| To determine the warranty for a specific drive, use a web browser to access the following | ||
|
| web page: | ||
|
| 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 sys- | ||
|
| tem 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 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.
