Abstract
Detecting an impact of an electronic device, such as a data storage device (DSD). An acceleration input is received indicating an acceleration of the electronic device and it is determined whether an acceleration change value based on the acceleration input is greater than an absolute threshold. If so, an acceleration change ratio is calculated using the acceleration change value and an average of acceleration change values. The acceleration change ratio is compared to a relative threshold and it is determined that an impact of the electronic device has been detected if the acceleration change ratio is greater than the relative threshold.
