Hi all. Trying to set up a network drive for my family to be able to use. I am using a Cisco Linksys E3200 Router (if that is important). My question is what filesystem should the hard drive be in order to make sure that I (using Lion), my mother and brother (using Snow Leopard), and my father (using Windows XP) are all able to read/write etc. I have googled extensively to no avail so I figured I'd ask you intelligent people. Thanks!
