I've got a new Nehalem 3.2ghz quad-core Mac Pro to replace my old PC that failed. I've fortunately moved everything I needed from the PC - and I'm now ripping it apart for usable parts - and one of those parts is the DVD-RW drive, a Pioneer DVR-213LS - which worked perfectly in the PC it was previously in. I'd like to add it as a second optical drive in the Mac Pro. It seems that the small face-plate on the disc-tray needs to be removed from the tray in order for it to fit the moving door on the front of the computer. It works, sometimes - but other times it is slow to eject, won't eject at all, or if it does, it will eject violently fast under Mac OS X 10.5.6 - and then won't close. Has anyone else had similar problems? I know it is recommended to set them to CSEL mode - but this one has nothing like that on it. It's just the drive with the SATA/power connectors at the back.
