CDRWIN won't read any of the ring sectors for me.
Don't know if I have a drive that I could use the swap trick on either... although I have a really crazy idea, so bear with me!
I have this really old 2x CD drive which interfaces through some old soundcard on ISA motherboards. Is there any chance that I'd be able to hack this beast to read the ring area as audio and get a raw dump of it, via rigging up an old PC with DOS or an early version of Windows?
My guess is that the drive can't read subchannels - or do much else, for that matter.
Slap me if that was the stupidest idea ever!
