Wiping with DD leftovers

I'm sure all of you know that just zeroing it the whatever, isn't  
really "wiping". With the appropriate tools you can still recover the  
data.

Might want to look at a DoD 7-pass erase... Or even: http://en.wikipedia.org/wiki/Gutmann_method

Just making sure ;)

Ive noticed something. If I use the Windows DD from http://www.chrysocome.net/dd 
 and use this command:

C:\Users\adrian\Desktop\aft>dd if=/dev/zero of=\\. 
\Volume{de891b6a-8432-11de-86d4-005056c00008} bs=1M --progress

it seems to leave some data on the beginning (sometime) and end  
(always) if the drive had  been formatted NTFS before.

I'm using WinHEX to verify by the way. Any ideas?
