A hard disk drive having a disk storing data, a spindle motor rotating the disk, an actuator having two arms disposed at both sides of the disk, and a disk locking apparatus locking the disk not to rotate by closely contacting a side surface of the disk when the disk stops rotating. A suspension supporting a record/reproduce slider is installed at a first arm disposed at one side surface of the disk. The disk locking apparatus is installed at a second arm disposed at the other side surface of the disk. The disk locking apparatus has a dummy suspension whose one end portion is installed at the second arm and has a predetermined elastic force, and a dummy slider installed at other end portion of the dummy slider, and locking a stopped disk to prevent movement of the stopped disk and damage to bearings of the spindle motor.
