  • PrintPrint
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.
