Computer query

[Clint]

I recently purchased a re-conditioned computer through an auction house.
I am not happy with their service. I sent it back due to a fault but they will not acknowledge it. Apparently dept of fair trading do not have jurisdiction so I am stuck with it.
I have however just noticed something which hopefully will get me out on a technicality.
I was sold a Hdd 500Gb. When I go into my computer and right click on the "c" drive it says 450GB.
Is this normal??

Thanks guys

Yes, always the case. There is a disparity between measurements that the OS uses and what the manufacturer uses. Technically, the OS is incorrect (figure is correct, but they are not GB).

Full explanation here, last bullet point http://en.wikipedia.org/wiki/Kilo-

A formatted drive is less than marked.
