 I wasn't sorry for posting the link, rather for not posting in the previous
post I made with that reference.

Do a search on Google groups for them many seeking how to remedy this kind
of situation, it doesn't refelct the % you give !

And this is what the OP ask, as he has (and stated) a 200gig hard drive?

Yes, the OP stated SP1 was installed, and most MOBOs over the past 3 years
will handle drives this large.

In his case it is, as Windows still reads disk size and usage in data form,
and the BIOS has no control over Windows, and as Windows has no control over
the BIOS. He clearly stated that the BIOS is set to recognize, and it does,
his 200gig drive, now it is a Windows issue with SP1 installed that the
correct size is not seen, he needs to make changes to the registry. Maybe
SP2 will automatically do this from now on, with the 48bit LBA issue on
drives larger than 137gigs. Again, if you do a search, you'll see this is a
comon issue, and not the over 99% you think this doesn't apply.

Read the OP, and you'll see that he stated that it is set in his BIOS and
seen there.

Yes, they do, and almost all really good brands going back 2 years.

Tom:
I think I have deciphered your response accurately as I respond to your
remarks, but in the event that I haven't, please forgive me.

It every case that I've come across, both personally and based on
information gleaned from those I perceive to be accurate sources, when a
user reported that his or her XP system did not recognize their
large-capacity disks even though they had a motherboard whose BIOS supported
such disks and had installed SP1, it turned out that this simply wasn't the
case. In some instances the BIOS did NOT support large-capacity disks,
contrary to what the user thought. In other cases incorrect jumper settings
on the hard disk negated its ability to be recognized at its full capacity.
In still other cases the user had unknowingly changed a relevant BIOS
setting on the motherboard limiting its ability to recognize large-capacity
disks. In still other cases SP1 had either not been installed (again,
contrary to what the user had reported) or had been a faulty installation.

In no case that I've ever come across or am aware of where the motherboard's
BIOS truly supported large-capacity disks and SP1 was properly installed was
there ever any need for registry modification as outlined in that KB article
303013 except in that tiny fragment of situations that the article details.
