Right. I'm already chasing down another drive for the replacement. I'm 
not to worried about this server. I could loose all the data, and not be 
put out more than an hour or so of work. What I'm more interested in is 
the Unknown_Attributes that are showing up (and the 3ware to linux 
device question below too). Looking into it a little more, I have a 
number of unknowns.

All 12 of my disks ahve these "Unknown_Attribute"s, and the FAQ 
suggested I asked this list to try and figure them out. These are 
brand-new Seagate disks.
