Random thought of the day....
I've seen a few CDs around where the manufacturer has deliberately included
errors on the disc to make piracy more difficult - which is a noble enough
thing to do, but a bit of a pain in the butt when you want to make a
legitimate backup copy of a disc :-(
Has anyone come across tools (Linux preferred, but I could stomach Windows if
I had to!) which can duplicate such discs and produce errors in the output at
the same block as the input? (I assume any software on such
deliberately-crippled media would check for the presence of known errors at
install / run time)
Its all pretty flakey, depends ALOT on the burner, the types of errors,
and the phase of the moon. The utilities are also pretty much Windows
only.
If the errors are from a common commercial copy protection
(SecurRom/SafeDisc), you'll have better luck.
See http://www.cdmediaworld.com/hardware/cdrom/cd_protections.shtml for
more than you probably wanted to know.
Look into products like CloneCD, or Alcohol 120. (Bigger list of
utilities here:
