It's not like the badblocks command is particularly speedy, either. I imagine
that *any* thorough drive test would take a long while given today's typical
drive size.

I've seen several mentions of "dd" in this thread, and I'll say that I've
seen several recommendations elsewhere to use a simple:
dd if=/dev/ of=/dev/
forgot bs=1m or at least 64kB, unless you like to wait days with default
bs=512
to "refresh" the drive. That is, dd will read the

okok, dd it is. I'll remove all data beforehand just in case. Thank
you all for your replies.

you may "cure" badblocks by
dd if=/dev/zero of=/dev/disk bs=1m
(but cleaning all data)
Disk will try to remap badblocks then.
But remember that it only make it's life a bit longer. this disk

Hello list,
Can anyone please recommend to me a program that will stress-test a

Generally these utilities can use proprietary commands to exercise
self-test functions that generally aren't accessible to non-proprietary
test code.

That will show me thruput. I need to see if bad blocks or similar are
happening. Something like scandisk for instance.

Hello list,
Can anyone please recommend to me a program that will stress-test a
disk? If it matters, two are connected by firewire, another via usb.
Filesystem is ufs. I think I have a disk that might be about to fail,
but it only sometimes errors when under stress. I need to see if it
was a fluke
