    Ah, that got it.  Now that I've stepped back and looked at your comments, it
    makes perfect sense.  Thanks to all for the assist.

    All well and fine, but you've just created an image of the entire hard
    drive, my friend, which is why mount is complaining, as there clearly
    isn't a valid superblock, but instead a master boot record. :)
    
    You should check out the partition table using "fdisk -l /dev/hdc",
    then "dd if=/dev/hdc1 ..." if the NTFS partition is the first and/or
    the only one on that disk, or use the corresponding partition number.

    Just a note: the following is also possible and saves you one step:
    
        $ mount -t ntfs -o loop ./testing.bin /mnt/windows
    
    Cheers & good luck,
