Drive Self Tests (DPS)

Drive Protection System

A diagnostic hard drive self test. It scans critical physical components and every

sector of the hard drive for physical faults and then reports any faults to the

user.

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.

DPS Access through F10 Setup

during Boot

SMART Technology*

(Self-Monitoring, Analysis and

Reporting Technology)

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

* NOTE

: This feature is inoperable when a RAID (Redundant Array of Independent Disks) configuration is enabled.
