i encountered CRC Error witha game disk
i've tried "Ultra ISO" for doing this to recover my GTA San Andreas (original) files, but it took
9 HOURS
for completing the process, & when i used
Daemon Tools, Alcohol, Nero... to mount them, they gave same error, that its a corrupt image...
my method which worked Flawlessly

- what i used -> a Vaccum Cleaner, Cotton Ear Buds.
First cleaned the Lens with the ear buds, then used the Blower of Vaccum Cleaner to blow out the Dust (did this two times) & also washed the DVD with Shampoo

, guess what that DVD still work
