C Drive Protection System (DPS) The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some computers. 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 a service provider for a replacement hard drive. Accessing DPS Through Computer Setup When the computer does not power on properly you should use Computer Setup to access the DPS program. To access DPS, perform the following steps: 1. Turn on or restart the computer. 2. When the F10 Setup message appears in the lower-right corner of the screen, press the F10 key. NOTE: If you do not press the F10 key while the message is displayed, you must turn the computer off, then on again, to access the utility. A choice of five headings appears in the Computer Setup Utilities menu: File, Storage, Security, Power, and Advanced. 3. Select Storage > DPS Self-Test. The screen will display the list of DPS-capable hard drives that are installed on the computer. NOTE: If no DPS-capable hard drives are installed, the DPS Self-Test option will not appear on the screen. 4. Select the hard drive to be tested and follow the screen prompts to complete the testing process. ENWW Accessing DPS Through Computer Setup 59

Drive Protection System (DPS)
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some
computers. 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 a service provider for a replacement hard drive.
