I cloned my XP HE/SP2 HD on 26 February this year and it has occurred to me to wonder what is the position regarding re-activation. I've just been browsing the MS site and read the following: One of the forms of piracy that Product Activation guards against is hard disk cloning. Not all forms of hard disk cloning are illegal. However, by comparing the hardware hash originally activated to the current hardware hash, hard disk cloning can be deterred by requiring re-activation if the hardware hashes are substantially different. So, what is the position when you clone an XP-containing disk? I haven't seen any comments on this forum and I couldn't find anything on the subject in the manual, so I'm assuming that it's not a problem. Is this correct?
