Drive Specifications www.seagate.com 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 3897) 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 the following table: Table 4 Radio frequency environments Test Description Performance Reference Level standard Electrostatic discharge Radiated RF immunity Contact, HCP, VCP: ± 4 kV; Air: ± 8 kV 80MHz to 1,000MHz, 3 V/m, 80% AM with 1kHz sine 900MHz, 3 V/m, 50% pulse modulation @ 200Hz B EN61000-4-2: 95 A EN61000-4-3: 96 ENV 50204: 95 Electrical fast transient Surge immunity ± 1 kV on AC mains, ± 0.5 kV on external I/O ± 1 kV differential, ± 2 kV common, AC mains B EN61000-4-4: 95 B EN61000-4-5: 95 Conducted RF 150kHz to 80MHz, 3 Vrms, 80% AM with 1kHz immunity sine A EN61000-4-6: 97 Voltage dips, interrupts 0% open, 5 seconds 0% short, 5 seconds 40%, 0.10 seconds 70%, 0.01 seconds C EN61000-4-11: 94 C C B 2.12 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.
