Note. Signal ground on the power control board (PCB) and the
head and disc assembly (HDA) are connected together in
this drive and you cannot separate them. The equipment
in which you have mounted the drive is connected
directly to the HDA and PCB without electrically isolating
shock mounts. Maximizing the conductive contact area
between HDA ground and system ground may reduce
radiated emissions.
If you do not want the system chassis to be connected to
the HDA/PCB ground, you must provide a nonconductive
