I am trying to create an image of a laptop that has windows xp and upload to an imaging server using the img command. I am using a zen 7 cd every time i type this command i get returned to the bash prompt saying there is a segmentation fault. i even get this when trying to download an image. i assumed it might be ntfs cluster size needs changing (default being 4k then set to 8k) but that didnt make a difference.

What else could segmentation fault mean

any help would be much appreciated
