Drive Protection System
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
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
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.
