Hello. Wondered if anyone else is experiencing / has experienced the same problem as me. The superdrive in my 12" powerbook (1.33 GHz OS X 10.3.8) has taken to making the same noise it makes when ejecting a cd when there is nothing in it and I haven't pressed eject. Sometimes it does this out of the blue 3 or 4 times in succession. I have recently run the latest software update and can't remember experiencing this before (although I can't guarantee that) Any ideas anyone?
