Digital Mayhem is right!! Use CloneCD and no problems.....BUT....make an image on your hard drive first,,,then copy.
Click on the first button that says 'read to image' and then the 'image' tab. Select everything EXCEPT 'Don't report read errors'.
After your image is made, click on the 2nd button to burn your copy.
When reading your source disk it would be better to use your writer as the reader. Most writers read more accurately than cd-roms.
I hope this helps..........Good Luck.
