Question to avoid a "registration doesn't match"

[mindonstrike]

I read somewhere several days ago Admin said changing a HD could cause Hoster to think it's on a different computer.
My question is does that apply to any internal HD drive or just the one that Windows/Hoster is installed on?

I've got two drives, one for Windows and programs and another strictly for KMA's

I'm almost to the point where I need to install a larger drive for my KMA's on my show PC. I've got a backup PC to use in a pinch but I would prefer to avoid that pinch!
