Sorry I need to reword that, its not realy that ntpasswd didnt work, or that it wasnt able to reset the password, its more a mistake on my part, I assumed because the drive was NTFS and I was unable to access folders, that this was because I needed a password. When I used ntpasswd, it remarked that Administrator problably had no password. But in the end Partition magic alowed me to access the folders and as ive now learned, its because of SID missmatch not passwords.

I did try ntpasswd afterwards on my own drive and was able to erace one of my acount passwords. Sorry for any confusions.
