Free Fall Protection feature
The Free Fall Protection feature provides enhanced data protection against shock events that may occur while
the drive is operating. This feature is designed to decrease the likelihood of data loss by detecting a free fall
event and unloading the actuator before a shock takes place in falls of >8 inches (nominal). The drive uses a
0G sensor mounted on the printed circuit board assembly (PCBA) to sense this event.
