I have two Supermicro PDSMi MB servers in productions and i am also 
experiencing mysterious disk loses. The system continues to function 
fine, as i am using gmirror, however something strange is going on. 
Sometimes the disks come back, sometimes i need to reboot the system to 
get them back. I am using Seagate ST3160812AS 3.AAE drives. The drives 
reports no SMART errors, and the cables are secure. The drives are 
attached to a hot swap back plane.
