dd_rescue

I can't help thinking that dd_rescue might have other uses (but I can't think of any right off).

dd was originally used for hard drive maintenance and also became a staple of many forensics people's toolkits. The trick was that you had to know what you're doing. Encase has since simplified the process and its output is challenged less and less.

For you more paranoid types, this means that you should destroy even the damaged hard drives.
