manually partitioning non-boot disk (save data?)

Hello,

Hopefully someone here can help me, or if there is a more suitable
forum, please direct me there.

I reformatted a 2nd disk (\Device\HardDisk1) that had a Linux OS on
it. I was using GRUB on the 2nd Disk to choose between Linux and
Windows XP, which is on my 1st disk (\Device\HardDisk0).

After reformatting the Linux drive to NTFS and moving a lot of files
there, I realized I would need to get Windows to boot up on its own,
and after some luck, I got it to do that, but in the process I zeroed
out the whole MBR that was on the 2nd disk and the partition info
(where I had already reformatted to NTFS and saved a lot of files).

I have MBRTOOLS which allows me to edit the partition table and the
rest of the MBR for the 2nd disk, but I get an incorrect size for
that
disk after I boot into windows - it should be 80 Gig, but it's
showing
one partition at 7.88GB and then 66.65 unallocated.

Aside from the size problem with the partition, *I want to save the
data on the disk*, so if I get the partition entered correctly in
MBRTOOLS, will I be able to access it again? If
so, can someone clarify the partition settings for me.

I have the following set up (obviously incorrectly).
act = 00 (I think this means non-bootable)
type = 7 (for NTFS ?)
start CHS = 0,1,1
end CHS = 1023, 254,63 (note, when I enter 63 for Sector, the
Cylinder
auto decrements to 1022)??
LBA start = 63
LBA Length = auto populated at something like 16,5??,??? (sorry,
forget the exact)

This is Seagate's 80GB Hard drive, model ST380013A. Maybe the auto-
decrementing of the Cylinder value is to blame and I need to use a
tool other than MBR TOOLS

Thanks in advance,
Brian
