Abstract: A computer disk assembly has a power supply-wiring harness unit and a disk pack unit for housing and mounting a hard disk drive. This disk drive is suspended within its housing on a vibration isolating suspension system which utilizes a plurality of spring steel coils, this suspension system being designed to isolate the disk from external vibrations and shock. The power supply-wiring harness unit is removably connected to the disk pack unit through a fastening system which includes an elongated plate member which slides into a channel formed in the bottom of the disk pack unit and a latching fastener member which is driven by a handle and engages a mating receptacle in the disk pack unit.
