I have a 1 year old MacBook Pro with a Dvd Superdrive (MAT****ADVD-R UJ-867).(No AppleCare) I did some very minor and minimal DVD/ CD burns during the year. And when I needed it most, it does not work. It gets the CD/DVD and has an odd beeping low tone sound, then ejects it a few seconds later. It does not read anything. I have tried resetting the NVRAM and some other methods here: http://db.tidbits.com/article/10562?print_version=1 but to no avail Please Help, or should i buy an external DVD drive already. Thanks in advance.
