G4 PowerBook won't boot
I'm posting this question because I have some specific symptoms that aren't mentioned in any other post I've looked at.
I suspect the hard drive has gone bad. There is a repetitive clicking sound, and the PB will not boot past the gray screen. Don't even get the Apple logo in the middle. I have tried booting from a USB external drive that has my superdooper back up, but I only get the curly and straight arrow in the display. Nothing else ever appears. I don't know if it's necessary to have a firewire drive for booting purposes, and that may be why it won't boot off the USB drive.
It will not boot off an authentic Leopard install disc. In fact, it took me a couple hours to get the thing to eject. The PB has always been a little finicky with recognizing discs. It sometimes would take a few tries to get it to read DVD's, etc.
I would proceed directly to getting a replacement hard drive, but I'm not entirely sure that will solve the problem.
I've tried it in Target mode, but the attached Mac sees nothing. I suspect it's looking for the PB's HD and it's toast.
It may be that I need a new optical drive and hard drive. Appreciate any help sorting this out.
Is this a good question?
