system-absent environments
Towerable Product can be oriented as a tower (in addition to desktop orientation)
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
