    Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is an emerging technology that provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the Seagate drive monitors prede- termined attributes within itself that are susceptible to degradation over time. S.M.A.R.T. makes a status report available so that the host can prompt the user to back up the drive if self-monitoring determines that a failure is likely.
