Program called badblocks come packaged with well I know redhat;s releases. As far as stress/performance test, there are a couple. E2fsck has some options to do it also for ext2 and ext3 partitions which essentially runs badblocks in the background. Below I listed a few stess tests I have ran across in my linux usage. Some are more geared toward filesystem stressing than hd but can give an indication of both.

Hi.

There's a program called 'badblocks' which tests a drive for, yes, bad blocks, and outputs a list of the blocks it finds (see man badblocks). The output from this program can be fed to mke2fs or whatever or can be output to a file.

I would personally avoid using a disk which reports bad blocks to the OS. These errors tend to get worse.
