Hi.
My Mac is an iBook G4 1.33 Ghz running Tiger, 60 GB HD (no partitions), 726 MB of RAM. It's about 2 years old.
I was updating software (JAVA, I believe) and left the computer on overnight. In the morning, it was frozen - black screen, but still on. I restarted it and it went through the startup phase, but became stuck on a blue screen. I restarted several times, and that's all it did.
I used the Disk Tools from the AppleCare CD to check the computer. Everything was OK until it found a problem in the volume structure of my HD (This took about 8 hours). It repaired it.
However, when I restarted, I was shown the kernel panic screen (where it tells you in four languages to restart the computer.)
I tried to boot off the OS X CD to reinstall, but when it got to the "Select Destination" screen, there is no destination volume to choose from. There is nothing there.
I opened Disk Utility to try and see what the problem was with the drive. I tried to Verify the Disk, and the following error message came up:
Verifying Volume "***"
Invalid Volume Header
Checking HFS Plus volume.
Invalid B-tree node size.
The volume "***" needs to be repaired.
Error: The underlying task reported failure on exit.
1 HFS volume checked.
Volume needs repair.
So I tried to repair the disk, with the following message:
Verify and Repair disk "***".
Invalid Volume Header
Checking HFS Plus volume.
Invalid B-tree node size.
Volume check failed.
Error: The underlying task reported failure on exit.
1 HFS volume checked.
1 volume could not be repaired because of an error.
After checking online, I found several issues with B-tree node. Disk Warrior seemed to be the best chance for repairing the hard drive. I am in Brazil and need to get this fixed ASAP, and am unsure of the availability of DW here.
Given the age of the computer and HD, is this an HD failure? Will I need to replace the disk? Or is it possible it is simply a software problem?
Any ideas and advice would be great.
Thanks,
Ben
Hi Ben
DiskWarrior is the only Utility that may be able to repair this problem.
It could also be that the drive is bad, but if you can get DiskWarrior, give that a try.
If you've backed up your files, you could reformat the drive. If it reformats ok, run Disk Utility on it again and see if it comes up clean. If it still gives those errors, then the drive needs to be replaced.
