Thanks for your help Pegasus. You were right about something being different
between versions. First, let me say that the HD I was trying to install
windows on was a 1 TB WD HD. I finally realized that the original version I
installed on this HD was the Home Upgrade, which I had slipstreamed SP2 on
it, while the PRO full version was from the pristine disk with no SP2. As I
recalled SP2 greatly extended the partition and HD sizes. Apparently without
SP2, the installation was not the same and the HD with the the large
partitions was incorrectly recognized.

After slipstreaming SP2 into the PRO version, the problem was resolved. Feel
kind of dumb as I should have remembered the difference and its effect on
large HD's without SP2. Thanks again.
