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 
2.12 Warranty
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.
2.13 Agency certification
2.13.1 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.
2.13.2 Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the 
Electromagnetic Compatibility Directive (2004/108/EC) as put into place 20 July 2007. Testing is performed to the 
levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are defined 
by EN 55022, Class B and the immunity levels are defined by EN 55024.
Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the 
directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. 
The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if 
necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should 
confirm EMC compliance and provide CE marking for their products.
Korean RRL
If these drives have the Korean Communications Commission (KCC) logo, they comply with paragraph 1 of Article 
11 of the Electromagnetic Compatibility control Regulation and meet the Electromagnetic Compatibility (EMC) 
Framework requirements of the Radio Research Laboratory (RRL) Communications Commission, Republic of 
Korea.
