Specs- 2006 1.66 Intel Duo w/ 2gb Ram (OSX 10.6.7). It is a fairly old machine. I do have the current firmware ( SMC Version (system): 1.3f4) so I still cannot decide if there was something newer or any other options. Weird. I didn't burn dvds/cds very often for the drive to failure. It's just a bit strange. I first noticed that I couldn't burn dvds randomly so I needed to copy data to an external drive to my UMBP. Obviously it isn't too helpful doing that. I somehow could manage watching DVDs on the Mini. Recently I then realized that the drive can't even load a CD installation disc for anything, so I had to download the .dmg from the manufacturer site. Besides- I could have missed something that could be an error about permissions or anything running the drive unless it is actually just a defective hardware part? I haven't noticed any other superdrive failures in the mac mini, so.. Thanks in Advance if anyone has any info that could help me. I know its an old machine that given, since I use it as a media center attached to a TV for the last years and its pretty helpful.
