Drive Self Tests (DPS)*
DPS Access through F10 Setup during
Boot
• 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
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
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
* NOTE: This feature is inoperable when a RAID (Redundant Array of Independent Disks) configuration is enabled.
