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
