Drive Specifications
2.11
Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in
Table 4
.
2.12
AFR and Warranty
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, "Environmental
specifications." 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 Environmental specifications on page 18 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:
http://www.seagate.com/support/warranty-and-replacements/
From this page, click on “Check to see if the drive is under Warranty”. Users 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 the drive.
2.14
Agency certification
2.14.1 Safety certification
These products are certified to meet the requirements of UL60950-1, CSA60950-1 and EN60950 and so marked
as to the certify agency.
