120GB Hard Drive Showing Up as 111GB

I just installed a new 120GB hard drive. When I go to my computer and
highlight the drive, it shows its capacity as 111GB. My other drive is a
40GB one and shows up as 37.2GB, so I know you lose a bit but 9GB seems a
bit excessive.

Can anyone advise please.

Cheers.

There are two definitions of a KB (that's kilobyte). A hard drive
manufacturer defines it as 1000 bytes, but computers defines it as
10000000000 binary, convert that to decimal you get 1024.


Manufacturer Sizes
--------------------------

Kilobyte (KB) = 1000 bytes
Megabyte (MB) = 1000KB
Gigabyte (GB) = 1000MB

Actual Sizes
-----------------

Kilobyte = 1024 bytes
Megabyte = 1024KB
Gigabyte = 1024MB

Now look at the maths below

A manufacturer's GB = 1000x1000x1000 = 1,000,000,000 bytes

A real GB = 1024x1024x1024 = 1,073,741,824 bytes

The manufactur 120 GB =1000x1000x1000x120=120000000000 bytes

to the computer 120 GB should be 1024x1024x1024x120=128849018880

now to see what your computer will say about your 120GB drive her is the
math

1000x1000x1000x120÷(1024x1024x1024)=111.7587089538 57421875 GB

You can work out the true capacity of any drive by using this simple
formula

Why does it - it's exactly right. If you 'lose' 3GB from a 40GB drive, and
120 is 40x3, surely it stands to reason that the 'loss' would be multiplied
by 3 too? And you haven't lost it - in order to lose something, you would
have to have had it in the first place - and you didn't, it just looks as
though it's missing because of the differing definitions of a kilobyte.
