Wondering if anyone knows a workaround for this problem...

During an OS X upgrade to 10.2.5 via software update, my system hung
when it did the mandatory reboot. The white screen (grey apple) had
the spokes going round and round, so it was in a hung state. Disk
stopped chattering as well.
Not sure how the corruption occured.

Anyhow, I tried a few things, getting it into single user... trying to
clean it or trick it into booting. Tried booting off CD and fsck'ing
the drive.

The message is "invalid catalog record type" which comes back during
the fsck, but it won't fix it.

you have directory corruption that fsck will not fix. get diskwarrior,
which more htan likely will fix things.

you may not need to reinstall - depends how trashed the drive is.
diskwarrior will list everything it does, and you can decide if a
reinstall would be a good idea. it probably is a good idea, but its
also a pain in the butt.

usually diskwarrior will repair a drive fairly quickly, but if the
drive is seriously corrupted, it could take hours, sometimes even
longer. be patient, and make a backup when its done:)

I did solicit help from apple and while the person wasn't any more
technical than I (I was a unix sa in the past), she did have access to
their knowledge base.

She told me that re-installing the OS via the cd repair utility won't >overwrite user data. I believed her, and thought that was the way to
go. Heck that even works in NT when you blue-screen every week so, it
should go even cleaner with OS X, right? Well, in theory. When it
gets to the window where you pick available devices, my drive is not >available. There was a button on the right to attempt repair, but it
did not work (probably runs fsck).

Any ideas on workaround? I know my files are available because when I >mounted it read only, I was able to see my data.

Thanks,
Steve

Somehow that update is a killer.

fsck won't repair a disk with permanent data loss. With any luck your
damage is related to a recently modified system file. Try deleting:

/System
/mach_kernel
/mach.sym
/private
/'Desktop DB'
/'Desktop DF'
/.DS_Store
/Volumes
/cores
/bin


Now run fsck again. With luck, the bad catalog record will no longer be associated with a used portion of the disk. fsck will then be able to
delete the corrupted record. If that doesn't work you'll need to
purchase one of the disk tools mentioned in another part of this thread.
They have the brains to know exactly which files have been damaged and
how to deal with them.

Either way, you're stuck with a clean install of OS X.

Kevin, thanks I'll try this first. Clean install is no problem since
it's not supposed overwrite user files (I hope :-). Just hope I can
get there.

I don't think the drive is trashed at all, it's only one thing that
fsck can't fix as far as I can see...

I've thought about these types of products, but can diskwarrior work
if you can't boot and install software in the normal manner. I.e.
does their cd have a boot/repair utility?

DiskWarrior 3.0 is shipped on a 10.2 boot CD.

Thanks for the help earlier- I also found the answer to my own
question about diskwarrior having a bootable cd...

Question, or pointer to faq or web link:

Is there a list of the various hold down key combos used
while booting for diags? Obviously, command+s for single user
mode but there are quite a few others.

Thanks,
Steve

This one isn't complete, but has a bunch of the common ones:
