So right now I have a 1TB USB drive directly connected to my RPi through a powered USB 3.0 docking station. My RPi is connected to my Airport router via ethernet. What I'm doing currently to add media is disconnecting the drive from the RPi and connecting directly to my desktop to add media. I would like to be able to keep the drive connected to the RPi and add media through the network but I have no idea how to do this. How are most of you doing this?

Thanks in advance!
