Abstract: A removable hard disk drive mounting arrangement includes structures at the end of a rack that cooperate with structures on the shaft of a pivotal handle to ensure that final insertion of the hard disk drive casing into the rack is carried out in an even manner without excessive force. The mounting arrangement includes two notches at the end of a pivotal shaft of a handle for the casing, and corresponding angles and bent portions of the rack which permit final insertion of the hard disk driving casing into the rack only when the handle is turned from a horizontal to a vertical position.

Abstract: The present invention relates to a grounding structure for an extractable harddisk, including a first conductor bent from an open end of a rack frame of a harddisk box, and a lock head hole and an LED hole made on the conductor; a second conductor and third conductor mounted on the rear side of the first conductor, and the second conductor is vertical to the third conductor; the second conductor is raised on a long frame, and an expansion side is formed between the long frame and the third conductor; the rack frame is set in the retaining rails of a panel by means of the first conductor, and the lock head and an LED is mounted through the lock head hole and LED hole on the first conductor respectively, and the third conductor is screwed with the outer frame of a host unit so as to discharge static from the lock head and LED out of the host unit.
