1.10 Electromagnetic susceptibility
The drive operates without errors when subjected to the following:
Radiated noise | ≤ 3 volt/meter, 30 Hz to 500 MHz |
Electrostatic discharge* | ≤ 10 KVolts |
Magnetic field strength | ≤ 5 Gauss |
*Electrostatic discharge susceptibility is measured with the drive mounted in a representative computer system (mounted to a ground plane with an earth ground). Discharges are applied to the bezel or other external surfaces on the ground plane.
1.11 Reliability
Nonrecoverable read errors | 1 per 1013 bits read, max |
Mean time between failures | 500,000 power-on hours |
| (nominal power, 25°C ambient tem- |
| perature) |
Contact start-stop cycles | 50,000 cycles |
| (at nominal voltage and temperature, |
| with 60 cycles per hour and a 50% |
| duty cycle) |
Preventive maintenance | None required |
1.12 Agency certification
1.12.1 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.
1.12.2 Electromagnetic compatibility
Hard drives that display the CE marking comply with European Union requirements specified in Electromagnetic Compatibility Directives. Testing is performed to standards EN 50082-1 and EN 55022-B.
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
