Hi Bryan

I've had this problem recently and if you look at the recent thread 'powerbook kernel panic' or along those lines that is the same too.

I am very suspicious considering your incident makes three of this kind I have heard of this week.

I was unable to fix mine. You cannot use holding t at start-up to connect via firewire to another cmputer. It is very odd and I find it very dodgy that these occurances are so close together on similar computers.

As for stuck discs just hold down the click as you start-up.

Sorry I can't be more help but I hope more about it is uncovered soon
