I got Knoppix 5.0.1
If the partition itself is corrupted, I know of no Linux tool that will help you. The best tool that I have found for trying to recover files from a corrupted Windows partition is
Recuva, a free program that runs under Windows. To try to recover files this way you would need to install the corrupted disk into another Windows computer as a second (or third or fourth) drive. And, of course, there is a chance that the data is so badly damaged that you will not be able to get it back.
