Question

What does this error code mean?

I just bought a used PowerBook (TiBook) Ethernet edition with upgraded processor from 667 to 800 mHz. It has OS 10.4.11 installed.

I decided to run TechTool Pro (4.0.3) to do some maintenance. Everything checked out ok except for one error message during the volume test as follows:

Catalog File (B-Tree) <Failed. File Thread Mismatch. (-92)>

I ran it again but got the same error code. Should I worry about this? Should I run Disk Utility to fix it or should I use DiskWarrior? Any advice on how to proceed would be much appreciated.

iBook G3/900 14 Dual Boot, Mac OS X (10.3.x), iMac 350 Indigo OS 9.2, PowerBook G4- OS 10.4.11

You should attempt to fix the disk. TT Pro should be able to repair it, but if not you can try using Disk Warrior. Disk Utility may fix it. If the problem cannot be repaired then you will need to reformat the drive and reinstall OS X.

Brian,
Kappy knows better than I, but we used to see many B-tree out of order
errors when people were putting Norton on their Macs. Just follow his
advice . . .

Brian:

Launch Tech Tool Pro.
Then Select Tests and click on the Volumes tab.
Click on the disclosure triangle to show volumes and click on the arrow to begin the tests. When TTP finds the errors the green light at the end of the progress bar turns red and when you get the error message the legend above the bar says Repair. Just click the red arrow to repair.

Thank you both very much for your fast and informative responses.
For some reason TTP wasn't able to repair this error. Maybe my version 4.0.3,
while it works, maybe it is not the best version for Tiger.
On my Panther machine it works fine.

Anyway, I have Disk Warrior but that is version 3.0 and Tiger did not like that.
Luckily I was able to get a free upgrade to 3.0.3 from Alsoft's website
where I was able to burn a bootable CD. This time Tiger took it and DW was able to repair
everything. Great news!

Thank you again. Not only do Macs rock, but this forum and you guys who participate in it are the best!
