Hotshot,
I used to do all my work on flash drives for 2 years then one day - blank - everything gone. I tried flash memeory recovery tools but nothing worked. In the end I downloaded a hex editor and began stepping through the drive in ascii mode, looking for blocks of text and slowly, slowly reconstructing all my source I had lost. It took me a whole weeknd of work to recover stuff.
If you have lost images or music or similar I think its easy to recover them using tools but if its data or text files, I can help you recover if the stuff is ciritcal but it takes a long, long time.
