When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB,

equals one trillion 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 func-

tions, and thus will not be available for data storage. Seagate reserves the right to change, without notice,
