According to the original email, 3 drives are missing from the array. So 
  we now know that one drive is bad.  But what about the other 2?  Is 
the data on them in sync or is it possible that one of them might have 
gotten knocked out of the array many months ago?  mdadm might be smart 
enough to figure it out but I don't know...
