External Drive Corruption?

I have been importing my music collection - all from cds - to an external firewire (500GB Lacie Big Disk Extreme). I have about 250GB of music on the drive, and so I'm very concerned about the following being a possible corruption.

While importing using itunes, I started to get an error -36 more and more often, so I checked the drive in Disk Utility. The drive is titled "Music Disk" and when I ran a verification with Disk Utility, the following occurred:

Verify Disk -->

Verifying disk "MusicDisk".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking Catalog hierarchy.
Checking volume bitmap.
Checking volume information.
Volume Header needs minor repair
The volume MusicDisk needs to be repaired.
Verify completed.

Repair Disk -->

Repairing disk "MusicDisk".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking Catalog hierarchy.
Checking volume bitmap.
Checking volume information.
Volume Header needs minor repair
Repairing volume.
The volume MusicDisk was repaired successfully.
Repair completed.

--To check, I ran another verification and nothing changed:

Verifying disk "MusicDisk".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking Catalog hierarchy.
Checking volume bitmap.
Checking volume information.
Volume Header needs minor repair
The volume MusicDisk needs to be repaired.
Verify completed.

Repairing disk "MusicDisk".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking Catalog hierarchy.
Checking volume bitmap.
Checking volume information.
Volume Header needs minor repair
Repairing volume.
The volume MusicDisk was repaired successfully.
Repair completed.

--Then I tried repairing again and this happened:

Repairing disk "MusicDisk".
Checking HFS Plus volume.
Overlapped extent allocation (file 3d)
Overlapped extent allocation (file 3d)

Overlapped extent allocation (file 3d)
Overlapped extent allocation (file 3d)
Overlapped extent allocation (file 3d)
Invalid extent file PEOF
Volume check failed.
Repair completed.

I immediately ejected the disk and rebooted from a Disk Warrior 3.0 cd - being that it was the only thing I could think of to do - but DW was unable to rebuild the directory: "The disk is still in use. Quit all other applications, or restart from the disk warrior cd, and then try rebuilding again (2153, 2658).

--Something is definitely wrong here, isn't it? Restarting from the disk warrior cd is what I did, so the disk can't be in use.

I have no idea what's going on here. Please help.

Some other notes: I used Disk Warrior to format the Lacie Drive when I started using it, so I was thinking that might be the root of this problem, though I doubt it. Also, I read on some forums about a bug when using Panther with some firewire drives, but I'm running OS 10.2.8

Also, there's a Disk Warrior update available (3.0.2) but it's not available for download, so I ordered the cd, but I'd rather get to the bottom of this before waiting for the update only to realize that's not the issue.

Any and all help here would be very much appreciated. Thanks.

Well <Restarting from the disk warrior cd is what I did, so the disk can't be in use.> it is if you didn't unmount the volume from the finder, cause then OS X didn't see that you stopped its in use status, so I say make sure it's unmounted next time 'round

I "ejected" the drive from the finder by control/clicking --> eject

Is that no the same as "unmounting"?
