Abstract: A disk drive unit mounting device is adapted to carry one or plural disk drive units. The mounting device includes a temperature control module and a carrier module secured together y a releasable fastener device so that the temperature control module controls the temperature of the disk drive unit. The temperature control module has an air flow control device for controlling the flow of air across the disk drive unit appropriately according to the required temperature for the disk drive unit. The mounting device may be used in testing disk drive units.

Abstract: A disk drive support assembly has a clamp arrangement for releasably clamping a disk drive to a massive block. The clamp arrangement may be an inflatable actuator that is operable to clamp the disk drive to the block via a disk drive carrier. Various clamp assemblies for clamping a disk drive to a substrate, such as a disk drive carrier, are also disclosed. A disk drive carrier that can be adapted for use with different types of disk drive is also disclosed. Such disk drives include those that provide for electrical and/or data connections under the disk drive, those that provide for electrical and/or data connections at the rear of the disk drive, and those that have their own so-called product card associated therewith.
