VERY INTERESTING!!!

We had a similar episode with an IBM Shark (I believe) machine. It said 
that two drives failed simultaneously,. The first time required a 
complete rebuild. The second (in 3 months) got IBM's attention. The 
problem was with the controller. We wound up needing to replace the 
controller and then discovered that neither drive was actually bad.

Ooops.
