ST310014ACE Product Manual, Rev. B
3.1.4 S.M.A.R.T. commands
S.M.A.R.T. provides 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
the attributes the drive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the Draft ATA-Rev 6 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST)
S.M.A.R.T. command for D4
The diagnostic software ships with all new drives and is also available at:
http://seatools.seagate.com.
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
this feature. The table below shows the S.M.A.R.T. command codes that
the drive uses.
