Dear Joe,
Thanks for your answer! I've downloaded PhotoRec - CGSecurity, but I can't see how it could help me. In another forum they recommended Seagate File Recovery Software, but these softwares are intended to recover lost and deleted files. In my case, I have all the files in my hard drive, the problem is that they are corrupted, I can't read them. Do you know any software to fix corrupted files?
Dear MikeHawthorne, thanks for your tip, too!
