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 ST9200420ASG, ST9160823ASG and ST980813ASG models, use Set Features command 41h. To disable this feature, use Set Features command C1h. Information about Free Fall Events that have occurred are available through SMART Attribute FEh. Note. The Free Fall Protection Feature is provided only on ST9200420ASG, ST9160823ASG and ST980813ASG models. 2.14 Agency certification 2.14.1 Safety certification The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America. 2.14.2 Electromagnetic compatibility Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products. 14 Momentus 7200.2 SATA Product Manual, Rev. E
