I have a LG GCE-8320B (32/10/40) burner, I use CloneCD version 4.0.0.1, I think (well first 4.0 version, anyhow) I have been able to copy everything I though at it. I have not even had to use the clony settings at all. I use clony to check to see what it has on it and then go to clonecd and then use the default settings on the game profile. Use a slow read and slow write, with RAW DAO enable. And presto... good copies come out.
CloneCD is the program that sets the standards for all others to follow.
Good copying... Russ
