Jeff:

In addition to these fine suggestions I'd recommend that you pay real close
attention to the temperature reading you get from the smartmon utility.  I
dropped the temperature of my hard drive by more than 5 degrees celsius simply
by leaving the side off of the case.  Overheating is the single biggest factor
in early disk drive failure.
