3.2.4 S.M.A.R.T. commands
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) pro-
vides near-term failure prediction for disc drives. When S.M.A.R.T. is
enabled, the drive monitors predetermined drive attributes that are
susceptible to degradation over time. If self-monitoring determines that
a failure is likely, S.M.A.R.T. makes a status report available to the host.
Not all failures are predictable. S.M.A.R.T. predictability is limited to only
those attributes the drive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the Draft ATA-4 Standard.
This drive is shipped with S.M.A.R.T. features disabled. You must have
a recent BIOS or software package that supports S.M.A.R.T. to enable
the feature. The table below shows the S.M.A.R.T. command codes that
this drive uses.
