procedure. It produces an evaluation on whether the hard drive is the source of the problem and
needs to be replaced.
The system expands on the Self-Monitoring, Analysis, and Reporting Technology (SMART), a continuously
running systems diagnostic that alerts the user to certain types of failures.

SMART Technology
(Self-monitoring, analysis
and reporting technology -
Windows XP only)
Allows hard drives to monitor their own health and to raise flags if imminent failures were predicted
Predicts failures before they occur. Tracks fault prediction and failure indication parameters such as re-
allocated sector count, spin retry count, calibration retry count.
By avoiding actual hard drive failures, SMART hard drives act as "insurance" against unplanned user
downtime and potential data loss from hard drive failure.
SMART I - Drive Failure Prediction
SMART II - Off-Line Data Collection
SMART III - Off-Line Read Scanning with Defect Reallocation
