Hey folks, was wondering if anyone can help me out - I have a Powerbook G4 running OS/X 10.4.11 that's never given me any problems. Firefox was acting a little weird, so I restarted. Upon restart, I couldn't get past the grey boot screen with the Apple logo and spinning gear. I booted from the OS/X DVD, and tried running the Disk Utility. It said the volume had an invalid node structure and "The underlying task reported failure on exit." I bought and downloaded Disk Warrior 4 on a friend's MacBook Pro, and tried to connect to the Powerbook via Target Disk Mode. Unfortunately, when I attempt to do this, here's what happens: 1. I start the Powerbook while holding down "T". I then see the bouncing Firewire symbol. 2. Upon attempting to connect the Firewire cord, the Firewire symbol stops moving, and the Powerbook never shows up on the MBP. 3. The Powerbook won't show up in the MBP Disk Utility. It just says "Gathering Disk Information", and never stops. HOWEVER, if I unplug the Firewire cord, THEN Disk Utility finishing "gathering info" and the Powerbook's drive appears in Disk Utility, but I can't do anything with it because it's no longer connect physically. (Same goes for the System Profiler - it just loads and loads without end, until I physically unplug the FW cord, and then the PB shows under Firewire as Target Disk.) 4. I know the Firewire cords I've tried using work (they work with my external DVD burner). And I have no reason to suspect the Firewire port on the PB is bad. Anyone have any ideas? I have physical copies of Tech Tool Pro and Disk Warrior on the way in the mail, and I'm praying that I'll be able to boot from either and salvage something.
