I'm currently in the process of sending back the Pioneer DVR-109AB to OtherWorldComputing to upgrade to the brand new DVR-112D. Has anyone tried this drive yet in a Mac Pro? I had a strange issue with the DVR-109AB and it would suck to find out if the 112D has the same problem. Here's the problem I've been having with the 109AB. If the drive went to sleep after disc inactivity, then ejecting the disc would be weird. Lemme explain. After the drive is asleep (or spun down) I would try to eject the disc and here's what would happen: The cursor would get very jumpy or sluggish feeling as it skips around the screen when I move the mouse for about 10 seconds, then I'd hear the drive spin back up and the disc icon would unmount from the desktop (as if it's ejecting) but, nothing happens. Then, the disc would remount on the desktop as if I just put the disc in. Then, once all of that is back to normal, I can go ahead and eject it. Basically, I can only eject normally if the disc is still spinning. So, I'm sending it back. Now, for the original topic. Has anyone used this drive yet? Any problems with it?
