Abstract: A verification system including a block gage configured to connect to a voltage source comprising a ground terminal and a positive terminal, and to receive a top cover configured to mate with a base unit for a storage device. The block gage includes a plurality of pins, each of which being configured to: be electrically insulated from each other, form a completable circuit, be electrically connected to the positive terminal, and correspond in location and height to a top cover contact point in the base unit or a keep out point in the base unit. The block gage includes a spring mounted probe configured to be electrically connected to the ground terminal, wherein when the top cover contacts the spring mounted probe and a pin of the plurality of pins, a completable circuit for the contacted pin is completed, thereby indicating that the top cover contacted the contacted pin.
