Sounds like a seriously f*'d up disk, for which there's only one 
soluton: low level formatting.  After that, before storing anything 
on the disk, run Disk 1st Aid, and then Norton, and make sure there 
are no errors at all (let Norton also do its longish media-scan).  I 
just hope you don't have any data on the FW drive that's not 
backed-up...
In my experience Norton is good tool (despite what others report), 
but as soon as it can't repair something and then attempts a second 
time, you're in trouble...

This sure does sound like serious trouble...  Without a root the 
entire disk is unreadble.  Wonder how Norton fixes this -- and I 
wouldn't be amazed if in this case the 'fix' was worse than the 
problem you started out with.  Gosh, what a nightmare scenario. 
Again, I do hope you have good copies of everything...
