I restarted into OS 9 to do some stuff and when the desktop booted up my OS X partition wouldn't initialize. So I restarted a couple of times to see if that would do anything. It didn't.

I scanned the partition using 9's Disk First Aid and discovered the following errors:

-Mount Check reveals serious errors
-Overlapped extent allocation 4, 3456
-Volume Bit Map needs minor repair 4, 162
-Volume Header needs minor repeair 1,0

As I understand it, if I try and repair these using Disk First Aid I'd
"fix" the drive in the sense that these errors would (most likely) be gone, but because of differences between 9 and X's file structures, etc. I'd probably wipe all the data stored there. Which would not be cool.

So any suggestions on how to fix an X partition while stuck in a barebones install of 9?

I would boot into single user mode. Do this by holding the apple-s until you get to the command line.
Then type in fsck -y if you have journaling on type fsck -yf repeat this until you have no errors. Hope this helps.

There shouldn't be any problem using Disk First Aid, both Mac OS X and Mac OS 9 use HFS+.

You are right though, Disk First Aid certainly doesn't correct a lot of things, in which case you might have to try a product like DiskWarrior

You can also try booting from a Mac OS X install CD and then running Disk Utility from in there and see how far it manages to get.

Hope this helps!

hehe it sounds like OS 9 trashed your hard drive. This happened to me twice with my g4 and is why I haven't used it since.

Get DiskWarrior. That app works miracles.

I didn't think I had an OS X install disk with me but it turns out I did. Disk Utility seems to have fixed everything and I've backed up the HD to my external just in case.

Thanks for the advice.
