If you're talking audio, cdparanoia should do the trick. It certainly
has here and only failed on the the most recent Norah Jones album (the
final 2 tracks would not come off).

For data, it depends on the data protection. Quite a lot of software now
uses an burn angle test. Basically, all CD recorders burn at a slightly
different angle. At the mastering process, the burn angle is encrypted
onto the disc (IIRC, it's in the q block). The software runs, checks the
angle and runs. When you copy the disc, the original burn angle is
copied, but the disc laser won't burn at the same angle, so the software
doesn't run.

Of course, it could also use marks on the disc (found on games - they
look like blue stripes).

CloneCD may copy these. There should be no reason why a sector by sector
copy of the CD shouldn't work.

It goes without saying that such a practise is illegal and may get you
locked up with a very nice man called "Spike"...

TTFN
