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)
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
Prevents removal of the access panel and all internal components including optical and floppy drives
Prevents entire system theft and discourages access panel removal. 7mm diameter padlock loop at rear
of system.
Prevents entire system theft only. 3mm x 7mm slot at rear of system.
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.
Drive requires screws to attach to bracket, once attached to mounting bracket, it latches toollessly to
