read about this a long time ago, tried it, and it works for me.
If you look at the bottom of your CD, you can see that about half a centimeter from the CD's outside edge, there is what appears to be "session seperation line." Everything after that line is your normal audio CD, everything before that, up to the edge of the CD, is the "copy protection."
Solution? Take a bit of scotch tape, colour it black, and stick it so it reaches from the outside edge of the CD, right up to where the copy protection ends and the 'normal' part of the CD begins. It can and should only be a tiny piece - don't need to tape the *whole* copy protection area away ;p
Now, when you put your CD into your drive, it will automically skip the copy porotection, and mount properly.
