Anyone know why nothing burns on my imac? Os 10.2, btw.

a couple of questions..

which iMac have you got and does it have a burner?

are you trying to use Disk Copy or Toast?

After over 1300 posts here you should know you have to give more information than that. Has it burnt in the past and stopped burning? Are you using Toast?

Yeah, I was thinking the same thing.
Just a suggestion, one thing you can do is to check the Apple System Profiler to check if your imac even has a cd-burner or the box of the iMac. (no offense)
Maybe try resetting the PRAM or the Power Manager?
Just some guesses because we don't know the specs of your imac....
