3.7.3 Hard drive S.M.A.R.T. function support
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a diagnostic
tool for hard drives to give advanced warning of drive failures. S.M.A.R.T.
provides users a chance to take actions before possible drive failure.
S.M.A.R.T. measures many attrib utes of the hard drive all the time and determine
the hard drives which are close to failure. The advanced identification of possible
hard drive failure s can allow users to back up hard drive or replace the hard
drive.
The “S.M.A.R.T.” function will displ ay S.M.A.R.T. information of hard drives. The
number value is the current value and the number in parenthesis is the threshold
value. The threshold values of hard drive vendors are different; refer to vendors’
specification for details.
S.M.A.R.T. informa tion is only supported on SATA drive. SAS drive does not
have S.M.A.R.T. information. It will show N/A in this web page.
