External USB/hard drive

So, I just got an xbox360 without a hard drive, and my parents got me a 1TB hard drive called " My passport ultra" and after we formatted it and everything, my console is still not allowing me to play Xbox original games. what did we do wrong?

Solution 1:

On the Xbox 360, you cannot connect external storage and use it as an official Xbox Hard drive.

Source(s):

You can play some original Xbox games on your Xbox 360 console if you have an official Xbox 360 Hard Drive.

Also, "supported content" on the Xbox 360 page shows that you can only run Xbox games from an official Xbox 360 Hard drive.
