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/ Regards -- Chad M. Gross
