Pretty close to completely fed up with this piece of crap combo-drive. It just doesn't read discs consistently. Its still under warranty but I'm in the UK at the moment and will have to wait till I'm back in the states to take care of this dumb drive. Will an Apple store simply replace the drive? I don't want a new machine necessarily (unless of course they switch the HD for me). If the drive didn't burn CD's correctly I would have had a fit a long time ago.
