SMART Hard Drive Fault Prediction

The SMART hard drive monitors hard drive activity to predict

failures and, in some cases, fix faults before failures occur.

Fault prediction and failure indication parameters, such as

abnormal variations in spinup and seek times, or non-

correctable read and write errors, are tracked to determine the

hard drive condition. Should these errors become significant,

the workstation displays a warning message. The warning gives

you time to back up the hard drive and replace it prior to

experiencing downtime or loss of data. The Prefailure Warranty

for SMART hard drives allows you to replace these drives, free

of charge, before the drives fail.

SMART hard drives are compliant with the Small Form Factor

Committee Specification for Self-Monitoring, Analysis, and

Reporting Technology (SMART). SMART is the industry

standard technology, pioneered by Compaq and originally called

IntelliSafe, that allows you to prevent data loss and minimize

downtime, in concert with Compaq Management Agents.

The Compaq Drive Protection System (DPS) is a diagnostic tool

built into the hard drives installed in select Compaq Deskpro

Workstations. DPS is designed to help diagnose problems that

might result in unwarranted hard drive replacement. Refer to

Chapter 2, "Software," for more information and instructions on

using DPS.

Ultra ATA Integrity Monitoring monitors the integrity of data

as it is transferred between an Ultra ATA hard drive and the

system's core logic. If the workstation detects an abnormal

number of transmission errors, the workstation displays a Local

Alert message with recommended actions. An alert is also sent

over the network to the system administrator.
