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 moni-
tors 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.
