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 integrity, medium integraty, performance, and simple application simulation. stress_cd Creates multiple read threads on the cdrom device. stress_floppy Tests the reading/writing/formatting on a floppy drive.
