Page 4: Explanation Of Hard Disk Capacity
Explanation of hard disk capacity Dear user, While using your computer, you may find that the nominal hard disk capacity indicated is somewhat different from the disk capacity displayed by the operating system. For example, a nominal 80GB hard disk will appear as less than 80GB in the operating system. This discrepancy is not an error in hard disk installation nor any other problem, but a normal phenomenon for computers.
Page 5 X × 0.931 G. II. A portion of the hard disk space is used for specific purposes Lenovo computers may come with preinstalled OneKey Rescue System, so the hard disk has a special portion partitioned before delivery, which is used to store hard disk mirror and OneKey Rescue System program files.
