Abstract
A data storage device has a shock sense indicator disposed within its housing. The shock sense indicator may provide visible, audible, and/or machine-detectable indication of whether the data storage device has been subjected to a physical shock over some threshold. Machine detection of the shock state can be accomplished optically, mechanically, or electrically. A data storage drive has a detection switch that interfaces with a shock detector of a data storage device to ensure that no harmful operation is performed on a data storage device that has been subjected to a physical shock, thereby avoiding potential loss or corruption of data.
