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 IV 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
