Ok.. I have a 4GB Xbox (with the built in hard drive). Back when I got it I was asked if I wanted it swapped for the 250GB but I said no (Because I knew nothing about the sizes). So I was stuck with this one. My previous Xbox got the three red rings and was the 20GB or something. I have an Xbox hard drive transfer cable and my old hard drive. Now, I want to download Street Fighter IV of the marketplace but it is 4.61GB. Can I download the game to my old hard drive and then play it through the transfer cable? I am quite frustrated. Thanks for any answers.
