Summary:An apparatus for fixing the spindle assembly in the base of a hard disk drive includes a supporting device positioned on an outer periphery of a round hole formed in a bottom surface of the base. The supporting device has a strip-shaped protrusion over the bottom surface of the base that directly contacts the hub of the spindle motor assembly to the base of the hard disk drive. This concentrates the forces to a smaller area and better secures the spindle motor assembly to the base of the hard disk drive.
