Well my macbook has taken a bullet and gone to the great MacHeaven. The Superdrive failed to read Anything I put inside it, even failed to read the install disc. It would spin and then spit the disc out a few seconds later... I've seen a number of people have experienced similar things with the macbook superdrives. Looks like another REV A problem that needs to be sorted ASAP. My replacement is on order, two weeks till expected arrival and TNT will collect my faulty machine tommorow.
