iBook G3 Dual-USB HD

#1 Rhapsody · #1 October 15th, 2009, 09:35 PM

I have an iBook G3 Dual-USB and was wondering why my replacement HD won't work. The HD is a 80GB Toshiba MK8025GAS. I've tried the HD in my iBook twice now but it isn't recognized by Disk Utility. Would the fact that it is formated to boot a Intel Mac (aka GUID partition table) have anything to do with it? I know it is a good HD, as I boot from it quite often over USB.

P.S. I stuck in the old HD and it works fine. :?

Thanks,

Did you actually install the drive internally into the ibook? It won't mount but you should be able to reformat it in disk utility. The first thing I'd check is the HD flex cables connection to the logic board because any sudden vibration will make it pop loose because it isn't the most secure connection. Tape it down real good with some kapton tape.

Yes, I put the HD in the iBook, but when I boot from the Tiger Install Disks, Disk Utility won't find the drive. Should I try formating the drive as the PPC format, then stick it in?

GUID is wrong for a non-Intel based Mac.
So go with the PPC format.

I formated the drive as the PPC format and the Disk Utility on the Tiger install disk won't see the drive. I know the drive is working because I can hear the drive spinning. What should I do???

It takes so long to open this iBook and it doesn't work!

Boot to the Tiger installer the go to disk utility. Go to the partition button then select 1 partition leaving the format as Mac OS extended (journaled), then (very important here) go to the options button on the bottom and make sure its set to Apple Partition Map as opposed to GUID, then apply.

That's what I would do IF Disk Utility could see the drive, but it doesn't. I tried booting from my internal CD drive but now it won't work either. Both the CD and HD drives spin up but I can't see either. For some reason the HD is causing the CD drive not to work either.

What happens when you boot holding the option key? What device(s) does boot picker make available?
