●HP has provided four extra 6-32 silver mounting screws installed next to the hard drive bays (1). The mounting screws are required for hard drives installed in the upper (secondary) hard drive bay. If you are replacing a primary hard drive in the lower bay, remove the silver and blue mounting screws from the old drive and install them in the new drive.

CAUTION: To prevent loss of work and damage to the computer or drive:

If you are inserting or removing a drive, shut down the operating system properly, turn off the computer, and unplug the power cord. Do not remove a drive while the computer is on or in standby mode.

Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.

Handle a drive carefully; do not drop it.

Do not use excessive force when inserting a drive.

Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.

If a drive must be mailed, place the drive in a bubble-pack mailer or other protective packaging and label the package “Fragile: Handle With Care.”
