Help needed with error message - Catalog B-tree

Can anyone please help me with the following error when I run Norton Diskdoctor on my G3 Imac - OS 9.0?

The error message reads :

A major error was found in a file record the Catalog B-tree
Node 642, record 3
"Fetch Cache" has an incorrect extent lenght.
The Catalog B-tree is a data structure which keeps tracks of where files are stored on your disk.

I have tried fixing this fixing with Norton System 2.00 but no joy.

Any suggestions anyone?

Many thanks

1. Cleanse your hard drive and CD collection of anything "Norton". Do this as violently as possible (Norton CD into the microwave is a popular method).

2. Buy DiskWarrior and run it over your drive. An invalid B-Tree extent is no biggie... just fix it soon.

DiskWarrior is absolutely superb.
