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 imple-
mentation, see the Draft ATA-6 Standard.
