None required.
2.13.1
Annualized Failure Rate (AFR)
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of ambient
air temperatures of 25
air temperatures of 25
°
product AFR. AFR is a population statistics that is not relevant to individual units.
AFR specifications are based on the following assumptions for consumer electronics 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 2.10 may reduce the product reliability.
• Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may degrade
• 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 2.10 may reduce the product reliability.
• Normal I/O duty cycle for consumer electronics environments. 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.
The AFR will be degraded if used in a enterprise application.

2.14.2
Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electro-
magnetic Compatibility Directive (2004/108/EC) as put into place 20 July 2007. 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 direc-
tives 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 compli-
ance and provide CE marking for their products.
