Reinstalling Windows does not lead to permanent data loss. Data can still be recovered using Data Recovery Software. If you would like to recover the lost data then stop using the drive and make sure you do not save any data to the disk, as this would cause overwriting and permanent data loss.

Yes it really did work! My drive was "unreadable" by windows or anything else I threw at it. The drive was good, but no data. This software brought back about 95% of a 500GB drive!
