Enable or Disable support for the hard disk's S.M.A.R.T.

capability. S.M.A.R.T. is supported by all current hard disks
and allows the early prediction and warning of impending
hard disk failures.
You should enable it if you want to use S.M.A.R.T.-aware
utilities to monitor the hard disk's condition.

class of the SATA controllers and can cause driver reload
in the OS.
