1. A storage system, comprising:
- at least a first primary data storage device, wherein operation of the first primary data storage device is sensitive to shocks; and
a controller, the controller including;
a processor, the processor running a vibration detection algorithm; and
a shock sensor, wherein the shock sensor generates an output in response to a shock to the controller, wherein the output of the shock sensor is provided to the vibration detection algorithm, and wherein in response to detecting a shock exhibiting at least a first predetermined characteristic, the controller alters an operation related to the first primary storage device.

Abstract
A data storage system controller having 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 the associated 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 also 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.
