Adding or Replacing a Hard Drive in HP Pavilion Elite Desktop PCs

This document pertains only to HP desktop computers with the following types of computer case:

Image of the computer

Before you begin

  • You need a flathead screwdriver.

  • Remove the Pocket Media Drive, if it is present.

  • Turn off the computer. Disconnect the Ethernet or modem cable. Then disconnect the power cord.

  • Move the computer to a clear, flat, stable work surface over a non-carpeted floor.

  • HP strongly recommends the use of an anti-static wrist strap and a conductive foam pad when working on the computer.

  • To add an additional SATA hard disk drive, an additional SATA data cable is required .

  • Do not remove a component from its protective packaging until you are ready to install it.

WARNING: The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
CAUTION: This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a noncarpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.

If you are adding an additional hard drive

When adding a hard drive, it important to identify the connectors on the motherboard.

The hard drive connectors on the motherboard must match the type of hard drive you wish to connect. If your motherboard has SATA data connectors and one is not in use, you can attach an additional SATA hard drive. If your motherboard has an IDE connector available, you can attach an IDE hard drive.

NOTE: If you want to install a IDE hard drive to a motherboard that has only SATA data connectors, a third-party adapter is necessary.

Removing a drive

Use the steps in this section to remove a hard disk drive or to prepare to install a new second drive.

WARNING: Make sure the computer is disconnected from power before starting.
Step 1
Remove the side panel.
For more information about removing the side panel, refer to the HP support document Opening the PC Case .
Pulling the side panel toward the back of the computer to release it
Step 2
Remove the front panel.
For more information about removing the front panel, refer to the HP support document Removing the Front Cover .

Step 8
Lift the cage partially out of the computer.
Lifting the cage partway out of the computer
Step 9
Find the power and data cables at the back of the drive.
Plugs on the drive cables are keyed and can be inserted only when aligned properly to the connector on the drive.
In addition, some plugs have a latch that must be pressed or squeezed to release the plug while pulling it from the connector.

Step 10
Disconnect the power and data cables from the back of the hard drive:
  • For plugs without a latch, pull the plug straight out from the connector.

  • For plugs with a latch, press the latch in the center of each plug (1 or 3), and then pull the plug from the connector (2 or 4).

Step 11
If you are adding a new second drive, skip this step and continue with Installing a drive .
Remove the four screws (two on each side) that secure the drive in the cage.
For a second drive, remove the upper four screws.
