Hi, Patrick: I tested my badblocks (from E2fsprogs 1.22) on a Slackware 8.0 distribution using kernel 2.4.19 and when I 'badblocks -v -n /dev/hdb1' the following three lines appear immediately: Initializing random test data Checking for bad blocks in non-destructive read-write mode >From block 0 to 8225248 A portion of 'man badblocks' returns: -n Use non-destructive read-write mode. By default only a non-destructive read-only test is done. This option must not be combined with the -w option, as they are mutually exclusive. -v Verbose mode. What EXACTLY happens when you do the same?
