I had a similar problem and  couldnt see the files using linux ubuntu. Finally I was able to recover the files using Active@ Partition Recovery. On http://www.partition-recovery.com/ they have a freeware version to check whether you can actually see your files. If you can, you can purchase the full software to recover them.

Good luck
