I've never heard of that limitation.
It sounds more like the 137 GB BIOS
limitation. You may want to research
that to arrive at a definitive answer.
Hard drive manufacturers usually have
info on their websites about that sort
of thing. That is where I would start.

Why? With older hardware 2000 works better
(is more responsive).

Okay. Again, look into the possibility of
a 137 GB BIOS limitation. Up until just
recently I was using a 2001 vintage Shuttle
mainboard that had that limitation and no
manufacturer-provided BIOS update. The
last setup was a 320 GB drive and a 400 GB
drive. To get around the limitation I ran
one drive on a PCI IDE expansion card and
the other with an overlay (aka Dynamic Drive
Overlay). Neither solution required XP.
The rest of the system hardware was: a 900
MHz Athlon processor and 1 GB of 100 MHz
SDRAM. The mainboard, processor and memory
was given to me in 2003. In those days there
was a rash of mainboards that had defective
filter capacitors (
The bad capacitors caused frequent lockups.
I changed out all of the effected capacitors
and used the mainboard, processor and memory
for close to 5 years. Now I'm running a 2004
setup and the above setup is helping others
learn about computers at the non-profit school
I attend.

Probably. Upgrade means just that.
On the other hand, I forget. Just
having the 2000 disk may be enough.
Again, the drive limitation is not
a good reason to change to XP.

I forget. I believe that having the disk
is enough--but I may be wrong. If it were
me, I'd look to other solutions and not
look to the installation of XP to solve
your problem.
