To clarify some things.....
Customer Rating: 




I just wanted to point something out for these kids..
I see like 27 reviews saying.. "I BOUGHT A 20GB HD! OMG ITS ONLY 13GB!! BUT I DELETED EVERYTHING.. WHY?!?!"
Heres the scoop. Theres a thing called format..
It IS a 20GB drive.
You bought a 20GB drive.
1 GB = 1,024 MB
1 MB = 1,024 KB
1 KB = 1,024 Byte
1 B = 8 bits. yes. bits. its different. and small.
1 bit = 2441231532561243 atomic particles... just kidding...
thats the standard..
now they're trying to switch to this... 1000 standard.
Because people cant wrap their brains around the 24 extra on a K and america cant do math..
So a straight K is "easier"
[1000 plus 1000 is 2000...]
heres the exponentiality for the old method:
from the middle..
8mb
16mb
32mb
64mb
128mb
256mb
512mb
1024mb
wait.
1024?
WTZOMG?!
yes.
because the number 8 likes the number 1024..
But they left out one thing!
All our wonderful devices (except any Mac on Snow Leopard) [thanks, Apple, i love you]
are still stuck on the 1,024 idea. the truth.
yeah.
so your hard drive was made to the specifications that 1 GB is equal to 1,024 MB......
Your xbox reads the hard drive according to the specifications that 1 GB is equal to 1,000 MB
for dummies. but your xbox is not a dummy. it knows better and says 13 available..
24 MB difference on the gig...
Example:
Go check out your computer. What size hard drive is in it?
Oh, an 80GB? I bet when you look at total capacity under "My Computer" (for you windows folks)
it'll say something like.... 75.6GB
Did that make any sense?
IT IS A 20GB DRIVE!
just remember. your computer/xbox is working with 8's originally..
