Installing an Internal 3.5-inch Hard Drive

NOTE: The system does not support Parallel ATA (PATA) hard drives.

1.Remove/disengage any security devices that prohibit opening the computer.

2.Remove all removable media, such as compact discs or USB flash drives, from the computer.

3.Turn off the computer properly through the operating system, then turn off any external devices.

4.Disconnect the power cord from the power outlet and disconnect any external devices.

CAUTION: Regardless of the power-on state, voltage is always present on the system board as long as the system is plugged into an active AC outlet. You must disconnect the power cord to avoid damage to the internal components of the computer.

5.Remove the access panel.

6.Install the four guide screws (two on each side) that were removed from the old drive into the new drive. The screws help guide the drive into its proper position in the bay. Extra guide screws are provided on the exterior of the hard drive bays.

Figure 2-30Installing Hard Drive Guide Screws

NOTE: The hard drive uses 6-32 isolation mounting guide screws. Four extra guide screws are installed on the exterior of the hard drive bays. The HP-supplied isolation mounting guide screws are silver and blue. Refer to Installing and Removing Drives on page 22 for an illustration of the extra 6-32 isolation mounting guide screws location.

If you are replacing a drive, transfer the guides screws from the old drive to the new one.
