Drive Specifications
2.10.1 Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this
process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-
7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of
tone ratios according to Annex D of the ECMA-74 standards.

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

2.12 Reliability - Annualized Failure Rate
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of ambient
air temperatures of 25°C. Operation at temperatures outside the specifications shown in
air temperatures of 25°C. Operation at temperatures outside the specifications shown in
increase the product AFR. AFR is a population statistic 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
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.
