|README. The WD1600JB hard drive works perfect in my xbox. I just put it in yesterday. It is a little bit noisier than the stock one, but well worth it for the price (59.99 at best buy.) Notice: WD1600JB/WD1600JBRT/WD1600JBRTL are all the same EIDE hard drive. I believe all of WD's EIDE hard drives are lockable.
