I did something like this a couple of months ago and seem to recall the 
NTFS partition being fussy about being deleted. I'm trying to remember 
what I did, I want to say that I simply used parted and hit delete 
partition as the only operation. After that completed, then I went back 
and restarted parted and put a new format.

Scenario 2 is that I dual booted into windows and used Partition Magic.

Scenario 3 is that Knoppix for some reason was able to do it, but Ubunut 
u wasn't for some odd reason.

Sorry I can't remember which one worked, I'll ask the person I did it 
for and see if she remembers.
