d700 + 4gb CF phenomenon !!!

Hi guys,

I am having a strange phenomenon with my d700. I got when i purchased the camera, a 4gb CF card ( unknown brand ). when i put it in the cam, formatted it and connect it with the computer, it's showing 1.99 Gb.

I thought it's the CF, since the brand was unknown. I called the dealer, and he agreed to exchange for a kingston 4gb CF.

Now , with the kingston 4gb CF, and after the format, my computer is showing again 1.99 gb. which means that most probably, the cards are not the cause.

Any ideas guys ? do i have to create some folders in-camera ? if yes, how ?
I don't know what to think now, your help will be much appreciated, thanks !!!
