Abstract: The hard drive enclosure contains a casing member where a first rack at a first lateral side has a number of partition plates, each having a number of through holes allowing a rod to pass through. A number of covers laterally arranged in parallel on a front side of the hard drive enclosure, each capable of swiveling around a front axle and engages a rod. A number of levers are pivotally configured adjacent to a back side of the first rack, each engaged by a rod and having a pushing piece. When a cover is pulled outward, a rod is engaged to drive a lever whose pushing piece ejects the hard drive for additional distance.
