why does my hard drive contain less memory than advertised?

Question

i have a 120 gig ipod that i am using as a hard drive. i wiped it clean and says it has 111 gigs under properties. i dont see how 9 gigs can already be used. software and stuff cant possibly take 9 gigs can it? is there some other way to completely wipe this hard drive clean so i can get those 9 gigs back. im not using it for music or need any other functions other than file storage. click wheel and power button, hold button dont even work. i dont need that stuff. and please dont give me a bs response like "you have enough storage already why do you need 9 extra gigs?"
any help would be appreciated

Answer 1

The 9 gigs that are not showing available are what is being used to operate the computer. Windows, drivers, and any other software that is installed takes space to. If you need more space you could always get an external hard drive, I got a 3TB one off Ebay for 150 bucks.

Answer 2

The "software and stuff" most certainly CAN take up 9 gigs. Plus something advertised as 120GB isn't actually 120GB. It's actually closer to 119GB.

Answer 3

Because 1024 bytes is is 1 kilobyte

And not 1000

Therefore 1024x1024x1024x111 = 119,185,342,464 bytes

Answer 4

It's the illuminati.
