I was thinking about this same question over the weekend. I have no  
idea what the answer is, but am hoping someone has one.

I'm pretty sure an answer exists... I have an Intel motherboard with  
a hardware raid controller. I'm sure the controller knows if a drive  
fails, and maybe even logs the event somewhere... I'm just not sure  
where. I'm going to try digging in the docs for my raid controller...
