So I just recently found out that in order to play online games like halo and BO2 you have to have a hard drive. I'm not a console gamer so my son informed me of this when he was complaining that he can't play online. So I fig'd ok, can't be that hard. Did some googling and found that you can potentially use a laptop drive or you can go with Microsoft's "Certified" hds which is priced ridiculously. I have a spare WD 250gb hd, which according to this post: http://www.overclock.net/t/1204909/can-i-use-3rd-party-2-5-hard-drive-with-xbox-360 meets 1 of the model #s suggested that will work on the xbox. (I have the WD2500BEVS model) I've found some links on how to do it, but these seem kinda dated. If I swap out the drives using the hd hackr method, will this ban my son from xbox live? Is this pretty easy to do? Are there more up to date instructions on how to swap the hd? Should I just fork out the cash for a "certified" hd?
