2.13.1Free 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 0 G sensor mounted on the printed circuit board assembly (PCBA) to sense this event.

To enable the Free Fall Protection feature on ST9500325ASG, ST9320325ASG, ST9250315ASG, ST9160314ASG, ST9120315ASG and ST980313ASG models, use Set Features command 41h. To disable this feature, use Set Features command C1h.

Information about Free Fall Events that have occurred is available through SMART attribute FEh.

Note. Of the models documented in this product manual, the Free Fall Protection feature is provided only on ST9500325ASG, ST9320325ASG, ST9250315ASG, ST9160314ASG, ST9120315ASG, and ST980313ASG models.
