Not anymore, there has been a project going on for quite some time. So far, a G partion was made available, and people are installing drives as big as 300gb in their xbox's (not sure if it shows it all though.)

Im not sure how to help you though, i started reading that post but it is full of crap and pointless replies more than ones that can actally help (almost everyone is asking the same question, and no one is answering them).
infidelity, im just curious. Did you get the xbox's to boot normal with the modchips off?
