Before you begin

  • Turn off the computer, disconnect all cables, and transfer 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.
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 is 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 an IDE hard drive to a motherboard that has only SATA data connectors, a third-party adapter is necessary.

Removing the primary disk drive

Use the steps in this section to remove a hard drive so that an empty bay can be used to install a new drive.
WARNING:Make sure the computer is disconnected from power before starting.
Step 1

With all cables disconnected from the computer, remove the right side panel and the front cover.

For more information about removing the right side panel and the front cover, refer to the HP support documents Opening the PC Case and Removing the Front Cover .

Installing a primary disk drive

Use the steps in this section to install a new hard drive into an empty drive bay.
Step 1

The original hard drive is fitted with 4 large-headed screws that fit into slots on the drive cage. If this is a new hard drive, transfer the screws from the old drive to the new one.

Step 2

If you are installing a Parallel ATA drive (IDE flat ribbon cable) check the jumpers on the new drive to make sure they are correct. Normally, the drive should have the jumper set to Cable Select (CS).
Jumpers on the hard drive
Jumper positions can vary from drive to drive. Look for etchings or diagrams printed on the drive for instructions.

Step 3

Match the screws on the drive with the slots in the drive bay. Insert the hard drive into the drive bay until it snaps into place.

Step 4

Connect the power and data cables to the drive. The connectors are keyed and can be attached in only one way.

Step 5

Replace the right side panel and the front panel, and then reconnect the cables.

CAUTION:MBR or NTFS partitions are limited to 2 TB (without using dynamic disks and volume sets). If you are installing a hard drive that is 2 TB or greater, HP recommends formatting the drive using GPT partitions.

Step 6

Perform a system recovery (to replace the original software that came with the computer) or install a new operating system.
