Running as user nobody and with all your filesystems
remounted to readonly may be wise..
+Disktest
+
+ Does repeated accesses to a filespec and optionally writes to, reads from,
+ and verifies the data. By default, disktest makes assumptions about the running
+ environment which allows for a quick start of IO generation. However, Disktest has
+ a large number of command line options which can be used to adapt the test for a
+ variety of uses including data integraty, medium integraty, perforamance, and sim-
+ ple application simulation.
