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 | ||
|
| 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 war- | ||
|
| ranty 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 notebooks 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.
