Replacing the Hard Drive
This document applies to HP TouchSmart 520 series desktop computers.
Use the steps in this document to help replace a hard drive in your computer. If you want to add a hard drive with more capacity (upgrade), know that you can upgrade to any sized hard drive that meets the connection type in your computer. Most often this is serial ATA (SATA or eSATA). Also know that there are formatting limitations that may be encountered for drives larger than 2 TB. To access all the data on drives larger than 2 TB format the drive using GPT or create multiple partitions smaller than 2 TB.
Before you begin
- You need a Phillips head screwdriver.
- Turn off the computer. Disconnect the Ethernet or modem cable. Disconnect the power cord.
- Transfer the computer to a clean, flat, stable work surface over a noncarpeted floor. HP recommends that you put down a blanket, towel, or other soft cloth to protect the screen from scratches or other damage.
- Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards and other components. HP strongly recommends the use of an antistatic wrist strap and a conductive foam pad when working on the computer.
- Do not remove a component from its protective packaging until you are ready to install it.
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.

Removing the hard drive
Use these steps to remove the hard drive:
To remove the hard drive, first remove the rear cover.
For instructions to remove the rear cover, see the HP support document, Removing and Replacing the Rear Cover .
Loosen the captive Phillips screw that holds the hard drive in place.
Lift the hard drive handle and slide the cage to the side. Then lift it up and remove it from the computer.
Remove the four screws, two on each side of the hard drive cage.
Save the screws for hard drive replacement.
Slide the hard drive out of the cage.
Replacing the hard drive
Use these steps to replace the hard drive:
Before installing a hard drive in the cage, make sure there is a rubber grommet in each side hole of the drive cage.
Install a new grommet into any hole missing a grommet.
To replace the hard drive in the cage, slide the drive into the cage until the screw holes on the sides of the drive and the cage align.
Replace the four screws that fasten the hard drive in the cage.
Find the four tabs on the underside of the drive cage.
Find the slots that the tabs fit into inside the computer.
Align the tabs on the cage near the slots, and then slide the hard drive in until it is secure.
Press down on the cage handle.
Tighten the captive screw to secure the hard drive in the computer.
Replace the rear cover.
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.
