Upgrading XP computer. Will it need re-activation?

["<p>sychotic <c>hicken" <"\"Bill Jillians\""@mysteryisp.com>]

I have a question about the XP operating system and adding new hardware 
to my system.  Is this the right newsgroup for this question and if not 
can somebody point me to a more appropriate one? Perhaps something in 
the overblown Microsoft hierarchy?

Specifically ... if I want to add more space to my computer in the form 
of adding a new hard disk which I would have to do by taking out a zip 
drive or a DVD drive, would XP pick up that a major change had been made 
and require me to activate again.  I don't have the XP installation disk 
for this computer so I'm not going to upgrade until I can be sure it 
won't then make this computer unusable.

Thank you
