I have seen many people posting about their Xbox 360 slims with huge amounts of Gigabytes, sometimes getting to 6 or 8 Terabytes !! I understand that RGH/JTAG systems can use drives above 500GB and it is also obvious that you cannot squeeze more than one HDD into your slim. So, how do they get to do it?? and if that is possible at all, can these systems be used normally online as official? I have Demon installed and was looking at my possibilities for upgrading my 250GB drive. Thank you for any suggestions.
