I know they are not physically the same, and I know the Duo comes in larger sizes, but my question is this. I have a linkstation live 1tb, it is almost full and I wanted to upgrade to larger one. I have the chance to get a Duo 4tb for a smoking deal. My worry is that it will be completely different. Since its 4tbs does it have 4 different drives or will my data about 2tbs be spread across them evenly. I guess what I am asking is does the 4tbs appear as one big drive? The reason I ask is that I mainly use this to store my home movies, and backed up dvd's. So when I view them I go through my Xbox 360 and now It shows my Linkstation and then in the linkstation I see the folders I made with movies, music and pictures but since I have an attached 2tb usb drive to the Linkstation that appears as a second drive. I want to go to my xbox and see just the linkstation duo and all the folders in it. Any thoughts?
