Further Technical Explanation: The nominal capacity of the hard disk is
expressed in the decimal system as 1000 bytes. But the actual hard disk capacity
is expressed in the binary system as 1024 bytes (For example, the nominal
capacity 1G is 1000M, while the actual capacity 1G is 1024M).

is expressed in the binary system as 1024 bytes (For example, the nominal
capacity 1G is 1000M, while the actual capacity 1G is 1024M).
The capacity of the hard disk shown in Windows can be calculated according to
the calculations in the following example:
the calculations in the following example:
The nominal capacity of the hard disk is 40G, while its actual capacity should
be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) =
2.79G is subtracted, the capacity of the hard disk shown in the system can
be obtained.
2.79G is subtracted, the capacity of the hard disk shown in the system can
be obtained.
The capacity of the hard disk as calculated using this method may be slightly
different from the actual capacity due to the rounding of totals.
