Disclosed herein are disk drives and mobile host devices that include a resetable shock sensor. A mobile host device may include a memory device configured to receive a shock event signal and a shock sensor. The shock sensor may be coupled to the memory device and is configured to generate the shock event signal. The shock sensor includes a fixed portion, and a movable portion responsive to shock events. The movable portion is configured to remain out of contact with the fixed portion until the mobile host device is subjected to a shock event greater than a predetermined magnitude and to contact and remain in contact with the fixed portion and to generate the shock event signal after the mobile host device is subjected to a shock event greater than the predetermined magnitude.
