Wiping with DD leftovers

Adrian-

 Merely a guess as I'm on the road without access to a test disk but I think
you're asking dd to write *within* the volume so you're still going to see
NTFS remnants. Are you trying to wipe the entire physical drive? If so, you
will probably need to access the drive at the physical device level:

   - C:\Users\adrian\Desktop\aft>dd if=/dev/zero
   of=\\?\Device\Harddisk1\Partition0 bs=1M --progress   *[check your dd
   --list for accurate device number]*
