Drive Self Tests (DPS) Drive Protection System (Adaptec and LSI SCSI controllers do not offer DPS)
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 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 (F10 diagnostic access not available with SCSI
drives)
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
Security Features
Access panel key lock
(standard) Prevents removal of the access panel and all internal components including optical and floppy
drives
Padlock (optional) Prevents entire system theft and discourages access panel removal. 7mm diameter padlock loop
at rear of system.
Kensington Cable Lock
(optional) Prevents entire system theft only. 3mm x 7mm slot at rear of system.
Universal chassis clamp
lock (optional) The version without a cable discourages access panel removal and prevents theft of IO devices.
The version with a cable additionally prevents entire system theft and allows multiple systems to
be secured with a single cable.
