write ntfs partition with dd

[Fromm Andreas <Andreas.Fromm@arbeitsamt.de>]

Hi,

I need a simple and fast way to restore the computers of a teaching room running WinNT after they are modyfied during the different trainings we offer here. I was thinking of making this with a linux boot cd wich gets the image from a server and writes the partition. Now my question is, is it possible to write a ntfs partition from an image with dd?

I meen something like this:

#create the image
dd bs=512 </dev/hda1 of=/netmount/image

#play around with the machiene

#restore
reformat ntfs partition
dd bs=512 if=/netmount/image >/dev/hda1


Greetings

Andreas
