I have a USB external harddrive that I suspect is on its last leg. I
would like some definitive way to determine the number of bad blocks.
I've run "fsck /dev/sdb1 -c" several times, but the only output is:
/dev/sdd1: 11/30539776 files (9.1% non-contiguous), 1006495/61049000 blocks
where that first number (1006495) goes up with every run of fsck -c. Is
that number the number of bad blocks? And if not, then how can I find out?
Hello Jeremy.
You could use "badblocks" perhaps. I have used it successfully on "real"
disks - I am not sure if it works on USB drives because I have not tried it.
badblocks <device path> does a read-only test or badblocks -n <device
path> does a "non destructive" read-write test
man badblocks will help I'm sure.

Denis
