Drive Protection System (DPS)
Introducing the Drive Protection System
The Compaq Drive Protection System (DPS) is a diagnostic tool
built into the hard drives installed in select Evo Desktops and Evo
Workstations. DPS is designed to help diagnose problems that might
result in unwarranted hard drive replacement.
When these systems are built, each installed hard drive is tested using
DPS, and a permanent record of key information is written onto the
drive. Each time DPS is run, test results are written to the hard drive.
Your service provider can use this information to help diagnose
conditions that caused you to run the DPS software.
Running DPS will not affect any programs or data stored on the hard
drive. The test resides in the hard drive firmware and can be executed
even if the computer will not boot to an operating system. The time
required to execute the test depends on the manufacturer and size of
the hard drive; in most cases, the test will take approximately two
minutes per gigabyte.
Use DPS when you suspect a hard drive problem. If the computer
reports a SMART Hard Drive Detect Imminent Failure message, there
is no need to run DPS; instead, back up the information on the hard
drive and contact your Compaq service provider for a replacement
hard drive.
