Note.
At power-on, or after a hardware or software reset, the default
values of the features are as indicated above.
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-5 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST
S.M.A.R.T. command for D4
H
) that eliminates unnecessary drive returns.
The diagnostic software ships with all new drives and is also available at:
http://seatools.sea
gate.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.
