Problem: The capacity of the hard disk, as indicated by the system, is less than 
the nominal capacity.

Troubleshooting and problem resolution: For computers equipped with the 
OneKey Recovery feature, the system recovery feature needs to occupy some 
hard disk space. This may account for the apparent hard disk capacity deficit.

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).

The capacity of the hard disk shown in Windows can be calculated according to 
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.

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.

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.

Record the following information as it may be useful later when troubleshooting 
system problems:
The drivers for this computer model only support the Windows 8.1 system.
