At work I regularly need to test hard drives recovered from old machines to make sure they're in working order for use as spares.
I currently use badblocks to test these, along with a grep through dmesg to make sure no errors show up there.
Anyone know of a more extensive hard drive scanning/benchmarking utility? I've had a few drives that passed badblocks turn up with other issues.
fsck is not really helpful here, just to preempt anyone suggesting it; these drives are usually wiped clean.
