3.2.4 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-4 Standard.
These drives are 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 these drives use.
Note. If an appropriate code is not written to the Features Register, the
command is aborted and 0x04 (abort) is written to the Error
register.
