First off, I'm not 100% sure if this is the right sub-forum but it seemed to be the most approriate one to ask this question. Anyways, My girlfriend recently moved in with me and with her came a crap ton of music discs and dvd's and I was wondering if there is some kind of software for Windows or OS X that can scan a disc for any defects. That way I don't start ripping a DVD or CD just to have it fail halfway through or something. The CD one is optional but I'd really like one that scan's DVD's for any defects before ripping. Any help is appreciated.
