Hard drive S.M.A.R.T.
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a diagnostic tool for
hard drives to deliver warning of drive failures in advance. S.M.A.R.T. provides users
chances to take actions before possible drive failure.
S.M.A.R.T. measures many attributes of the hard drive all the time and inspects the
properties of hard drives which are close to be out of tolerance. The advanced notice of
possible hard drive failure can allow users to back up hard drive or replace the hard drive.
This is much better than hard drive crash when it is writing data or rebuilding a failed hard
drive.
“S.M.A.R.T.” can display S.M.A.R.T. information of hard drives. The number is the
current value; the number in parenthesis is the threshold value. The threshold values from
different hard drive vendors are different; please refer to hard drive vendors’ specification
for details.
