[CentOS] How Can I ...

I've got a WD My Passport Ultra 1TB (USB) plugged into my router and I 
have 4 Windows machines, all running Windows 7, and all 4 machines can 
see the device as drive 'Y'. I use this device several ways, i.e. all my 
Windows machines use the same Firefox bookmarks and cookies

I've got 5 machines running CentOS 6 x86_64 and I'd like to know what do 
I have to do for them to 'see' that same 1TB device? Right now I use 
winscp to get the data from CentOS and save it on the device via Windows.
