I'm not sure if shutting down smartd really matters unless the drive is 
actively running a test or something.

Modern drives (where "modern" means anything made in the past 10 years I 
think) are set up in such a way that the inertia of the spinning 
platters will 'throw' the heads onto the parking area if power suddenly 
dies. This is not the same thing as intentionally issuing a park-head 
command, but the results are more or less the same.
