 One gigabyte, or GB, equals one billion bytes when referring to hard drive capacity.

2

 G-Force Protection enables the drive to return to a nonoperating state in the event of a drop while reading/writing.

3 

Typical laptops 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.

Seagate offers the industry’s leading
warranty to demonstrate our commitment
to product reliability and our customers’
success. Every Seagate internal hard
drive for PCs, notebook computers and
