Handling precautions  
ƒ Set the drive down gently to prevent damage from impact or vibration.  
ƒ Handle the drive carefully by the edges. Do not touch the exposed printed circuit board or any electronic components.  
ƒ Do not press on the top or bottom of the drive.  
ƒ 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.  
ƒ 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.

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  
ƒ All pins are in a single row, with a 127 mm (0.050”) pitch.  
ƒ The comments on the mating sequence in Table in the section 7.3 apply to the case of  
back-plane  
ƒ 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.  
ƒ There are three power pins for each voltage. One pin from each voltage is used for  
pre-charge in the backplane blind-mate situation.  
ƒ If a device uses 3.3V, then all V33 pins must be terminated. Otherwise, it is optional  
to terminate any of the V33 pins  
ƒ If a device uses 5.0V, then all V5 pins must be terminated. Otherwise, it is optional to  
terminate any of the V5 pins  
ƒ If a device uses 12.0V, then all V12 pins must be terminated. Otherwise, it is optional  
to terminate any of the V12 pins.
