Warranty

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

 

access the follow-ing web page:

 

 

 

support.seagate.com/customer/warranty_validation.jsp

 

 

You will be asked to provide the drive serial number, model number (or

 

part number) and country of purchase.

 

 

After submitting this information, the system will display the warranty

 

information for your drive.

 

 

 

 

 

 

 

 

*One Gbyte equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.

**During periods of drive idle, some offline activity may occur, according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

***Typical host systems will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby modes will not contribute to battery power consumption.
