I just recently got a Western Digital My Book Live and I'd like to put OOTP's data folder on it so I can access it from either my desktop or laptop and not have to bother with USB drives (which is what I was doing previously).
I'm using Linux and I have three shares from the network drive mounted as /media/N1, /media/N2, and /media/N3. You can see them in the terminal using ls as such:

I can also access files from them with other programs, such as Amarok (my music player). So, I know they're mounted correctly.
However, OOTP can't seem to find them:
EDIT: I should add that these are samba shares that are mounted with cifs.
