Drive Protection System

SMART Technology (Self-Monitoring, Analysis and Reporting Technology)

SMART I - Drive Failure Prediction

SMART II - Off-Line Data Collection

SMART III - Off-Line Read Scanning with Defect Reallocation

SMART IV - End-to-End CRC for hard drives

Running independently of the operating system, it can be accessed through a Windows- based diagnostics utility or through the computer's setup 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

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

IOEDC: I/O Error Detection Circuitry

Detects errors in Read/Write buffers on HDD cache RAM

Interface in F10 setup provides confirmation of SMART IV support.
