Adding or Replacing a Hard Drive in HP Pavilion Elite HPE-100 Series Desktop PCs

  • PrintPrint
This document pertains to adding or replacing a hard disc drive in HP desktop computers with the following case:
 HP Elite Desktop PC

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 disc 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.
