Does anybody know of any good software to retrieve data off a hard disk after it's been wiped a couple of times? I'm wishing to run some experiments to see exactly how much you would need to wipe.

Recuva from Piriform. Free and effective.
Technically it can't be done if you've actually wiped the harddrive. If you on the other hand have simply told the harddrive "you may overwrite all these sectors", there are a lot of tools out there that can help you. But if you've told your harddrive, just once, to "overwrite all sectors with 0s right now", then it is impossible to recover even a fragment of data.
It's impossible with software. It might be possible to recover some sectors and fragments with specialized equipment.Quote:

It would still require extremely advanced tools to do, as in, actually analysing individual sectors with electron microscopes. You can't actually recover data from a completely wiped harddrive with just regular software.Quote:

File Shredder has a Gutmann algorithm that's specifically designed to annihilate any data beyond recovery, even by the most sophisticated methods. Really, though...this is excessive. If Recuva doesn't pick it up, nothing will within the next 20 years.
Personally I just use the Wipe Free Space feature of CCleaner every once in a while to make sure my deleted data is gone. It's simple to use and more than enough for most people.Quote:

I don't know about Mario, but I'm just paranoid.Quote:

All riiiight.
