Hey all, My step-daughter just got a hand-me-down Powerbook G4 that I swear looks brand new. It's obviously been used, but not much at all. Anyway, I'm stumped with a problem. I'm used to working on PCs, and the only macs I've worked with so far are Intel-based, so I'm totally flying blind here. Started having random issues. Programs closing themselves, running slow, Disk Utility would run endlessly with no progress, etc. After a few hours of running Disk Warrior and Drive Genius 2, I THOUGHT I had it fixed. I was able to repair the disk, and repair permissions, and after testing and retesting and retesting I got to the point where I was getting ZERO errors on anything. I put the 2nd RAM chip back in, ran some more tests and thought we were good to go. Then we got a kernel panic while she was using it today. OK, here we go again. Tried Drive Genius. Kicked back an error and said to restart. Tried Disk Warrior. Kicked back an error and said it couldn't be rebuilt. Umm ok. Now what? When you try to boot from the HD it just sits at the Apple logo with the spinning graphic below it. Finally after a while (5 minutes?) it just shuts down. It will do this every time. We don't have the original OS X install disk. I only have a 10.4 install disk from an intel iMac and I can't boot to that. I'm assuming the HD is dying --- OR that some of the RAM really is bad and it somehow jacked up something on the HD when she started using it. I wanted to run memtest86 from a linux USB stick but couldn't get it to work, then burned a CD of a PowerPC build of Ubuntu 10.04 and it just booted right in and didn't give me the option to run memtest...argh... If I go out and grab a Firewire cable and boot into Target Disk Mode from my intel iMac, will I be able to run Disk Utility to do verify/repair and maybe even repair permissions at the same time? I'm struggling here, and my step-daughter is really bummed that she can't use her "new" laptop..... I'd be bummed to... she was going from an Asus eeePC to a shiny aluminum Mac...even if it is a few years old. ANY help is greatly appreciated!
