1. A method for detecting removal of a data storage device from a system, the method comprising:
determining that an electrically conductive first pin of an electrical connector of a storage device is disconnected from a mating electrical connector by circuitry detecting a voltage drop corresponding to the first pin;
determining at a later time that an electrically conductive second pin of the electrical connector of the storage device is disconnected from the mating electrical connector by circuitry detecting a voltage drop corresponding to the second pin, wherein the second pin is longer than the first pin;
responsive to determining that the second pin was disconnected after a predetermined period of time after determining that the first pin was disconnected, determining that the storage device has been disconnected from the mating electrical connector; and
responsive to determining that the storage device has been disconnected, triggering a data destruction action corresponding to data stored on the storage device.
