Not so much just for verification, but I'd also check out ddrescue. If the |
23 |
tool dumps your media easily, it's probably good. If it struggles, you may |

IIRC, some game discs may also throw a curve-ball here: they had |
27 |
intentional errors introduced near the end of the disc to prevent image |
28 |
dumping for copy protection. I'm sure I ran across a ps2 game or two like this. |
