I am a student. I backed up all my files onto a cd rw. When I reformatted my hard drive and tried to re install my work my pc tells me I have 640mb free space on the cd, there are no files.... I did delete the disk first, and I believe I wrote the files back onto it, about 400mb. I was using Adaptec Easy CD Creator 4. Is there a 'cheap' way to recover the data, either 1) the latest burn or 2) if I somehow didn't do the latest back up and simply deleted the previous, at least most of that will do for now I have tried 'Badcopy 3' but this still tells me there are no files.
