![]() ![]() especially if two instances of MTR are running, with different user privileges - as the wonderful sudo tool Pseudo allows one to do. However, there is another related problem that effects both internal & external drives and does absolutely require a restart: sometimes the dvd drive stutters video playback is halting and jittery and data access is atrocious (a 45 _minute_ RIP can take 10-20 *HOURS*). but cant be accessed.įor external drives, re-connecting the usb cable will often force the usb system driver / disk arbitration mechanism to reinitialize itself. However, i can confirm that the 'disappearing' dvd problem occurs on ppc mini's as well - among other macs the problem can also be one of 'lock-out- where the device seems to be registered in disk util / sys profile / finder / etc. I havent tried the sleep option - because i am scared to death i will suffer a one of notorious hang-on-wake situations - so i will have to wait until i dont have anything important enqueued to test this hint. I would never have believed that putting the Mac to sleep could be the solution! I'd be interested in any rational explanation of this behavior. I thought this hint, albeit totally straightforward, would be useful because I was very close to running to the nearest Mac support store. When I woke it up, the drive woke up as well, the DVD appeared, and I was able to eject it. I just had to put the Mac to sleep by closing the lid of the laptop. It looked like it was the end of the DVD drive, right? I restarted several times with no more luck. More worrying: System Information wouldn't see the DVD drive at all. I restarted again and pressed Command-O-F followed by eject cd. I restarted the Mac while pressing the mouse button down (both the track pad and then a USB mouse). I had the very unpleasant experience of a DVD drive seemingly dead with a DVD inside: I inserted a DVD in the drive, but it didn't mount and I couldn't eject it. ![]()
