I'm at a loss.
I have a 2 GHz PPC iMac G5 with 1GB of RAM and the Apple shipped SuperDrive (Matshita UJ-845; firmware revision DBN9). I'm running OS X 10.4.7 (8J135).
I just burned a PPC Ubuntu ISO using Disk Utility to a CD-R and got a successful burn message. However, even though the After Burning "Eject Disk" option was selected, Disk Utility did not eject the CD when it was finished.
Now, my iMac doesn't recognize a CD is loaded. Not with Finder, Disk Utility, nor command-line diskutil. The normal keyboard eject button won't eject the CD, nor will rebooting with mouse button depressed. Since Disk Utility doesn't recognize a disk is loaded, so it has no eject option available. There is no hardware eject button I can find (other than the one on the keyboard).
I've looked at both http://docs.info.apple.com/article.html?artnum=58566 and http://docs.info.apple.com/article.html?artnum=58465 and don't see a relevant solution.
I've booted to Open Freeware and tried the "eject cd" multiple times. I also reset NVRAM. I only got "ok" response to both of these.
When I reboot, there is a noise from the drive as if it's trying to recalibrate, so it at least appears to sense there's a disk inserted. When booted to OF, the drive spins continuously until I reboot to Mac OS.
I've seen lots of similar threads, but not one quite like this. Any suggestions?
Thanks in advance...
