When referring to hard drive capacity, one gigabyte, or GB, equals one billion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage. Quantitative usage examples for various applications are for illustrative purposes. Actual quantities will vary based on various factors, including file size, file format, features and application software.

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 and S4; while in the S3 and S4 states, drive sleep and drive standby modes will not contribute to battery power consumption.

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.
