I'm on a 2.4 GHz previous generation black Macbook. I just inserted a DVD, and after spinning for a few seconds the drive stopped dead. No disk icon appeared on the desktop. When I press eject, the eject splash screen flashes on like normal, but nothing happens. System Profiler says under Disk Burning: "No burning device was found. If you are using an external device please make sure that it is connected and powered properly." Disk Utility doesn't show it either, only my hard drive. I booted into Windows Vista using Boot Camp, and Windows can't see it either. This Macbook is only about six months old, never had any issues before. I updated to 10.5.6 last week without any problems. I burned a few DVDs over the weekend, and watched a movie just yesterday. In either case there were no signs of any problems. I did have a strange episode earlier tonight where my Macbook mysteriously went to sleep as if it had lost power, but it was plugged into the AC adapter at the time. I had to do a hard reboot in order to revive the machine. Anybody have any ideas as to what's going on? I guess I'm going to have to call Apple after the holidays.
