Handling precautions
Set the drive down gently to prevent damage from impact or vibration.
Handle the drive carefully by the edges. Do not touch the exposed printed circuit board or any electronic components.
Do not press on the top or bottom of the drive.
Before handling the drive, discharge any static electricity from yourself and your clothing. With one hand touch an
unpainted metal surface, then touch the ESD bag with the other hand. Remain in contact with the chassis and the bag
for a minimum of two seconds.
Vibration, shock and static electricity to the drive will damage the precision parts. In particular, prevent vibration or
shock generated by dropping, knocking over or hitting the drive. Also, avoid touching the electrical components
directly, which can discharge electrostatic energy and damage the drive.

Mounting Recommendations
The mounting hole locations and size of the drive are shown below:

The drive will operate in all axes (six directions) and will stay within the specified error
rates when tilted ±5 degrees from these positions. Performance and error rate will stay
within specification limits if the drive is operated in the other permissible orientations from
which it was formatted. Thus a drive formatted in a horizontal orientation will be able to
run vertically and vice versa.
The recommended mounting screw torque is 0.3±0.05 Nm.
The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for
horizontal mounting.
The user is responsible for using the appropriate screws or equivalent mounting hardware
to mount the drive securely enough to prevent excessive motion or vibration of the drive at
seek operation or spindle rotation.

Interface connector
The figure below shows the physical pin location. This connector is identical for 2.5” and
3.5” SATA hard disk drives, therefore the host side cabling is suitable for both form factors.
All pins are in a single row, with a 127 mm (0.050”) pitch.
The comments on the mating sequence in Table in section 7.3 of the Product
Specification Manual apply to the case of back-plane blind-mate connector only. In
this case, the mating sequences are:(1) the ground pins P4 and P12;(2) the pre-charge
power pins and the other ground pins; and (3) the signal pins and the rest of the
power pins.
There are three power pins for each voltage. One pin from each voltage is used for
pre-charge in the backplane blind-mate situation.
If a device uses 3.3V, then all V33 pins must be terminated. Otherwise, it is optional
to terminate any of the V33 pins
If a device uses 5.0V, then all V5 pins must be terminated. Otherwise, it is optional to
terminate any of the V5 pins
If a device uses 12.0V, then all V12 pins must be terminated. Otherwise, it is optional
to terminate any of the V12 pins.
