S.M.A.R.T. provides near-term failure prediction for disk 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-5 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4
