A mate came across Anadisk and used it to copy a protected floppy for the owner. Scandisk reported bad sectors, but the actual protection was something like a sector size change.
Anyway, it apparantly read bit by bit and wrote bit by bit.
He posed a question, why cant someone make a program to read cds bit by bit so that we'll be able to copy any protection, even ones with dual sectors.
I had no idea what to say because I dont know enough on the subject, so I thought Id ask CDFreaks.
