Adding shows from network drive under Debian package

[malthem]

I have a 2 drive NAS running the Debian Sickbeard package, installed to the first drive (Volume_1). I am trying to add an existing show, which is stored in a folder on the second drive (Volume_2). However, I can only browse folders held on Volume_1 using Sickbeard. I'm completely new to linux, and have had a good look but haven't come up with anything in the way of tutorials. Would it be a big/complicated job for a beginner to change things so that the volume can be accessed? If not, any advice would be appreciated. Cheers!
