It will if you create a new partition table that reflects the new
disk size, and do not copy the mbr from the larger disk. You will
need to re-install the Windows boot loader to the mbr of the new
drive, or install the Grub boot loader there, and use it to select
Windows or Linux.

Ok, I think I understand:

/dev/hda - spare 80GB drive
/dev/hdb - old 150GB xp drive (primary partition ntfsresized to 20GB)

dd if=/dev/zero of=/dev/hda

This will write zero's to the entire drive - a bit excessive, and
time consuming. Add count=1 to the command.

fdisk /dev/hda
- create new primary partition(hda1), bootable, type 7 (NTFS)
- this then creates the windows MBR?

It does not put the Windows boot loader one the drive, but it does
create a new MBR.

dd if=/dev/hdb1 of=/dev/hda1 bs=10000000 count=2000
 - copies resized xp partition to new drive

If the partitions are the same size, you should be able to do:

dd if=/dev/sdb1 of=/dev/sda1

But I still like using parted instead of dd for this. It will handle
any differences between the partitions.

Reboot to new drive and all is well.  Defragging is factored in
somewhere prior to this operation.  I think upon reboot this will
trigger xp to perform a chkdisk.
Does this make sense?

I would defrag before shrinking the partition, but I guess you have
already shrunk it. You are also going to have to boot from the
windows CD, start the recovery console, and run fixmbr. (Or you can
do your Linux install, install Grub, and let it boot Windows/Linux.)

Ok, great.  Thanks everybody for the information.
