Hello,
I have a 1.33ghz iBook G4, 14" LCD, with 512mb of RAM. I received it to fix from my roommate, because it kept freezing up on him. After using disk warrior to rebuild the then Tiger 10.4 disk a few times, i assumed it was the Harddrive going out, and replaced the HD with a new 120gb disk and installed 10.5 Leopard with HFS Journaling filesystem. It ran fine yesterday, and I installed iLife 09, and late last night it slowed down severely. The spinning wheel was barely turning so after 20 minutes I killed the power by holding down the power button. When i rebooted it would not boot. Booting in verbose mode shows that it hangs on the filesystem claiming that the journal magic is bad. This was the same problem he was having with the old HD, because I had to keep using diskwarrior to repair the disk, but the same issue comes up again either a few hours later or in a few days. I am lost as to what the problem is? Is the PATA hardware going out on the logic board? Could I just have been using two faulty disks, (the old and the new?). I guess the question is, has anyone seen this problem before with a constantly corrupting filesystem on an iBook? I have hit a dead end and am beginning to just assume the PATA interface on the logicboard is bad, but then again it works, most of the time. Any thoughts?
