Incorrect. They will look at the hard disk drive serial number. The serial number is stored on the disk drive and is impossible to change.
More importantly, to the person who originally stated the question:
You are getting way ahead of yourself. Enjoy playing on Live for right now and look at possibly modding your box. You shouldn't jump right in to trying to play with a modded box on Xbox Live.
Start with getting your box modded with an X3 and all stock hardware (HDD, DVD, Etc.) and familiarize yourself with the things you can do with a modded box. Then look at possibly upgrading your drive. Then, after you have messed around with loading games on your HDD and stuff. then you can think about trying to use live on a modded box.
Not meaning to sound trollish, but if you take it one step at a time, you will have much better results.
Just a tip, I have my old stock HDD with nothing whatsoever on it that I use for live, and I switch to my upgraded HDD when I want to play "backec up" games.
There are many many ways to accomplish what you want, and you will find one that suits you. Just take it slow, so you know what you are doing every step of the way. It will make it easier when you screw things up (trust me, I did)
