One of my external HDDs has stopped working and I'm looking to replace it. I have seen this and would like to know; can access it over ethernet and USB at the same time? My reasoning for this is to have ethernet access to the PC and have the USB plugged into the back of my 360, so it becomes a removable drive and allows me to access my music and what ever without using pendrives/DVDs or relying on my PC being turned on to stream from.
