10.3 Drive mounting
Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure to not physically  distort the 
drive by attempting to mount it on a stiff, non-flat surface.
The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable mounting 
surface stiffness:
where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches or millimeters). 
The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed and evaluating the out-of-plane 
deflection of the fourth mounting point when a known force (F) is applied to the fourth point.
10.4 Grounding
Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which 
the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired fo r the system 
chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive (electrically isolating) 
method of mounting the drive in the host equipment.
Increased radiated emissions may result if the maximum surface area ground connection between system ground and drive ground is not 
provided. This is the system designer’s and integrator’s responsibility.
