the easiest way to set up a new hdd if you are modding your box is to install your modchip first, then put the hdd in and boot to either firefuc%ers or slayer's install disk from dvd and it pretty much sets the hdd up by itself. i don't think there's much point in installing a bigger hdd in a non-modded xbox, without a different bios you can't backup games, etc(unless you can do it with a exploit, but that's not really a noob thing anyways) finally, for those of you who want to just run unsigned code (backups, homebrew apps, games) and don't need all the features, cheapmods like the NEWER alladins (such as the XT) have worked good for me there's also a new chip called the clevermod, based on a alladin, either of these are reliable and you save 30-50 bucks by giving up a couple features (most cheapmods are $15 or less)
hope this helps you guys
