Yes the new one, you need the eeprom.bin from that xbox
after i unlock it, can i keep it unlocked? whats the point of locking it in the first place?
Yes the HD will say unlocked once you locked it and you will need to lock it again with the new xboxs eeprom.bin to even be able to use that HD on that xbox
The reason the HD gets locked is only so the xbox can open it when it boots up, when it boots up the HD unlocks it self reads the files it needs to load up the dash that you see every time
