Alright, I have two 360's, one is my legit one for playing on live, and my other one is my jtag, which I will never connect to the internet. So far the games I play off of my external hard drive with the jtag I have been using a flash drive for a profile to save with. My question is, can I plug my xbox 360 hard drive with my legit xbox live account into the jtag? Will playing games off of the external hard drive and saving the progress on the microsoft one cause my account to get banned, or do something to my hard drive? I will not connect to xbox live obviously, but I was wondering if it is safe to plug in my microsoft hard drive with all the legit files, dlc, saves, etc and not have anything banned or screwed up.
