Asking for a friend again, recently he purchased a 320GB Xbox 360 HDD, it was obviously purchased used as the profiles currently on it do not contain any characters, only generic faded characters. I told my friend the hdd may require a system update and then he asked if only hdd needs an update or if the console (without hdd) requires updating as well. Originally the console has 4GB internal memory but hasn't been connected to internet or Xbox Live in years so it did not update automatically.
