Seagate ST2000DX001 Manual Do Utilizador

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

H

) that eliminates 

unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
