Time Capsule and USB Hard Drive Problem

I have setup my Time Capsule, gone through the manual setup and allowed disk sharing. My problem is when I connect a USB hard drive to my time capsule it does not show up when I browse the network. I am connected to my Time Capsule (command K, browse server network, connected to Time Capsule), and if I go into Airport utilities and the disk options my USB drive shows up, it just won't pop up when I browse the server and go into the network folder. Am I missing something here? Is there an option I have de-selected or a port needed to be opened? Any help would be appreciated.

I figured out my own question. I didn't know that anything connected to the Time Capsule was a guest disk (duurrrrrrr) and changing it from Not Allowed to Read and Write worked perfect.
