Dunno, but they did, altho the disks back were 'recertified', not new.  As to 
the 1M MTBF rating, I also dunno.  I got 9 're-certified SD drives' back from 
WD and 2 of them (oops, make that 3 of them) have failed in the past 24 
hours, which points to some underlying problem in the system.  It's on a UPS 
which should condition the voltage. The drives that went out were on 
different ports and one of them was direct-connected, not via a hotswap cage 
(due to previous suspicions about the hotswap cage).

Any insight into this failure rate would be appreciated.  About to open 
another support call to 3ware...

I guess I'm the reason they say YMMV. :)

It sounded like his problem was a one-off change in structure which the gui 
was well suited for. 

Unless you're going to script it into maint mode, the gui seems to have 
benefits.
