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
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
http://seatools.seagate.com.
