Abstract: A installation kit for installing a disk drive into a larger disk drive bay includes a form factor adaptor, an electrical connector and a DC cable. The form factor adaptor comprises a pair of side brackets which interengage with a front plate, forming an internal space. The disk drive inserts into the internal space and a clip is used to secure the disk drive in place. The clip interengages with the brackets, and, thus, no fasteners are required to secure the disk drive to the adaptor. The electrical connector is used to interconnect a pin header of the disk drive data port with a card edge receptacle positioned in the disk drive bay.
