Dead HDs

[weird_dave]

I've got some failed HDs, windows can't read them anymore and neither can linux. They spin up and I can hear the head move. HD led stays on until the system gives up trying.
Has anyone successfully used any software tools that can tell what's happened or attempt data recovery?

R-Studio - I swear by it now.
