A damping structure of a hard disk drive including a damping plate, attached to an upper surface of a cover member, to reduce a noise from an interior of the hard disk drive, and a resilient plate, provided to an edge of the cover member, to alleviate a shock applied to the cover member via resilient deformation of the resilient plate. The resilient plate is bent from the damping plate so as to be spaced apart from the upper surface of the cover member at a desired interval. The resilient plate is provided at a height higher than a protrusion formed along the edge of the cover member. The external shock applied to the cover member can be effectively alleviated, and the resilient plate may minimize a flaw that may be formed on the damping plate in the course of assembling the hard disk drive.
