So I’m trying to figure out how to put the title update on the my Xbox 360 320 HDD external hard drive keep in mind this is the original Xbox 360. I was successfully able to put it on the usb xbox 360 formatted hard drive, but I want to transfer it to the actual Xbox 360 drive, but I find out you can’t copy or move title updates through the xbox 360 menu. The only thing I have to connect my xbox 360 hard drive to the Pc is the transferable cable. The weird thing is that I can load my 20 gb old Xbox 360 hard drive through Horizon, but not my 320gb I get an error.
