Can content stored in XBOX 360 hard drive be accessed by any account?

I'm about to sell my 360 and I have some games and a lot of DLC stored in the HDD. If I remove my account from the console but keep the games/DLC will the buyer still be able to access that content?

DLC Content has 2 licenses. One is to your account, the other is to the console it was purchased on. If you remove your Profile, and you purchased the games on that console they will have use of the games. If not then they will not have use of the game. Also the games are only usable until the original gamertag transfers the License to a new console. Or they format the drive or become corrupt.

That's not true nothing is account bonded it is bonded to the XBox 360's internal memory so what ever you had previously downloaded to that console can be accessed at any point and time by any profile however if you were to download it again to another console your profile would always have to be singed into XBox live for you or anyone else to use the DLC or previously downloaded games.
