Troubleshooting problems with Hard Disks
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, 1000 bytes. But the actual hard disk capacity is
expressed in the binary system as 1024 bytes (For example, a nominal capacity of
1GB is 1000MB, while the actual capacity of 1GB is 1024MB).
The capacity of the hard disk shown in Windows can be worked out according to
the calculations in the following example:
The nominal capacity of the hard disk is 40GB, while its actual capacity
should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37GB.
If the Service partition of 3GB - 3 x 1000 x 1000 x 1000/(1024 x 1024 x
1024) = 2.79GB 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.
