I have a 867mhz G4 12 PB that won't eject my Ubuntu 6.06 disc. I installed Ubuntu, ran it some, and was going to try something else off the disc (I forget what now), so I put it back in, finished, and wanted to release the disc. It ejected it from the desktop, but never came out of the drive. I tried booting into OS X via firewire from my other mac, it booted fine, showed the disc, and I tried ejecting. No luck. It ejected it off the screen, waiting 2-3 seconds, then showed up again. I also tried ejecting by holding down the trackpad button upon startup, no beans. Anyone have an idea whats going on? Is my drive cooked?
