Accessing a USB harddrive over SMB/AFP

I have successfully gotten network access working as well as usb support. My only question now is how can I access the drive from my computer? The drive shows up in the ATV menu and I can access the files over cyberduck. When I try to access the same drive through finder, I can see the volume. Inside the volume are only two folders, but they are empty.

I type this into the “Connect to Server” window:


All other settings are directly from the knowledge base forum.

I can transfer files that are on the ATV drive without issue, so is there a way of doing this with the external hard drive?
