Abstract

A disk drive is disclosed comprising a disk, a head actuated radially over the disk, and control circuitry including a shock detector. The control circuitry is operable to detect a resonant frequency amplitude (RFA) of the shock detector, adjust the shock detector in response to the RFA, and take protective action in response to the shock detector.
