Hardware changes & XP pro/office xp install nag..

Originally, I had 2 60 gig drives setup, both patritioned
as 30's, o/s (xp pro) installed on one partition, and
other set up as logical drive. the other drive was set up
as a image, and hidden (both partitions). If I go any
further than setting
up the hidden drive as 60 gig, (restoring from a image
file) and making it active,hiding the other 30 gig
partition on the other drive with the o/s, xp tells me
it needs to reactivat, no problems there..BUT I get
errors from ALL of the office xp products telling me I
need to reactivate them, put the install disk in....

When I put the install disk in nothing happens, the
errors go away, but the next time I go back in the same
program, it happens again. If I try to run the setup off
the office xp disks, it tells me that the patch is
invalid. I have previously downloaded and installed SP 2
for all the products, and it worked fine, except telling
me that the installer may be corrupt. other than the fact
that it totally disabled publisher (which I don't use
much) it was ok.

Now for the question:

I would like to make some hardware changes to get more
room on my drives, (put 2-4 120 gig drives on the raid
controller)(highpoint 372) and get around this problem.
other than uninstalling all the office products, and
reinstalling them, downloading 2 service packs (HUGE) for
each of them, is there another way around this?

(if I enable the raid controller with no drives attached
to it, office xp has the above problems...currently
running on a 60 gig drive set up as "c", and it works ok
now)

note: I'm not changing the motherboard, memory, or
bios,not exceeding 137 gig size limit on bios on MB, for
raid controllers, just using what I had originially to
better suit my needs.

motherboard is abit kr7a raid board, that has 2 primary
ide controllers, (one set 60 gig drive set up as master,
60 gig drive (2 30 gig partitions, 1 hidden) set up as
slave, on the other controller cd-rw set to master, dvd
set to slave, and 2 ide connectors for raid, (currently
unused) the controllers for raid can be used for a
standard hard drive, without setting up the raid
functions.

at what point does XP pro, or office xp think that you
are installing on a new or diffrent machine? if it is
just a reactivation, that is fine as long as it works, I
would like to increase my hard drive space for "C" drive,
clone it to a spare drive, hide it, and use the 2 60 gig
drives for data storage. (using raid in a mirrored array
takes my performance away drasticially due to disk
writes, and leads to unstable write behind errors while
moving large amounts of files. (same goes for a external
drive--errors)

I have partition magic 8 & drive image 2002, so my life
is somewhat easier at accomplishing this task..
