An apparatus and method for mounting a shock sensor to the printed circuit board (PCB) of a disc drive are provided. In particular, the present invention allows the shock sensor to be mounted at any location on the printed circuit board rather than being limited to placement adjacent a mounting screw. The present invention includes a clamping mechanism for rigidly clamping the PCB to the head disc assembly (HDA) so that any shock is properly transmitted from the HDA to the PCB and then to the shock sensor. In one exemplary embodiment, the PCB is clamped between a shield and the HDA. The shock sensor is then position near the point at which the PCB is clamped so that the point of clamping provides transmission of any shock in the Z-axis to the shock sensor. Shocks in the X-Y axis direction are transmitted via the normal mounting screws.

A device for detecting an actuator assembly parking error when a disc drive is powered on includes a magnetic latch attached to the actuator assembly and a latch pin assembly electrically connected to a base plate in the disc drive, where the latch pin assembly is positioned to contact the magnetic latch only when the actuator's read/write head is positioned over a parking zone on the disc. A detection module is electrically connected to the magnetic latch and thus is able to detect whether or not the magnetic latch is contacting the latch pin assembly when the disc drive is powered on. A method for detecting an actuator assembly parking error includes powering on the disc drive, determining whether the magnetic latch has electrical contact with the latch pin assembly, and reporting a parking error if the magnetic latch does not have electrical contact with the latch pin assembly.
