Reliability

2.12.1

Annualized Failure Rate (AFR)

The product shall achieve an Annualized Failure Rate (AFR) of 0.62% when operated in an environment of

ambient air temperatures of 25

°

C. Operation at temperatures outside the specifications in Section 2.9 may

increase the product AFR. AFR is a population statistics that is not relevant to individual units.

AFR specifications are based on the following assumptions for DVR/PVR environments:

•

8760 power-on-hours per year.

•

10,000 average motor start/stop cycles per year.

•

Operations at nominal voltages.

•

Temperatures outside the specifications in Section 2.9 may reduce the product reliability.

• Normal I/O duty cycle for DVR/PVR devices. Operation at excessive I/O duty cycle may degrade product

reliability.

The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product

AFR.

Agency certification

2.13.1

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.

2.13.2

Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec-

tromagnetic 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.

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.

Nonrecoverable read errors

bits read, max

Annualized Failure Rate (AFR)

0.62% (nominal power, 25°C ambient temperature)

Contact start-stop cycles

50,000 cycles

(at nominal voltage and temperature, with 60 cycles per hour and a 50% duty cycle)

Warranty

To determine the warranty for a specific drive, use a web browser to access the fol-

lowing web page:

support.seagate.com/customer/warranty_validation.jsp

From this page, click on the “Verify Your Warranty” link. You will be asked to provide

the drive serial number, model number (or part number) and country of purchase.

The system will display the warranty information for your drive.

Preventive maintenance

None required.
