I have a MicroNet 500GB external drive with 256.05GB available connected to a Dual G5 PM connected via FW800. I've been using for a few years as my iTunes library. It's been having issues where it locks up sometimes, or seems to be running slow.

I tried doing repairs with Apple's Disk Utility and got this message:

Verify and Repair disk “Music”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link
Rebuilding Catalog B-tree.
Invalid node structure
Invalid record count

The volume Music could not be repaired.

Error: The underlying task reported failure on exit

1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired

Any ideas/suggestions? Thanks!

Backup now! Your drive is dying. Don't use it for anything else except the backup.

Disk Warrior is a good bet to fix it up. I'm not sure if the drive is dying, but the directory tree has significant damage - you will certainly lose some data if you keep using it. So I second ibook_steve's advice to back up NOW. Then let DW fix the drive, or reformat it, or replace with newer/bigger/faster drive.
