The results of a calibration can be stored in a hard disk drive along with a hard disk condition indication. In one example, the container includes an upper portion having a finish defining a longitudinal axis and an opening into the container. The core layer comprises a material selected from the group consisting of an inherently conductive polymer, an inherently conductive polymer blended with a non-conductive matrix polymer, a conductive filler blended with a non-conductive matrix polymer, and mixtures thereof. The piezoelectric layer is configured to displace within the interior cavity and generate a voltage differential between the first electrical conductor and the second electrical conductor. The cooling system includes at least one oscillating, mechanical component which oscillates at a frequency different from the at least one of the support and detection system.
