I got a 120gb drive with Shivering Isles DLC. I didn't pay for it - it was on the hard drive already and was NOT connected to my gamertag. I booted up the 360 and was able to access the DLC with my gamertag and even did some saves.

You could just try it and see. OR - go under account management and see what was downloaded and redownload it.

Someone probably load that DLC via disc.

^ Yeah, you can't really copy dlc. You can transfer it with a transfer cable but then the dlc will be deleted on the original Xbox 360 where you transferred it from.

You can plug the transfer cable into a pc and copy the data to a different HDD, but the DLC is still tied to the console/GT.

From my experience, it tie to your gamertag AND console ID. I just recently have MS did license trasfer for me and it only transfer stuff that I bought to my new (refurb) console. My son stuff stay on his console even stuff that I bought on his console with my GT it stay on his console.

Also did you reg. the new console with his gamertag then his stuff should go to his new console.
