Today I put a CD-RW into my iMac G4 (SuperDrive), and nothing happened whatsoever; the drive didn't spin up, no error message, nothing. I opened Disk Utility and it didn't show the CD or the drive on there. I tried it with another disc (my SimCity 4 CD) and got the same results. I restarted (with the CD-RW in the drive) but it still has shown no sign of spinning up the CD drive to read the thing. It was working fine when I burned a CD-RW (a different one) a few days ago. Has anyone experienced this, or know of a fix? Luckily the computer is insured via AppleCare, in case there's a serious hardware problem. update: I called AppleCare, and after unplugging various things and resetting the firmware, it still isn't showing any signs of life, so I'll take it to the local Apple reseller whenever I get around to it.
