US Patent 7460365 Interposer for a drive bay

An interposer apparatus includes a secondary drive chassis including dimensions such that the secondary drive chassis is operable to couple to a drive bay without the use of a tool and be housed in a primary drive housing defined by the drive bay. The primary drive housing includes a first housing volume. A secondary drive housing is defined by the secondary drive chassis, the secondary drive housing including a second housing volume that is smaller than the first housing volume. A secondary drive coupling mechanism on the secondary drive chassis is operable to couple a secondary drive to the secondary drive chassis and in the secondary drive housing without the use of a tool. The secondary coupling mechanism may be activated to release the secondary drive from the secondary drive chassis while the secondary drive chassis is still coupled to the drive bay and housed in the primary drive housing defined by the drive bay. The interposer apparatus may be coupled to a drive bay to allow secondary drives that would not, by themselves, couple to the drive bay in the primary drive housings. The secondary drives may then be released from the interposer apparatus and the drive bay without removing the interposer apparatus from the drive bay.
