Abstract

An insertion and removal assembly for installing and removing hard drives from an enclosure, such as a computer chassis, is provided. The insertion and removal assembly includes a sliding member configured to receive a hard drive, a lever handle rotatably connected to the sliding member and an attachment wall having a plurality of protrusions defining a plurality of slots, each slot configured to receive one sliding member. A user reveals a slot for accepting the installation of the hard drive in the enclosure by pushing a tab on the attachment wall near a distal portion of the lever handle to release the lever handle and then pulling the lever handle outward exposing the sliding member. A hard drive is inserted into the sliding member and pushed inwardly into the chassis. Conversely, the sliding member can contain a hard drive which is partially ejected by unlatching and subsequently pulling the lever.
