5.1.4 Removal From Static Shielding Bag
Before removing the drive from its static shielding bag:

Make sure that your work station is properly grounded.

Wear a properly grounded wrist strap with good skin contact.

Avoid contact with any component on the printed circuit board.
After attaching your wrist strap, gently remove the drive from the static shielding
bag.

Handle the drive by the sides only; avoid touching the printed circuit board.

Handle the drive with the printed circuit board facing downward during
installation.

Do not open the drive’s sealed compartment or remove the seals or any labels
from the drive; this will void the warranty.
5.1.5 Moving Precautions
If you need to move your computer, turn off the power to automatically unload the
heads. This helps protect the media and the heads from accidental damage due to
vibration, moving, or shipping.
5.2 Mounting
Use either the four bottom screws or at least four of the side mounting screws to
rigidly support the drive and prevent vibration. Some adaptor frames may not have
the mechanical design structure capable of mounting the drive to meet the specified
shock and vibration requirements.
The hard drive itself does not provide electrical isolation between mounting locations
and drive ground connection. If electrical isolation is required, the system designer or
integrator would be responsible for providing a solution.
5.2.1 Mounting Restrictions
If your system does not support hot plugging (see “Hot Plug Support” on page 20), it
must be turned off and unplugged before installing your hard drive.
5.2.2 Orientation
You can mount the hard drive in the X, Y, or Z axis, depending upon the physical
design of your system. For best results, mount the drive with all four screws grounded
to the chassis. If all four screws are not used, see "Grounding" on page 42.
5.2.3 Screw Size Limitations
The hard drive should be mounted to the chassis using four 6-32 screws.
Recommended screw torque is 5 in-lb. Maximum screw torque is 10 in-lb.
CAUTION: Screws that are too long can damage the hard drive. Hard drive
screw penetration can differ between products depending upon hard drive
design. WD’s minimum design criteria is to always meet the SFF 8301 industry
standard specification. The industry standard as defined in the SFF 8301
specifies a maximum of 3 mm screw penetration, and for a minimum of 2.4 mm
of thread engagement from both the screw and the hard drive.
See Figure 2-1 for allowable fastener penetration for this product family.
