Just a few questions I could not sift to the answers of in the endless information garbage heaps.

Will not unlocking my orginal M$ 8 gig drive, cause any adverse effects with my EEPROM data if I simply piece the XBox back together with a new 40 gig IBM drive?
(Providing of course I use an auto-installer type NEW HD Format program)

If I am using an old 40 gig drive that is formated in NTFS (from my win2k box), can I leave it in an "as is" state and throw it into the XBox? Or do I need to wipe the drive first?
