Dummy hard disk drive

A dummy hard disk drive (HDD) comprising:

• at least one magnetic disk mounted to a spindle motor, the spindle motor attached to a base plate, the at least one magnetic disk consisting of a rigid disk smaller than 4 inches in diameter;
• a plurality of magnetic heads each located distally on spring-loaded suspension, each of the spring-loaded suspensions swaged to an E-block, the E-block attached to a pivot bearing, the pivot bearing attached to the base plate, the magnetic heads confined to an arched pathway over the at least one magnetic disk because of the pivot bearing;
• a primary circuit board devoid of an onboard disk drive controller, the onboard disk drive controller is configured to facilitate communication between the dummy HDD and a central processing unit (CPU);
• a plurality of electrical contact points that are configured to electrically cooperate with a plurality of corresponding electrical connectors, the electrical connectors are external to the dummy HDD;
• the primary circuit board possessing a lip that extends at least 3 mm beyond an HDD perimeter defined by an HDD base plate;
• and
• the electrical connectors electrically connected to an external disk drive controller that is adapted to control at least the dummy HDD and a different dummy HDD.
