One of the first things you can do is install sysutils/smartmontools.
This package gives you the ability to access the S.M.A.R.T.
functionality of your drives. Of course, your drives need to include
S.M.A.R.T.  capability and be enabled. After installing you can check
to see if your drives support it by using the smartctl command. This
is also the command that will use to run tests and check the results.

Check out their homepage for more info: http://smartmontools.sourceforge.net/
