As noted, this is greatly excessive. Do:
dd if=/dev/zero of=/dev/hda bs=512 count=1

That's a bs bs, if you follow me. If you're going to use bs (byte-size)
and count, use a sane value of bs like the the logical block size.
Otherwise, just leave it out; there's no need.

As noted, you'll need to fix the MBR of hda with fixmbr (or use GRUB).

There is no need to defrag, since you've already done ntfsresize and are
simply going to do a bit-for-bit copy from hdb1 to hda1. It might have
helped to do a defrag /before/ ntfsresize (since you were "squeezing"
the NTFS filesystem), but no point now.

Possibly, due to the earlier ntfsresize.

Mostly.
