Note.
At power-on, or after a hardware or software reset, the default values of the features are as indicated
above.
4.3.3
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-8 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.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.
Note.
If an appropriate code is not written to the Features Register, the command is aborted and 0
x
04 (abort)
is written to the Error register.
