I want to make an backup of my gta vice city, its only cd 2 which is the problem, it has the crack on it, i tryed copying on nero but no success, i have clone cd but not much experience on it, what settings do i put on the game cd mode to copy the second cd, i want to know the read and write speeds plus the audio extraction quality

If it has a crack on it then it is no longer protected, use whatever settings you want. Nero should copy it just fine, if it can't then perhaps your disc is faulty.. Does it install/play ok?

Also the disc in question has no audio tracks so the audio settings are irellivant.

If the disc is damaged, then I would suggest a low reading speed so as to hopefully get an error free image.
