DiskWarrior

DiskWarrior is the utility you need.

Yes, DiskWarrior in my experiences doesn't seem to care about OS9 or OSX, but rather HFS+. It has saved me on a number of occasions.

Diskwarrior is one app i never tried, I think it's on my Systemworks CD, but a drive recovery edition. So it fixes problems in the X system as well?

Sure drive 10 can fix things, but I spent 7.5 hours doing so. You could boot to os9 and use diskwarrior and be back in service in about 10 minutes. ...

i haven't had a problem that either diskwarrior or techtool pro couldn't fix in the last 10+ years. i have never run across a problem that had to be resolved by reformatting since about os 2. i've been using macs for nearly 20 years and reformatting is for windows, not macs.

In my humble experience DiskWarrior is king. ...

My Flatpanel original 700mhz machine is freezing every time I start it up. It all started with the OS upgrade to 10.2. I've tried everything from DiskWarrior to Norton to the Disk Utility. I've even checked the ram in OS 9 with a memory tester. The memory checks out as ok. ...

i agree that diskwarrior and plus optimizer are generally better apps and i am looking forward to their os x release soon. ...

I find DiskWarrior 2.1 to be superb for OSX disks. Why would I need aything else? ...
