Okay, I've searched the forums pretty thoroughly, but no one has listed these exact symptoms. I've got a PowerPC G5 running 10.4. After four years of dedicated service, my Superdrive gave out, so I bought a Sony drive (SONY DVD RW DRU-842A in profiler) to replace it. Here's the trouble: Any time the machine goes to sleep with a disc in the drive, it won't eject when I wake it up. I have to restart, then eject. Other than that, the drive works beautifully. If this question has been answered elsewhere, please redirect me there, sorry for the repost. Speaking of sleep, when I put the machine to sleep through the menu it goes fully to sleep (no fan/other noise). But when it goes to sleep on its own, I can still hear the machine churning away. Any ideas? My roomate has a newer mac pro that doesn't do this. Thanks, everyone.
