Ya....  I've had too many "but the drive isn't a brick ... how could it 
be the failure" experiences to use that as my benchmark.  Now, if the 
drive is not doing what it's supposed to do in any (reproducible) 
manner, I consider it a failure.  Well ... almost any reproducible manner.

Ya.  That's where the reproducibility of any given failure comes into play.
