I've had my powerbook for about a month now and until recently i hadn't used the superdrive much. I just finished backing up some of my data onto a DVD+RW and couldn't help but notice the noise coming from the superdrive. The drive just whirls away for the majority of the time. Then occasionally you here the head (I suppose) zipping around together with what I can only describe as a grinding noise. Like the kind of sound you'd expect to hear when a little plastic wheel with teeth is slipping when it isn't supposed to. Anybody else experience these noises from the superdrive? Do you think its worth reporting to Apple. I'm afraid I might had a faulty superdrive! It seems to burn/ read everything fine by the way.
