I have a CD stuck in my Superdrive and have tried everything to get it out, I think its a hardware failure. It tries to read the disk 4 or 5 times, then tries to eject but gets so far then sucks it back in. Until I have time to look at this properly, is there a way to disable the Superdrive so it doesn't keep trying to read the disk and eject it, its driving me insane!
