No, there is a post somewhere explaining the difference between an XBox and a GamerTag

basically you have problems when you connect to xbox live for the first time, not when you register a gametag
The Halo 2/Nov 9th XBL Bannings - AKA Marriage TheoryFrom what I can tell, you only get banned if you swap your HD *after* you first go onto XBL with a given Xbox.
If you're planning to upgrade an Xbox's HD, you need to do it before you first connect it to XBL.
But if you didn't do your upgrade before you signed on to XBL with that Xbox the first time, then you should sell your Xbox, and remod another one.
And finally, remember to use an XBL blocking BIOS so you don't get banned for having an active modchip!
