2. The capacity of the hard disk displayed in the system is less than the nominal

capacity

For equipped with One-Key Recovery feature, the system recovery feature needs to occupy some hard

disk space which is invisible in either the operating system or partition utilities such as FDISK, thus the

available hard disk space is less than the actual capacity.

The nominal capacity of the hard disk uses the decimal system of 1000 bytes, while the actual capacity

uses the binary system of 1024 bytes (for example, the nominal capacity 1G = 1000M, while the actual

capacity 1G = 1024M); the capacity of the hard disk shown in Windows can be calculated according to

the calculation method in the following example:

The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000

x1000/ (1024 x 1024 x 1024) = 37G.

If the hidden partition of 3G - 3 x 1000 x 1000 x 1000/ (1024 x 1024 x1024) = 2.79G is subtracted, the

capacity of the hard disk shown in the system can be obtained. The capacity of the hard disk calculated
