I have Toast 10 and always get an error trying to copy CD's. Right now it's an MP3 CD that I made a few years ago.
Here is the error:
Sense Key = ILLEGAL REQUEST
Sense Code = 0x21, 0x02
Now I just upgraded to the newest version thinking it might fix it but it did not. I don't have any problems writing CD's from iTunes and I finally made a disk image of this CD and burned them using the finder with no problems.
For some reason though I can never seem to burn a good CD from Toast.
I am using an iMac Intel 2.4 GHz with 4GB RAM and OS 10.6.4
