OK just a heads up to all those wondering about using a old model HDD on the new slim by removing it from its case........its now been officially categorised a illegal modification and could result in your xbox being banned. This is from a post made by a member of the xbox support team on the offical xbox forums. offical xbox forums So this is just a heads up to anybody on xblive with this or who might be about to do it......i must admit i was playing with the idea of buying the cheap 4gig model and using it with my old official 60gig HDD, but seeing is it would result in banned console i now wont be bothering. Shame that.
