22 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
24 at least still have a workable image by the time it is done.
26 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.
