During my testing I was fairly reckless and discovered that smartctl 
errors out when you try to do much on a mounted drive ( as it should, in 
my opinion ).  There is a lot of information stored in a SMART hard 
drive, I'd start by dumping that, smartctl -a /dev/hda for example.  
Posting the returned information might be interesting, especially the 
table of stats about 2/3 of the way down.
