For S.M.A.R.T. Hard drives, there’s Smart support.

It’s probably not what you are looking for, but it does provide a lot of information.

Thanks, Swiftd. It looks like that package still lacks the crucial ‘-e’ flag to report disk errors. I posted this questing back in April and received similar results – I just don’t think Linux has a way to report disk errors. It seems filesystem errors are as far as we can go.

There’s a sysstat package that can be downloaded that contains iostat for Linux: http://perso.wanadoo.fr/sebastien.godard/

Outside of gathering this info from /proc/partitions and /proc/stat, it’s probably your best option.

I don’t think this is what the poster is asking for. Solaris iostat gives output similar to:
solaris9-test% iostat -E

which reports disk-level errors. fsck runs a filesystem level check, and does not report disk errors.

First mount your hd to read-only.
secondly, if you are use ext3/ext2, e2fsck /dev/hda, if you are using reiser, then use the reiserfsck command
