google "unerase" or "undelete" or "restore deleted files"
If the space on the drive wasn't overwritten it's very easy to restore. There is heaps of tools out there, even freeware.
And do yourself a favour and dump that crap right away before you'll even suffer more.
I dont have the drive. its gone and I cannt find it. I replaced it and probably put it in the recycle bin. Any other way of retrieving if you have email and password for the wallet??
