well i checked the manufacturer date and it says march 15 of 07 on back of the xbox 360 elite. i have gotten all the way to the step in taking part the xbox where i need to a torx 10 screw driver but my dad has them in his truck and doesnt wanna get them out till tomorrow so looks like im going to have to wait to see what kind of drive it is definitely. hooefully it is a drive i can flash. is there any way i can help in the development of a firmware flash for the new hitachi drives if mine turns out to be that one? or are there sample firmwares that can be tested, or what stage are people in of developing a working firmware for the new hitachi drives? sorry for so many questions but i am new to the xbox 360 modding scene. i have a regular xbox modded with an xecuter 3 chip with a 500 gig hard drive. hopefully i can be some help to this community.
