You should see if you can find a copy of Easy Recovery Pro, it will allow you to recover files after a format (as long as the area of the HD that the files were stored on haven't been overwritten by new data).
My source code has been found on my flash stick under a directory I named "EvilDragon Software".
Well damn, i made it obvious, i DID back it up, and stupid me, forgot to check my software company name! (i was looking for "Source backup"), which is a folder I did create, but it was empty.
