5 years on distribution units.

 

 

Important: When returning a drive for warranty support, if possible, you should

 

 

provide the valid ATA Master password, or return the drive in the Security Erased

 

 

state with the User Data Area accessible.

 

 

If these recommendations are not followed, Seagate cannot access the drive to

 

 

perform failure analysis to verify your warranty claim.

 

 

To determine the warranty for a specific drive, use a web browser to access the

2.14Agency certification

2.14.1Safety certification

The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America.

2.14.2Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec- tromagnetic Compatibility Directive (89/336/EEC). 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.

Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. 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.
