Why is the hard drive capacity displayed by the OS be different from its
nominated capacity?
Most users may have discovered that the capacity of a 10GB hard drive
will become 9GB when displayed from the OS; and 20GB become 19GB,
40GB become 38GB..., etc. The bigger the capacity, the bigger the
difference. It is because hard drive makers and OS developers calculate
hard drive capacity in different ways. As a result, the nominated capacity
is different from the exact capacity displayed by the OS.
Calculation of hard drive
capacity by drive makers
1GB=1,000MB
1MB=1,000KB
1KB=1,000 bytes
Example of a 40GB hard drive:
Calculation by drive makers
40GB=40,000MB
=40,000,000KB
=40,000,000,000 bytes
Exact capacity of a 40GB hard drive displayed in the OS:
40,000,000,000÷1024÷1024÷1024=37.2529 (GB).
Furthermore, when you partition a hard drive, the system will reserve
some space on the drive for system files. Therefore, the total capacity of a
hard drive displayed by the OS will never be the same as its nominated
capacity.
I hear noise when connecting an earphone to Joybook.
The instructions below will guide you through the troubleshooting
process.
•
Connect the earphone to other devices, such as a radio to see if you can
still hear that noise. If the noise persists, the earphone may be out of
order.
Calculation of hard drive
capacity by OS developers
1GB=1,024MB
1MB=1,024KB
1KB=1,024 bytes
Calculation by OS developers
40GB=40,960MB
=41,943,040KB
=42,949,672,960 bytes
•
If you can hear the noise only when inserting, it is the result of high
instantaneous current. It is a normal phenomenon.
