I was searchiong on google and found this,all you have to do is unlock your hd, hook it up to your pc, and it might work,someone check it out, i will try it also.
just go to the ninaries folder, and open the .exe.
heres the link

good luck
if correct this should unban an actual hd serial, or even swap an hd serial so if you use a stock dirive for live, you can swap your large hds serial with your stock...maybe
we'll see
