A better strategy (which will get rid of that warning later on, etc.)
is to use Parted to copy... it can resize as it copies ;)

        # dd if=/dev/zero of=/mnt/imagefile.raw bs=1M count=310
        # parted /mnt/imagefile.raw
        (parted) mklabel loop
        (parted) mkpart primary fat 0 309.9
        (parted) cp /dev/hda 1 1

This is mentioned in the Parted manual, in section 8.

That is by design, yes ;)

The only problem I can think of, is if defrag decides not to move some
