Additional Features Description
Tower Orientation Product can be oriented as either a desktop (horizontal) or a tower (vertical) for
Tower, SFF, and Mini only. SFF/Mini requires optional stand.
Drive Lock Implementation of the industry standard ATA Security feature set. When enabled, it
prevents software access to user data on the drive until one or two user-defined
passwords are provided.
Boot Sectors Protection MBR and GPT sectors of the hard drive are critical to booting the operating system. By
saving the MBR or GPT data (depending on the how the OS was installed), the BIOS will
be able to monitor for changes and allow the user to override them with the backup
copy at boot-up.
Drive Protection System DPS Access through F10 Setup during Boot (for SATA hard drive only)
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) Allows hard drives to monitor their own health and to raise flags if imminent failures
were predicted
SMART I - Drive Failure Prediction Predicts failures before they occur. Tracks fault prediction and failure indication
parameters such as re-allocated sector count, spin retry count, calibration retry count
SMART II - Off-Line Data Collection 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 III - Off-Line Read Scanning with
Defect Reallocation IOEDC: I/O Error Detection Circuitry
SMART IV - End-to-End CRC for hard drives Detects errors in Read/Write buffers on HDD cache RAM
