[ubuntu] How to share folders not in your home directory

view story

http://ubuntuforums.org – I've got a data drive mounted on my Ubuntu 12.04. I've setup a samba and shared the mounted drive. When I go to my windows machine, I can see the shared drive. But cannot access it. After trying to figure things out, I've found out that if I share a folder in my home directory, I am able to access it from the windows machine without problem. Would anyone know what additional steps I need to perform in order to get this share to work. Thanks in advance. (Hardware)
