Apparatus for mechanically isolating an excitation source, such as a disc drive spindle motor, to reduce the generation of acoustic noise by and to suppress the effects of external mechanical shocks upon a disc drive. The disc drive includes a base deck having a central opening, the central opening having an interior surface. A mechanical isolator formed by an annular ring of compliant material is disposed within the central opening of the base portion so that an exterior surface of the mechanical isolator is connected to the interior surface of the central opening in the base portion. The mechanical isolator further includes a central opening having an interior surface to which an exterior surface of an inner support portion is attached, the inner support portion supporting the excitation source. The mechanical isolator serves to isolate the inner support portion from the base portion of the base deck, damping the transfer of mechanical energy between the base portion and the support portion.
