Hi folks: I'm trying to remove a couple of hard drives in my brother's Power PC Mac but it's proved to be a real headache! The ultimate goal is to format the hard drives before discarding this dinosaur. Can anyone give me a hint on how to successfully remove the hard drives. I've gotten as far as to unplug the power cables, the data cables and several screws to remove the heat sink. But now I'm stuck! Help, please! Thanks!
