Could you please post the results of "smartctl -a /dev/hdX" for your 
hard drive? I am interested to see the SMART information and extended 
attributes (with counters) to see what this drive failure might "look" 
like on the SMART output.

I am working on a large scale disk testing and failure analysis project. 
(Not as large scale as google's, and specific to our usage, but they are 
similar in concept.) Also I do SMART monitoring for my own hard drives 
and in fact it was the SMART hard drives that informed me that the 
internal fans had failed in one of my cases because the drives were 60C 
(way overheated) and claiming they were about to fail.

Thanks a lot,
Jim
