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
Table 5
.
2.12 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 “Is my Drive 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.
2.12.1 Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged
within the defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year
packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and
non-corrosive environment). During any storage period the drive non-operational temperature, humidity, wet bulb,
atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
