Using readcd I copied a game which had a copy protection under windows. If you sequentially read the whole disc (as cd copy programs do) you would notice that certain sectors had medium faults. Every windows program my friends had tried aborted with tons of error messages. Readcd on linux also aborted. However, telling readcd to ignore errors and only retry three times I ripped an iso off the disc. Burning that to cd was of course no problem and then I had an identical copy. Well, not completely identical, since I didn't have the medium errors. Basically, readcd rules! David -- Hi! I'm a .signature virus.
