I am going to replace the Hitachi DVD drive in my son's XBOX 360. Everything I have seen about replacing it says that you need to flash the drive or it won't work. But then everything I have seen about flashing the drive says the purpose of flashing is to allow playing burned disks. But what I'm wondering is if we don't play burned disks, do I still need to flash it? Thanks in advance for any help you can offer.
