I have that drive packed and ready to send.  With Thanksgiving it will 
be next week before I can get someone there to install the drive.  
Nothing in the logs during the writing process, but here is what I see 
when I try to mount the disk.

Nov 23 12:54:28 nevada kernel:  I/O error: dev 0b:00, sector 1696
Nov 23 12:54:28 nevada kernel: Unable to read rock-ridge attributes

Nov 23 12:54:28 nevada kernel: ISOFS: unable to read i-node block

I then reinitialized and wrote a disk without rockridge attributes and 
got this when mounting.
