[ubuntu] Single Board Computer HD Sharring

view full story

http://ubuntuforums.org – I recently got a SBC(PCI interface) to run in my tower so two people could be using our computer at the same time. I have ubuntu 9.04 on main computer and 9.10 on the SBC. Everything is running alright but what I want to know is if it is possible to share a HD between the two systems. Not the drives with the OS's but if i put in an additonal HD for simply file storage is it possible for that HD to be plugged into the main backplane and then somehow accessed through my SBC? So that files can be shared between the two without transfering to some form of external media and transfering it over? My end goal is to be able to share files between the two, since their in the same tower and connected in hardware i figured there has to be a way to do this? My computer knowledge is higher-intermediate i'd say. I'm a recent linux convert so i'm more familiar with windows but i'm learning quick. I am comfortable with command line and c coding. thanks!
