Hi Mike - just saw this. Do you still have the drive? If it died because of a head crash, you can try putting it in the freezer for about 10-15 minutes, then throwing it back in your laptop and see if it'll boot. Then just grab what you can untill it gets hot again and crashes. Then repeat. You do have to be careful of condensation, though. Otherwise, there are data recovery specialists out there that will actually take the drive apart and rebuild it. This is spendy, though.
As far as wiping the drive, it's much easier to do via software if the drive spins up. If not, well... you could try a really really big magnet... but then you'll never really be sure if it erased it completely or not...
There are other things you can try to get the data back, but these involve a pci adapter, a desktop, and some forensic utilities (software). But again, this is only if the drive spins up. It all depends on how the drive died.
Sorry this isn't a definitive answer, but maybe it'll work for ya... good luck!
