heres my situation. I had 2 different 1.5tb external drives and both worked fine on the 360. One hard drive bit the dust so i decided to move everything onto a big 3.0tb drive. however that new drive, when connected to the 360 WILL NOT read! the old, still working will read and of course the broken on will not. but why cant i get this new drive to read? must there be some special file put on there? or what?
