|Data recovery is likely where you'll end up. Along with Recuva, Pc Files Inspector is another one, but you really don't want to be installing anymore on that hard drive (that's the problem, installing to that hd may in fact be writing over more data), so optimally, you would hook it up to another system and run the recovery from the working system.|
I formatted (quick) a friends XP computer and reinstalled XP, then he says "all my wifes baby photos and stuff, I forgot to tell you to save them!" argh. But I was able to get it all back. The software used was not free and to it required a certain level of understanding, but it worked. Depends how important this data , you may wish to try a techie if you have no success.
To err is human but to really screw things up, you need a computer!
