XBOX 360 slim question

[<LT>YosemiteSam[NL]]

I recently finished Tony Hawk HD and after that I wanted to play the older XBOX versions I have on the 360 slim.
Ofcourse I need a harddisk (I had one for my old 360 system which broke down) in order to play the games.
I tried using the old harddisk but to no avail (I looked up how to do this on youtube).
Is there a way to let your 360 "think" there is a harddisk in the system ? I don't want to spent 80 euro on a new harddisk and I don't want to hack a harddisk (seems to be too much a hasle for only 2 games)

Thx in advance

Well, answering my own question I think;

Found this;

Reason being, the Xbox Originals require a special emulator which is downloaded as part of an update. This update is only able to be placed on a partition setup on Xbox licensed HDD's.
