Drive analysis tools?

[Wombat]

I'm looking for some drive diagnostic tools for work. Failure analysis stuff too. It's for a product we're developing at work, so money can be spent on the right product. We're using mostly Hitachi drives, and the filesystem is ffs. File system analysis would be nice, but we're definitely looking for low-level, physical info.

Any suggestions? I already have the DFT tool from Hitachi.
