Far as I know, only supports FAT32 drives up to 2TB, I have on my xbox360 hd250GB internal and external 2TB full of titles.I'm also the HD3TB trying to solve my problem.
So the topic.
How did you insert a hd3TB to your xbox360?
Brand, model of your HD, if it is USB 2.0 or 3.0, which used to program formats the same?
thanks ...
