Trying to understand some disk error messages and whether I need to do
any partial or complete reinstalls.
Apologies for this lengthy post but I thought the error messages were
important to include.
I'm new to OS X. And this is the first disk error message I've had in OS
X.
This all happened on my PB G4 Ti w/OS X 10.2.3. The drive is partitioned
with OS X and the OS 9 for Classic on the partition that had the error
messages. There are other partitions for OS 9 and several for docs.
I decided to test booting from the OS 9 partition. So I changed the
startup disk while in OS X and restarted. All was well.
Then when switching back to the OS X partition I went to the Startup
Disk panel in OS 9. It gave me a panel showing both the partitions on
the left and system folders on the right. I hadn't seen that before
since I went from OS 8.6 to OS X. I selected one of the OS X system
folders on the right after hi-lighting the OS partition on the left. In
hindsight in trying this again after the repairs, I should have just
hilited the OS X partition and not any of the system folders.
At any rate, I then restarted and it didn't boot back into OS X but
again into OS 9 and then near end of boot gave a message that a disk was
unrecognizable and did I want to initialize it. I selected cancel and
didn't initialize. I restarted again and same thing happened.
Then I used the OS 9 disk first aid and got the following message:
Checking disk "OS X".
Checking "Mac OS Standard" volume structures.
Problem: Invalid BTree Header, 0, 0
Checking wrapper System file.
Checking "Mac OS Extended" volume structures.

The volume "OS X" needs to be repaired.
I proceeded to repair and got the following report from Disk First Aid:

Repairing the disk.
The volume "OS X" was repaired successfully.
Volume "OS X" had overlapping extents. Two or more files were accessing
the same disk block. Aliases to the damaged files have been created in
the folder "OS X

amaged Files".
Use the Finder's "Show Original" command on the aliases to locate the
damaged files. We do not recommend opening the original files.
Instead, the original files should be deleted or replaced from backups.
There were two files in the Damaged Files folder:
One called: Apple File Service Erro #1C241.03 1
I was able to find its original and deleted it.
The other was called: system.log
That one I couldn't find the original, the path said it was in a folder
named "private" but there were no folders visible in that partition with
that name.
I then ran DiskWarrior. It didn't find any problems.
So, trying to figure out:
What caused the problem?
Is it totally repaired?
Should I try to find this other damaged file?
Thank you for any education and suggestions. Appreciate the help.
