The disk drive unit includes a substantially sealed disk drive housing and related circuit board with drive electronics carried by a common rigid chassis. A power connector plug is securely mounted onto the chassis at a rear margin thereof and cooperates with one or more interface connectors to permit simple slide fit installation of the disk drive unit into a computer system cabinet, such as a central processor unit for a computer. In addition, the disk drive unit includes improved shock mounts for supporting the sealed disk drive housing from the rigid chassis. The disk drive unit further includes a floating bushing arrangement for interconnecting the circuit board to the disk drive housing in a manner substantially isolating thermal expansion characteristics of the circuit board from the remainder of the disk drive unit. | |
