Abstract
A data storage system with a controller that receives shock data from a shock detection sensor and methods utilizing such a controller are provided. The data storage system controller receives information or signals regarding shock events from a shock sensor, enabling the data storage system controller to take remedial action. The particular remedial action taken may be dependent on the severity of the detected shock event. The data storage system controller may receive information regarding shock events from shock sensors provided separately from the data storage system controller, allowing the data storage system controller to take remedial action that is tailored to the locale of a shock event.
