 239 | "shortcut" that properly encoded only ASCII names. This support works |
| 240 | only in Linux, FreeBSD, and OS X, though, at least for the moment. |
| 241 | Although it's possible to compile this support into Windows when using |
| 242 | Visual C++, it doesn't seem to work properly. Since using this feature |
| 243 | would require distributing the ICU libraries with the Windows binary, |
| 244 | thus bloating the binary package's size to no effect, I've disabled it in |
| 245 | my standard Windows build, at least for now. |
| 246 | |
| 247 | - Added check to fixparts to keep it from operating on devices that |
| 248 | lack an existing MBR signature. (In 0.7.0, it could write an empty |
| 249 | MBR data structure to a device on which it was mistakenly launched.) |
srs5694 | d3ba7a6 | 2011-03-13 11:51:34 -0400 | [diff] [blame] | 250 | |
srs5694 | 815fb65 | 2011-03-18 12:35:56 -0400 | [diff] [blame] | 251 | - Fixed bug that caused the protective MBR to not be written when |
| 252 | restoring a backup of the GPT data. |
| 253 | |
srs5694 | 5a60853 | 2011-03-17 13:53:01 -0400 | [diff] [blame] | 254 | - Fixed bug that caused second protective MBR partition, when created |
| 255 | as part of a hybrid MBR, to always be of type 0xEE, even when the |
| 256 | user specified something else. |
| 257 | |
srs5694 | c2f6e0c | 2011-03-16 02:42:33 -0400 | [diff] [blame] | 258 | - Integrated a number of code cleanups contributed by Florian Zumbiehl. |
srs5694 | d3ba7a6 | 2011-03-13 11:51:34 -0400 | [diff] [blame] | 259 | |
srs5694 | bf8950c | 2011-03-12 01:23:12 -0500 | [diff] [blame] | 260 | 0.7.0 (3/11/2011): |
srs5694 | 64cbd17 | 2011-03-01 22:03:54 -0500 | [diff] [blame] | 261 | ------------------ |
| 262 | |
srs5694 | bf8950c | 2011-03-12 01:23:12 -0500 | [diff] [blame] | 263 | - Fixed bug that caused some types of logical partitions to be misread. |
| 264 | |
| 265 | - Created FixParts program, to fix problems on MBR-partitioned disks. |
| 266 | Although this program is part of the GPT fdisk family, it is NOT used on |
| 267 | GPT disks. |
| 268 | |
| 269 | - Completely redid the GPT-to-MBR code, used both for converting to MBR |
| 270 | form and for creating hybrid MBRs. |
| 271 | |
| 272 | - Fixed a bug that caused gdisk to "forget" some partitions if there were |
| 273 | numbering gaps when a conversion to MBR was aborted. |
| 274 | |
| 275 | - Improved CHS value creation on small (<~8GB) disks for protective MBR |
| 276 | and when creating hybrid MBRs or converting to MBR format. Linux-only, |
| 277 | for the moment; other platforms still produce bad CHS values on sub-~8GB |
| 278 | disks (but few OSes care these days). |
| 279 | |
srs5694 | 64cbd17 | 2011-03-01 22:03:54 -0500 | [diff] [blame] | 280 | - Enhanced disk replication features ('u' on the experts' menu in gdisk; -R |
| 281 | or --replicate in sgdisk). It's now possible to replicate the partition |
| 282 | table from a larger to a smaller disk, so long as all the partitions fit |
| 283 | on the smaller disk. In sgdisk, the secondary GPT data are moved |
| 284 | automatically if disk sizes don't match. In gdisk, the secondary GPT data |
| 285 | are moved automatically if the target disk is smaller than the source |
| 286 | disk; if the target disk is larger than the source disk, the user is |
| 287 | given the option of making this adjustment. |
| 288 | |
| 289 | - Fixed --load-backup (-l) option to sgdisk, which was broken. |
| 290 | |
| 291 | - Changed largest drive that's not given a minimum 4 KiB alignment even |
| 292 | when smaller alignment is detected on the disk to 300 GB. |
| 293 | |
srs5694 | bf8950c | 2011-03-12 01:23:12 -0500 | [diff] [blame] | 294 | - Fixed bug that prevented aborting a partition table backup ('u' on the |
srs5694 | 64cbd17 | 2011-03-01 22:03:54 -0500 | [diff] [blame] | 295 | experts' menu) by hitting the Enter key for the device filename. |
| 296 | |
srs5694 | bf8950c | 2011-03-12 01:23:12 -0500 | [diff] [blame] | 297 | - Implemented a number of code cleanups provided by Florian Zumbiehl. |
srs5694 | 64cbd17 | 2011-03-01 22:03:54 -0500 | [diff] [blame] | 298 | |
srs5694 | df9d363 | 2011-01-08 18:33:24 -0500 | [diff] [blame] | 299 | 0.6.14 (1/8/2011): |
| 300 | ------------------ |
| 301 | |
| 302 | - Made small change to the way the start sector is interpreted if you use a |
| 303 | "+" specification, as in "+2G" to locate a partition 2 GiB into the |
| 304 | default range. This change makes adjustments for sector alignment less |
| 305 | likely. |
| 306 | |
| 307 | - Modified sgdisk's -n (--new) option to work with relative start and end |
| 308 | values (which the man page incorrectly stated it already did). Values of |
| 309 | 0 for the start and end sectors refer to the first and last available |
| 310 | sectors in the largest free block, and a partition number of 0 refers to |
| 311 | the first available partition. |
| 312 | |
| 313 | - Added ChromeOS GUID values to list of recognized partition type GUIDs. |
| 314 | 7F00 = ChromeOS kernel, 7501 = ChromeOS root, 7502 = ChromeOS reserved. |
| 315 | Untested on actual ChromeOS system. |
| 316 | |
| 317 | - Tweaked APM detection to look for APM signature even if an MBR |
| 318 | signature has already been found. Helps in diagnosis of cases |
| 319 | in which an MBR has overwritten an APM disk. |

| 322 | -------------------- |
| 323 | |
| 324 | - Added notification about nonexistent partitions to hybrid MBR creation |
| 325 | in gdisk. |
| 326 | |
| 327 | - Fixed bug in GPT-to-MBR conversion that could sometimes enable creation |
| 328 | of an extended partition that overlaps a preceding partition. |
| 329 | |
| 330 | - Fixed bug in GPT-to-MBR conversion that prevented creation of an MBR |
| 331 | table with logical partitions if there were four or fewer partitions. |
| 332 | |
srs5694 | 0873e9d | 2010-10-07 13:00:45 -0400 | [diff] [blame] | 333 | 0.6.12 (10/7/2010): |
| 334 | ------------------- |
| 335 | |
| 336 | - Adjusted alignment code to use 1 MiB alignment by default for drives with |
| 337 | other than 512-byte sector sizes. (Previous versions increased this -- |
| 338 | for instance, to 4 MiB for drives with 2048-byte logical sector size.) |
| 339 | |
| 340 | - Entry of non-hexadecimal value for partition type code now causes |
| 341 | re-prompting for a new value, fixing a recently-introduced minor bug. |
| 342 | |
| 343 | - Fixed bug in sector entry using K/M/G/T/P suffixes on disks with |
| 344 | other-than-512-byte sector numbers. |
| 345 | |
| 346 | - Added "P" (PiB, pebibyte) suffix to suffixes accepted in entering |
| 347 | partition sizes. |
| 348 | |
| 349 | - Fixed bug that caused sgdisk to segfault if fed the (invalid) |
| 350 | "-A show" parameter. Now it terminates with a complaint about an invalid |
| 351 | partition number 0. |
| 352 | |
| 353 | - Removed warning when running on big-endian hardware, since this |
| 354 | support has been present for quite a while with no bug reports. |
| 355 | |
srs5694 | ab4b043 | 2010-09-25 20:39:52 -0400 | [diff] [blame] | 356 | 0.6.11 (9/25/2010): |
| 357 | ------------------- |
| 358 | |
| 359 | - Added -F (--first-aligned-in-largest) option to sgdisk. This option is a |
| 360 | variant on -f (--first-in-largest); it returns the number of the first |
| 361 | sector that will be used in the largest free area, given the current |
| 362 | alignment value (set via -a/--set-alignment). |
srs5694 | 659eaf1 | 2010-08-23 11:26:12 -0400 | [diff] [blame] | 363 | |
srs5694 | 5a08175 | 2010-09-24 20:39:41 -0400 | [diff] [blame] | 364 | - Streamlined GUID code entry in gdisk; it no longer offers the option |
| 365 | to enter GUIDs in separate segments. |
srs5694 | 82f3f0b | 2010-09-22 10:50:24 -0400 | [diff] [blame] | 366 | |
srs5694 | 327129e | 2010-09-22 01:07:31 -0400 | [diff] [blame] | 367 | - The -t option to sgdisk now accepts GUID values as well as the |
| 368 | sgdisk/gdisk-specific two-byte hex codes. |
| 369 | |
| 370 | - Added check that the protective 0xEE MBR partition begins on sector 1 |
| 371 | to the verify function. If it doesn't, a warning message is displayed, |
| 372 | but it doesn't count as an error. |
| 373 | |
| 374 | - Added check for overlapping MBR partitions to verify function (gdisk "v" |
| 375 | function on all menus; sgdisk -v/--verify function). Also warns about |
| 376 | multiple MBR 0xEE partitions (causes problems in some OSes). |
| 377 | |
| 378 | - Added check to GPT-to-MBR and hybrid MBR creation options to prevent |
| 379 | creation of disks with duplicate partitions. When told to create a disk |
| 380 | with duplicates, sgdisk now aborts with the error message "Problem |
| 381 | creating MBR!" When attempting to create a hybrid MBR with duplicates, |
| 382 | gdisk silently drops duplicate partitions, leaving fewer than requested. |
| 383 | Creating duplicates should not be possible in sgdisk when converting to |
| 384 | MBR form. |

srs5694 | f9312b0 | 2010-07-06 15:39:51 -0400 | [diff] [blame] | 388 | |
srs5694 | 9ddc14b | 2010-08-22 22:44:42 -0400 | [diff] [blame] | 389 | - Enable disk-wipe (-z and -Z) and verification (-v) operations in |
| 390 | sgdisk even if the disk is badly damaged. |
| 391 | |
| 392 | - Added support for setting attributes in sgdisk (-A/--attributes option) |
| 393 | in sgdisk. |
| 394 | |
| 395 | - Fixed bug that created backwards attribute field values (bit #2 was |
| 396 | entered as bit #61, etc.). |
| 397 | |
| 398 | - Fixed bug that caused creation of hybrid MBR to wipe out the MBR's boot |
| 399 | code. |
| 400 | |
| 401 | - Added ability to save partition table from one device to another (gdisk: |
| 402 | 'u' on experts' menu; sgdisk: -R or --replicate option). |
| 403 | |
| 404 | - Fixed inaccessible -C/--recompute-chs option in sgdisk. |

| 407 | ------------------ |
| 408 | |
| 409 | - Fixed minor error in sgdisk man page (--largest-new option requires |
| 410 | a partition number). |
| 411 | |
| 412 | - Fixed major bug in hybrid MBR creation, which caused incorrect |
| 413 | protective partition end point settings and occasionally other |
| 414 | problems. |
| 415 | |
srs5694 | 0e197dc | 2010-05-23 13:06:10 -0400 | [diff] [blame] | 416 | 0.6.8 (5/23/2010): |
| 417 | ------------------ |
| 418 | |
srs5694 | 61768bc | 2010-07-04 01:54:00 -0400 | [diff] [blame] | 419 | - Added tests to see if the file to be opened is a directory, character |
| 420 | device, FIFO, or socket; program now terminates if any of these |
| 421 | conditions is met. (Linux/FreeBSD/OS X only.) Thanks to Justin Maggard |
| 422 | for this patch. |
srs5694 | 0e197dc | 2010-05-23 13:06:10 -0400 | [diff] [blame] | 423 | |
| 424 | - Added 'f' option on gdisk's experts' menu (-G/--randomize-guids in |
| 425 | sgdisk). This option randomizes the disk's GUID and all partitions' |
| 426 | GUIDs. Intended for use after cloning a disk with a utility that copies |
| 427 | the GUIDs intact (such as a raw dd copy) if you want each disk copy to |
| 428 | have its own set of GUIDs. |
| 429 | |
| 430 | - Added -u/--partition-guid and -U/--disk-guid options to sgdisk. These are |
| 431 | the equivalents of the 'g' and 'c' options, respectively, on the gdisk |
| 432 | experts' menu: They enable adjusting an individual partition's GUID or a |
| 433 | disk's GUID. The GUID may be either a fully specified GUID value or 'R' |
| 434 | or 'r' to set a random GUID value. |
| 435 | |
| 436 | - Fixed compile problem for FreeBSD (its math library lacks a log2() |
| 437 | function). Also created separate Makefile.freebsd with a couple of |
| 438 | FreeBSD-specific options. |
| 439 | |
| 440 | - Added -N (--largest-new) command to sgdisk. This command creates a single |
| 441 | partition that fills the largest single unpartitioned block of space on |
| 442 | the disk. |
| 443 | |
| 444 | - Fixed sgdisk man page error: the --change-name option was incorrectly |
| 445 | listed as --change. |
| 446 | |
| 447 | - Added 'h' option to gdisk experts' menu (-C or --recompute-chs in sgdisk) |
| 448 | to recompute all protective/hybrid MBR CHS values. This option is |
| 449 | intended to work around a bug in at least one BIOS that prevents the |
| 450 | computer from booting when the GPT-mandated (but technically illegal) |
| 451 | 0xFFFFFF CHS value is used as the end point for a protective MBR. The |
| 452 | recomputed values will be legal (e.g., 0xFEFFFF instead of 0xFFFFFF), |
| 453 | but incorrect in GPT terms, and will therefore enable at least one |
| 454 | BIOS to boot with a GPT disk. See http://www.rodsbooks.com/gdisk/bios.html |
| 455 | for all I know about BIOS/GPT incompatibilities. |
| 456 | |
| 457 | 0.6.7 (5/1/2010): |
| 458 | ----------------- |
| 459 | |
| 460 | - Undid earlier change, with version 0.6.4, that wiped the MBR boot loader |
| 461 | when doing MBR-to-GPT conversions. I've now become skeptical that MBR |
| 462 | boot loaders were causing any real problems on GPT disks, so I'm going |
| 463 | back to the philosophy of leaving as much alone as possible. |
| 464 | |
| 465 | - Fixed bug that caused incorrect reporting of free space on 0-size disks |
| 466 | (e.g., files of 0 length passed as disk images). |
| 467 | |
| 468 | - Fixed bug that caused segfault on some invalid disks |
| 469 | |
| 470 | - Fixed bug that caused incorrect partition numbers to be displayed for |
| 471 | some verify problems. |
| 472 | |
| 473 | |
| 474 | 0.6.6 (3/21/2010): |
| 475 | ----------------- |
| 476 | |
| 477 | - Added support for the "no block IO protocol" (referred to as "hide from |
| 478 | EFI" in GPT fdisk) and "legacy BIOS bootable" attribute bits. See Table |
| 479 | 19 of the UEFI 2.3 specification (p. 153) for details. |
| 480 | |
| 481 | - Changed the sequence in which GPT data structures are written to disk; |
| 482 | backups are now written first, followed by the main structures. This is |
| 483 | as recommended in the UEFI 2.3 specification, since it's safer in the |
| 484 | extremely unlikely event that a RAID array's size is increased and |
| 485 | there's a power outage mid-write. (If the main structures are written |
| 486 | first in this case, they'll point to data that's not yet been written; |
| 487 | but by writing the backups first, the old main structures will still |
| 488 | point to the valid old backup structures.) |
| 489 | |
| 490 | - Protective MBRs now have disk signatures of 0x00000000, to better |
| 491 | conform with GPT as described in the UEFI 2.3 specification. |
| 492 | |
| 493 | - Added alignment information to the summary data produced by the |
| 494 | 'p' main-menu option in gdisk or the -p option to sgdisk. |
| 495 | |
| 496 | - More alignment changes: GPT fdisk now attempts to determine the alignment |
| 497 | value based on alignment of current partitions, if any are defined. If no |
| 498 | partitions are defined, a default value of 2048 is set. If the computed |
| 499 | value is less than 8 on drives over about 596GiB, it's reset to 8, since |
| 500 | the drive might be a WD Advanced Format unit that requires an 8-sector |
| 501 | (or larger power-of-2) alignment value for best performance. The |
| 502 | 2048-sector default provides better alignment in some RAID |
| 503 | configurations. |
| 504 | |
| 505 | - Changed behavior when a backup restore fails. Previously, GPT fdisk |
| 506 | would create a fresh blank set of partitions. Now it does so only |
| 507 | if the failure occurs when interpreting the backup's contents; if the |
| 508 | user typed the wrong filename, the in-memory data structures aren't |
| 509 | touched. |
| 510 | |
| 511 | |
| 512 | 0.6.5 (3/7/2010): |
| 513 | ----------------- |
| 514 | |
| 515 | - Added tests to verify ('v') function and to pre-save checks to look for |
| 516 | partitions that end before they begin or that are too big for their |
| 517 | disks. |
| 518 | |
| 519 | - Fixed a bug that could cause spurious data to appear in a grown partition |
| 520 | table. |
| 521 | |
| 522 | - Added ability to convert some or all partitions to logical partitions in |
| 523 | GPT-to-MBR conversion. This feature is limited by the fact that at least |
| 524 | one free sector must exist immediately prior to each logical partition, |
| 525 | so it won't do much good if partitions are crammed together. It should be |
| 526 | possible to convert back to MBR any disk that started that way, provided |
| 527 | no partitions were added or resized when the disk was in GPT form; and |
| 528 | disks that were partitioned with Apple's Disk Utility or other tools that |
| 529 | insert unpartitioned space should also be convertible. CAUTION: THE |
| 530 | LOGICAL PARTITION CREATION FEATURE DOESN'T TRY TO ALIGN PARTITIONS OR |
| 531 | PARTITION HEADER DATA TO CYLINDER BOUNDARIES! It's conceivable that some |
| 532 | older OSes or utilities will object to these disks, although Linux, OS X, |
| 533 | Windows Vista, and Windows 7 all seem happy with them. |
| 534 | |
| 535 | - Fixed bug that caused creation of 0-length file if an incorrect device |
| 536 | filename was typed. |
| 537 | |
| 538 | - The gdisk program now prompts for a device filename if it's called with |
| 539 | no options. This enables gdisk to do something useful if it's launched by |
| 540 | double-clicking its icon in a GUI environment. |
| 541 | |
| 542 | - Added workaround for bug in some versions of MinGW that caused the |
| 543 | program to garble input sector numbers. |
| 544 | |
| 545 | - The Windows version now works on disks with over-512-byte sectors. |
| 546 | Tested on a magneto-optical (MO) drive with 2048-byte sectors. |
| 547 | |
| 548 | - Added -D (--display-alignment) option to sgdisk, to display sector |
| 549 | alignment value (by default, 1 for sub-800GiB disks and 8 for disks |
| 550 | over that size). |
| 551 | |
| 552 | - Fixed bug in computation of CHS geometries for protective MBR. This is |
| 553 | non-critical, since most modern utilities ignore the CHS geometries. |
| 554 | Concerned users can use the 'n' option on the experts' menu to build new |
| 555 | protective MBRs with the new algorithm, if desired. (Note that GNU |
| 556 | Parted, at least, gets this wrong, too.) |
| 557 | |
| 558 | - Fixed memory-allocation bug when reading GPT disks with partition tables |
| 559 | with over 128 entries; could cause program to crash on startup. |
| 560 | |
| 561 | 0.6.4-2 (2/20/2010): |
| 562 | -------------------- |
| 563 | |
| 564 | Note: Neither of the following changes affects actual program code, so I've |
| 565 | left the version number in the program at 0.6.4. |
| 566 | |
| 567 | - Altered Makefile to pass user's compiler and linker environment |
| 568 | variables through. |
| 569 | |
| 570 | - Added #include to gpttext.cc to enable it to compile on the latest |
| 571 | GCC versions (it was failing on at least some 4.4.x compilers). |
| 572 | |
| 573 | 0.6.4 (2/19/2010): |
| 574 | ------------------- |
| 575 | |
| 576 | - Added -m (--gpttombr) option to sgdisk, enabling conversion of GPT |
| 577 | disks to MBR format, with a limit of four partitions total, and of course |
| 578 | without overcoming the 2TiB limit. |
| 579 | |
| 580 | - Added -h (--hybrid) option to sgdisk, enabling creation of hybrid |
| 581 | MBRs. Fewer options are available in sgdisk than in gdisk, though, |
| 582 | in order to keep the user interface manageable. |
| 583 | |
| 584 | - Fixed off-by-one bug in specification of partition when using the |
| 585 | -T (--transform-bsd) option in sgdisk. |
| 586 | |
| 587 | - Changed the code to create a new MBR unique disk signature whenever a new |
| 588 | protective MBR is generated (when doing an MBR-to-GPT conversion, when |
| 589 | using the 'n' option on the experts' menu, or when using the 'o' option |
| 590 | on the main menu, for example). Previous versions attempted to preserve |
| 591 | the existing MBR disk signature in most cases, but this resulted in |
| 592 | values of 0x00000000 whenever an empty disk was partitioned, and often in |
| 593 | other cases, too. Better to risk changing this value too often than to |
| 594 | leave multiple disks with 0x00000000 values, I think. |
| 595 | |
| 596 | - Added transpose ('t' on experts' menu in gdisk; or -r or --transpose in |
| 597 | sgdisk) command to enable fine-tuning partition order without doing a |
| 598 | full sort. |
| 599 | |
| 600 | - Added code to clear the MBR boot loader when doing an MBR-to-GPT |
| 601 | conversion. (This was already done in full-disk BSD-to-GPT conversions.) |
| 602 | This is done because I've seen a few problem reports that make me think |
| 603 | some MBR boot loaders freak out and hang the system when they encounter |
| 604 | GPT disks, and/or they attempt to load a second-stage boot loader stored |
| 605 | in what is now GPT territory, causing a system hang. Since MBR boot |
| 606 | loaders don't work on GPT disks anyhow (even GRUB needs to be |
| 607 | reinstalled), this new wiping behavior shouldn't cause any problems, and |
| 608 | may prevent a few. |
| 609 | |
| 610 | - Fixed bug in Windows version that prevented saving backup files. |
| 611 | |
| 612 | - Fixed bug that caused second and subsequent partition numbers in |
| 613 | prompts in hybrid MBR conversion procedure to be displayed in |
| 614 | hexadecimal. |
| 615 | |
| 616 | - Fixed very obscure potential bug in hybrid MBR/GPT synchronization when |
| 617 | deleting partitions; code wasn't matching partition lengths correctly, |
| 618 | which would only affect partitions that start at the same point but have |
| 619 | different lengths in MBR vs. GPT. |
| 620 | |
| 621 | - Fixed bug in the -E option to sgdisk; it was actually returning the |
| 622 | last free sector, not the last free sector in the largest free block. |
| 623 | |
| 624 | - Fixed bug in -t option to sgdisk; it was corrupting partition type |
| 625 | codes. |
| 626 | |
| 627 | - Fixed minor alignment bug in partition summary list ('p' from any menu) |
| 628 | when partition sizes are between 1000 and 1024 units. |
| 629 | |
| 630 | - Backup restore function ('l' on recovery & transformation menu) now |
| 631 | accepts both backups generated by GPT fdisk and backups created by a |
| 632 | direct copy (via dd, etc.) of the MBR, main GPT header, and main GPT |
| 633 | partition table, in that order. ("dd if=/dev/sda of=backup.gpt bs=512 |
| 634 | count=34" will do this on Linux for a disk with a typical-sized GPT table |
| 635 | of 128 entries.) |
| 636 | |
| 637 | 0.6.3 (2/3/2010): |
| 638 | ------------------ |
| 639 | |
| 640 | - Fixed serious data corruption bug on big-endian (PowerPC and similar) |
| 641 | systems. |
| 642 | |
| 643 | - Changed several GPT fdisk Solaris type codes to correct a duplicate |
| 644 | |
| 645 | - Corrected error in GPT fdisk type codes for NetBSD LFS and NetBSD RAID; |
| 646 | they were identical, but I've now changed NetBSD RAID to A906, which |
| 647 | is unique. |
| 648 | |
| 649 | - Added GUID for IBM General Parallel File System (GPFS) partition type |
| 650 | code. Somewhat arbitrarily set it to use the 7501 number (MBR code 0x75 |
| 651 | is used by IBM PC/IX, so it's at least the right company, by my loose |
| 652 | numbering rules....). |
| 653 | |
| 654 | - Improved GUID generation. Prior versions generated completely random |
| 655 | numbers for GUIDs. This works, but is technically a violation of the |
| 656 | spec. Unix versions now employ libuuid to generate GUIDs in a more |
| 657 | correct way. The Windows version still generates random numbers, though. |
| 658 | |
| 659 | - Turned PartTypes class into a derived class of GUIDData, and renamed |
| 660 | it to PartType. |
| 661 | |
| 662 | - Created new GUIDData class, to replace the original GUIDData struct. |
| 663 | |
| 664 | 0.6.2 (1/29/2010): |
| 665 | ------------------ |
| 666 | |
| 667 | - The change-type ('t' on main menu) option now changes the partition's |
| 668 | name *IF* the current name is the generic one for the partition type. |
| 669 | If the current name is not the generic name, it is NOT changed. |
| 670 | |
| 671 | - Fixed bug that caused new protective MBR to not be created when the |
| 672 | MBR was invalid and the GPT was damaged and the user opts to try to |
| 673 | use the GPT data. |
| 674 | |
| 675 | - Enabled default partition type code of 0700 when creating partitions |
| 676 | or changing their type codes. (Type 0700, Linux/Windows data, is set if |
| 677 | the user hits the Enter key alone.) |
| 678 | |
| 679 | - Fixed bug in sort ('s' on main menu) option that caused partition |
| 680 | numbers to begin at more than 1 if the original partition list had |
| 681 | too many empty partitions before the last one defined. |
| 682 | |
| 683 | - Improved code to determine which partition table to load in case of |
| 684 | CRC mismatches between the partition tables and the stored CRC values |
| 685 | in the headers. |
| 686 | |
| 687 | - Compiles using MinGW (http://www.mingw.org) to create a Windows binary. |
| 688 | |
| 689 | - Moved all disk I/O functions to the new DiskIO class. This helps with the |
| 690 | Windows port; it uses diskio-windows.cc for Windows-specific code, |
| 691 | diskio-unix.cc for the Linux, FreeBSD, and OS X code, and diskio.cc for |
| 692 | cross-platform disk I/O code. |
| 693 | |
| 694 | - Changed BSD disklabel detection code to be more correct (I think). |
| 695 | This change has no effect on my test disks, but I hope it'll work |
| 696 | better on disks with sector sizes other than 512 or 2048. |
| 697 | |
| 698 | 0.6.1 (1/20/2010): |
| 699 | ------------------ |
| 700 | |
| 701 | - Fixed bug that returned incorrect disk size on 32-bit versions of |
| 702 | FreeBSD. |
| 703 | |
| 704 | - Fixed bug that prevented FreeBSD version from working on disk image |
| 705 | files. |
| 706 | |
| 707 | - Fixed bug that caused BSD disklabel conversion to fail. |
| 708 | |
| 709 | 0.6.0 (1/15/2010): |
| 710 | ------------------ |
| 711 | |
| 712 | - Fixed bug that caused the convert to MBR function to fail. |
| 713 | |
| 714 | - Added support for disks with other than 512-byte sectors. |
| 715 | |
| 716 | - Created embryonic sgdisk program. |
| 717 | |
| 718 | - Fixed bug that caused relative sector numbers entered by users (e.g, |
| 719 | "+128M") to be misinterpreted as from the start of the range rather than |
| 720 | from the default value. |
| 721 | |
| 722 | 0.5.3 (1/4/2010): |
| 723 | ----------------- |
| 724 | |
| 725 | - Fixed bug in display of GUIDs when compiled with some versions of GCC. |
| 726 | |
| 727 | - Eliminated warnings caused by additional checks in latest versions of |
| 728 | GCC. These warnings were harmless, but to eliminate them I've added |
| 729 | more error checking on disk I/O. |
| 730 | |
| 731 | - Eliminated unnecessary warnings about potential data loss if the program |
| 732 | was launched with the -l option or if writes aren't possible. |
| 733 | |
| 734 | - Added code to set the partition boundary value based on the physical |
| 735 | sector size. (FindAlignment() function.) This function, however, works |
| 736 | only on Linux, and then only if the BLKPBSZGET ioctl is defined. This |
| 737 | ioctl is new in kernel 2.6.32 or thereabouts. |
| 738 | |
| 739 | 0.5.2 (12/31/2009): |
| 740 | ------------------- |
| 741 | |
| 742 | - Modified partition creation function to begin partitions on 8-sector |
| 743 | boundaries by default. This improves performance on the new Western |
| 744 | Digital Advanced Format drives. The new 'd' and 'l' options on the |
| 745 | experts' menu display and change, respectively, the boundary size. |
| 746 | |
| 747 | - Tweaked code to produce fewer warnings on the latest versions of |
| 748 | GCC. |
| 749 | |
| 750 | 0.5.1: |
| 751 | ------ |
| 752 | |
| 753 | - Made some minor edits to the man page. |
| 754 | |
| 755 | - Incorporated RPM .spec file changes contributed by Scott Collier |
| 756 | (boodle11@gmail.com). |
| 757 | |
| 758 | - Changed method of locating and loading backup GPT data, to use the |
| 759 | main header's pointer, if it's valid, rather than seeking to the |
| 760 | end of the disk. |
| 761 | |
| 762 | - Added 'e' option (relocate backup GPT data structures) to the experts' |
| 763 | menu. |
| 764 | |
| 765 | - Fixed bug that prevented recovery of partitions in case of partially |
| 766 | damaged GPT data (bad main and good backup or bad backup and good |
| 767 | main header, for instance). |
| 768 | |
| 769 | 0.5.0: |
| 770 | ------ |
| 771 | |
| 772 | - Added GPT-to-MBR conversion function. It's very limited, but potentially |
| 773 | useful in some cases. |
| 774 | |
| 775 | - Fixed bug that caused incorrect file sizes to be reported on 32-bit |
| 776 | Linux, thus causing problems when editing partition tables in disk images |
| 777 | or when loading GPT backup files. |
| 778 | |
| 779 | - Fixed bug that caused bogus CRC error reports when loading backup GPT |
| 780 | data. |
| 781 | |
| 782 | - Reorganized menus. There are now three: the main menu, the experts' menu, |
| 783 | and the recovery & transformation menu. The last of these has most of the |
| 784 | items that had been on the earlier versions' experts' menu. |
| 785 | |
| 786 | - Added ability to re-load the MBR and generate a fresh GPT from it. This |
| 787 | is normally identical to quitting and re-running the program, but it |
| 788 | could be handy if, say, the GPT partitions on a hybrid configuration are |
| 789 | badly messed up; this will enable using the hybridized partitions as the |
| 790 | starting point for a new GPT setup. |
| 791 | |
| 792 | - The program now generates CHS values for hybrid and GPT-to-MBR conversion |
| 793 | MBRs. For the moment, the assumption is the maximum number of heads and |
| 794 | sectors per track (255 and 63, respectively), although the bulk of the |
| 795 | code supports other values -- it'd just be awkward to enter the data in |
| 796 | the user interface. |
| 797 | |
| 798 | - Fixed minor display bug that caused number of sectors on the disk to be |
| 799 | shown as 0 on large disks when running 32-bit binaries. |
| 800 | |
| 801 | - Reverted 0.4.2's zap (destroy GPT) changes, since I don't want to wipe |
| 802 | out a valid MBR if the user created that MBR over an older GPT without |
| 803 | first properly wiping out the GPT, and the user now wants to wipe out |
| 804 | the GPT. |
| 805 | |
| 806 | - Reformatted and edited the man page. Aside from edits related to the |
| 807 | preceding program changes, I've altered the markup slightly and trimmed |
| 808 | much of the more tutorial information from the man page to better |
| 809 | conform to typical terse man page style. |
| 810 | |
| 811 | 0.4.2: |
| 812 | ------ |
| 813 | |
| 814 | - Code cleanup. |
| 815 | |
| 816 | - Fixed very small formatting bug in display of hex code when a match isn't |
| 817 | found when converting from an MBR/gdisk hex code to a GUID type code. |
| 818 | |
| 819 | - Added the ability to work on disk image files (raw files for virtual |
| 820 | machines, backup images, etc.). The program assumes that all such disk |
| 821 | image files have 512-byte sectors. |
| 822 | |
| 823 | - Added verification prompt to 'o' main-menu option to avoid accidental |
| 824 | erasures of all partitions. |
| 825 | |
| 826 | - The "destroy GPT data structures" option ('z' on the experts' menu) now |
| 827 | also destroys all EFI GPT (0xEE) partitions in the MBR. |
| 828 | |
| 829 | - Added an extra warning to the "destroy GPT data structures" option if an APM |
| 830 | or BSD disklabel was detected on the disk. |
| 831 | |
| 832 | - Added a buffer flush after destroying GPT data structures, to get the OS |
| 833 | to read the new (empty or MBR-only) partition table. |
| 834 | |
| 835 | - Fixed bug that allowed entry of nonexistent partition numbers when creating |
| 836 | a hybrid MBR. |
| 837 | |
| 838 | 0.4.1: |
| 839 | ------ |
| 840 | |
| 841 | - Code cleanup/re-organization |
| 842 | |
| 843 | - Partition creation function ('n' on main menu) now uses the start of the |
| 844 | largest available chunk of free space rather than the first available |
| 845 | sector as the default starting sector number. This should enable easier |
| 846 | partition creation if there are small bits of free space on the disk. |
| 847 | |
| 848 | - You can now specify the end point of a partition by using a minus sign, |
| 849 | in which case the end point is the default value minus the specified |
| 850 | size. For instance, "-200M" creates a partition that ends 200MiB before |
| 851 | the default end point. |
| 852 | |
| 853 | - You can now specify the start point of a partition by using a plus or |
| 854 | minus sign, in which case the start point is the specified distance from |
| 855 | the start (+) or end (-) of free space. This is exactly the same as the |
| 856 | new rules for entry of the end point, except that the default value is |
| 857 | set differently. |
| 858 | |
| 859 | - Deleting a partition now checks for a matching hybrid MBR partition, and |
| 860 | if one is found, it's deleted. Any empty space that then surrounds the |
| 861 | 0xEE (EFI GPT) MBR partitions is then added to the nearby 0xEE partition. |
| 862 | If no non-0xEE partitions are left, a fresh protective MBR is generated. |
| 863 | |
| 864 | - Added hybrid MBR consistency check to the verify ('v') option and to |
| 865 | pre-write checks. If non-0xEE/non-0x00 MBR partitions without |
| 866 | corresponding GPT partitions are found, the user is warned. This finding |
| 867 | does NOT prevent writing the partition table, though. |
| 868 | |
| 869 | - Added non-destructive write test when opening the device file, in order |
| 870 | to detect the problem with FreeBSD being unable to write to disks with |
| 871 | mounted partitions (or other potential problems). |
| 872 | |
| 873 | 0.4.0: |
| 874 | ------ |
| 875 | |
| 876 | - Added support for BSD disklabels. The program can now convert disks that |
| 877 | use "raw" disklabels, with the caveat that the first partition will |
| 878 | almost certainly need to be deleted because it'll overlap the main GPT |
| 879 | header; and convert disklabels contained within a GPT (or a former MBR, |
| 880 | converted to GPT) partition. In the latter case, the 'b' main menu option |
| 881 | is used. |
| 882 | |
| 883 | - Added support for compiling on FreeBSD. |
| 884 | |
| 885 | - Fixed bug that could cause crashes or incomplete sorts when sorting |
| 886 | the partition table. |
| 887 | |
| 888 | - New partitions, including converted ones, now take on the name of the |
| 889 | partition type as a default name. |
| 890 | |
| 891 | - Reorganized some code; created a separate C++ class for GPT partitions |
| 892 | (GPTPart), which replaced a struct and enabled moving code from the |
| 893 | bloated GPTData class into GPTPart. |
| 894 | |
| 895 | - Fixed a bug that produced spurious warnings about unknown sector sizes |
| 896 | when loading a backup file. |
| 897 | |
| 898 | 0.3.5: |
| 899 | ------ |
| 900 | |
| 901 | Note: This version was not officially publicly released; I wanted to test |
| 902 | the big-endian support while developing 0.4.0. |
| 903 | |
| 904 | - Tweaked the disk type identification code to warn users to re-sync their |
| 905 | hybrid MBRs when one is detected. |
| 906 | |
| 907 | - Tweaked MBR-reading code to ignore 0xEE (EFI GPT) partitions. This will |
| 908 | only have an effect on a poorly partitioned MBR disk that contains an |
| 909 | inappropriate EFI GPT partition, or when attempting to recover a |
| 910 | corrupted disk by using the hybrid MBR for data recovery. |
| 911 | |
| 912 | - Added big-endian (PowerPC, etc.) support! |
| 913 | |
| 914 | - Added code to identify and warn of the presence of an Apple Partition |
| 915 | Map (APM) on the disk. |
| 916 | |
| 917 | - Enabled MBR conversion code to handle multiple logical partitions. |
| 918 | |
| 919 | 0.3.4: |
| 920 | ------ |
| 921 | |
| 922 | - Fixed bug that enabled (possibly accidental) entry of MBR type codes of |
| 923 | 0x00 in GPTData::MakeHybrid(). The fix also enables entry of default |
| 924 | type code by pressing the Enter key when prompted. Applied a similar |
| 925 | fix to the entry of the type code for the second protective partition, |
| 926 | if one is used. |
| 927 | |
| 928 | - Fixed a typo: "sectors" was spelled "sectprs" in one spot! |
| 929 | |
| 930 | - Fixed bug that caused default entry for end sector to be refused if an |
| 931 | initial value using a plus sign (e.g., "+20G") was also refused. |
| 932 | |
| 933 | 0.3.3: |
| 934 | ------ |
| 935 | |
| 936 | - Gave users control over the way MBR partitions are assigned to slots in a |
| 937 | hybrid MBR setup; the original method (putting the 0xEE partition after |
| 938 | the real partitions) works well for non-boot disks, but both GRUB and |
| 939 | GRUB2 become confused by this type of setup, so it needs changing. |
| 940 | |
| 941 | - Changed "blocks" to "sectors" in GPT and MBR table displays. |
| 942 | |
| 943 | - Added "Boot" column to MBR table display; shows an asterisk (*) when the |
| 944 | partition's status is bootable. |
| 945 | |
| 946 | 0.3.2: |
| 947 | ------ |
| 948 | |
| 949 | - Changed __DARWIN_UNIX03 to __APPLE__ as code to enable MacOS X support. |
| 950 | |
| 951 | - Added the ability to create a hybrid MBR ('h' on experts' menu). This was |
| 952 | motivated by my discovery that Windows 7 remains brain-dead when it comes |
| 953 | to the ability to boot from a GPT disk, at least on BIOS-based machines. |
| 954 | |
| 955 | - Added 'z' option to experts' menu, to destroy GPT data structures and |
| 956 | exit. The intent is to use this feature to enable subsequent partitioning |
| 957 | of the disk using fdisk or other GPT-unaware tools. (GNU Parted will wipe |
| 958 | the GPT data structures itself when you create a new MBR ["msdos |
| 959 | disklabel," in Parted parlance], so using Parted is another option.) |
| 960 | |
| 961 | - Slightly altered the effect of the 'o' command on the main menu. It now |
| 962 | blanks out the protective MBR, as well as the GPT data. |
| 963 | |
| 964 | 0.3.1: |
| 965 | ------ |
| 966 | |
| 967 | - Added Mac OS X support, provided as a patch by David Hubbard |
| 968 | (david.c.hubbard@gmail.com). |
| 969 | |
| 970 | - Fixed bug in disksize() function on Mac OS. (Possibly dependent on the |
| 971 | kernel and/or GCC version.) The disk size, of type uint64_t, was not |
| 972 | being passed correctly, so I reorganized the function to return it as |
| 973 | the function's return value rather than as a parameter. This seems to |
| 974 | work OK on my Mac OS test system and on both 32- and 64-bit Linux |
| 975 | systems. |
| 976 | |
| 977 | - Fixed off-by-one bug in GPTData::FindLastAvailable(). |
| 978 | |
| 979 | - Fixed bug that caused display of options after a disk-write error. |
| 980 | |
| 981 | - Fixed several incorrect MacOS X partition type GUIDs, thanks to Yves |
| 982 | Blusseau (1otnwmz02@sneakemail.com). |
| 983 | |
| 984 | 0.3.0: |
| 985 | ------ |
| 986 | |
| 987 | - Changed version number to 0.3.0, reflecting the fact that I've received |
| 988 | no significant bug reports and so am elevating the program to "beta" |
| 989 | status. This change also entailed altering the warning the program |
| 990 | displays when saving partition table changes. |
| 991 | |
| 992 | - Fixed minor bug in CHS geometry of the protective MBR's type EE partition |
| 993 | (was producing 0x000200 as the start value, but should be 0x000100). |
| 994 | Should be a non-critical bug since the protective MBR partition |
| 995 | definition is only there to keep MBR-only disk utilities from messing |
| 996 | with the disk. |
| 997 | |
| 998 | - Added ability to enter GUIDs as single massive strings rather than in |
| 999 | chunks. |
| 1000 | |
| 1001 | 0.2.2: |
| 1002 | ------ |
| 1003 | |
| 1004 | - Added #include directives required to compile the program using GCC |
| 1005 | 4.4.0. |
| 1006 | |
| 1007 | 0.2.1: |
| 1008 | ------ |
| 1009 | |
| 1010 | - Fixed partition numbering problem in reports of partition overlaps in |
| 1011 | verification function. |
| 1012 | |
| 1013 | - Fixed 1-sector partition size problem when creating new partitions |
| 1014 | (partitions were 1 sector too big when using the +size option). |
| 1015 | |
| 1016 | - Changed BytesToSI() to display values in bytes without decimal points |
| 1017 | (e.g., "512 bytes" rather than "512.0 bytes"). |
| 1018 | |
| 1019 | - Added GPTData class member functions to retrieve GPT data structure |
| 1020 | locations on disk; used in my internal-use-only GPT-wiping program. |
| 1021 | |
| 1022 | - Eliminated the "a reboot is recommended" notice after writing the |
| 1023 | partition table. |
| 1024 | |
| 1025 | - Added notice after sorting the partition table to the effect that |
| 1026 | editing /etc/fstab and/or the boot loader files may be required. |
| 1027 | |
| 1028 | - Fixed bug in MBR-reading function that caused 0x0f (Win95 LBA) and 0x85 |
| 1029 | (Linux extended) extended partitions to not be read. |
| 1030 | |
| 1031 | - Fixed bug in GetLastSector() (in support.cc) that would have prevented |
| 1032 | correct user entry of over-32-bit sector numbers on 32-bit systems. |
| 1033 | |
| 1034 | - Made some changes/corrections to the partition type list in |
| 1035 | parttypes.cc. Most of these were based on newly-discovered MBR type |
| 1036 | codes for Apple (Mac OS X) filesystems. |
| 1037 | |
| 1038 | - General code cleanup (setting explicit casts, etc.) |
| 1039 | |
| 1040 | 0.2.0: |
| 1041 | ------ |
| 1042 | |
| 1043 | - Initial semi-public release |
