Reliability
2.11.1
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The product shall achieve an Annualized Failure Rate (AFR) of 0.62% when operated in an environment of
ambient air temperatures of 25
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 2.8 may reduce the product reliability.
• Normal I/O duty cycle for PVR/DVR 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
2.12.1
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.
2.12.2
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.
