Ripping with CDex from CCCD CD's is working. And it's very easy. If you choose the drive where the CD is in, CDex should immediately display the tracks whether it is CCCD or not. Well I've tried it with my H single a few minutes ago and it did work.
And about tracing the rim with a black marker, I wouldn't do it even if there was no other way to rip the CD, the CD was just too expensive if I would make a mistake and the CD wouldn't work afterwards I would kill myself
