Cactus Data Shield Workaround

I have a cd that with Clony XXL Ive identified as being protected by the Cactus Data Shield protection, however ive had no problems at all in playing (and copying) the cd.

A friend of mine has the exact same cd’s, but cant copy them (the program we use to copy them simply tells him that the audio tracks are in fact data tracks)

What gives? is it the cd-drive firmware or summut stupid like that.

I have 2 cd drives, a HP and a LG, (both old - 8x record speed), but the cd works fine in both.
