well a locked drive is just a stupid thing thst ms does. some of teh new drives that they make cant even be locked any more. its like a very outdated security method. the drive will still function teh dsme, wheter it is lcoked or unlocked. if you want to go live, just get a copy of configmagic (from the usual places), and lock your drive. then run a backup in evox, and copy all of the files that it makes to your computer.
that way, if your xbox decided to shit itself, you can recover the hard drive (coz its locked, itll only work on the xbox)
