2.11 Electromagnetic immunity

When properly installed in a representative host system, the drive operates without errors or degradation in perfor-

mance when subjected to the radio frequency (RF) environments defined in the following table:

2.12 Reliability - Annualized Failure Rate

The product will achieve an Annualized Failure Rate (AFR) of <1% when operated in an environment of ambient

air temperatures of 25°C. Operation at temperatures outside the specifications shown 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 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 2.9 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 an enterprise application.

2.13 Warranty

To determine the warranty for a specific drive, use a web browser to access the following 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.

Preventative maintenance: none required.
