| 261 | data on your device (created by non-Linux tools such as M-Systems' |
| 262 | DOS drivers), your data might overlap the area Linux wants to use for |
| 263 | the BBT. If this is a concern for you, leave this option disabled and |
| 264 | Linux will not write BBT data into this area. |
| 265 | The downside of leaving this option disabled is that if bad blocks |
| 266 | are detected by Linux, they will not be recorded in the BBT, which |
| 267 | could cause future problems. |
| 268 | Once you enable this option, new filesystems (INFTL or others, created |
| 269 | in Linux or other operating systems) will not use the reserved area. |
| 270 | The only reason not to enable this option is to prevent damage to |
| 271 | preexisting filesystems. |
| 272 | Even if you leave this disabled, you can enable BBT writes at module |
| 273 | load time (assuming you build diskonchip as a module) with the module |
| 274 | parameter "inftl_bbt_write=1". |
