Try PC File Recovery, it has helped me more than a few times with lost data. It's free just do a google search. I've even found files with it after a quick format. Hope that helps you out, also you could always try looking in DOS to see what it sees, if it's there in DOS you can create a new directory and copy the files into it. If you don't know how to do that I can help just email me
