Linux, dd, and image file

I have been trying to mount an NTFS image file based on a procedure I had for mounting floppy disk images and viewing them read only.

Basically, I md5 the original drive, make a working directory on my Linux drive, and then 'dd if=/dev/hdc of=testing.bin conv=notrunc,noerror,sync". I then make a /mnt/windows directory to be used as the mount point and chmod 777 this directory.

The binary file is created fine, and the md5 hash of the file is the same as the original drive. But here is where I get stuck.

I do the following:

# losetup /dev/loop0 testing.bin
# mount -r -t ntfs /dev/loop0 /mnt/windows

It keeps telling me:

mount: wrong fs type, bad option, bad superblock on /dev/loop0,

       or too many mounted file systems

I am sure there are not too many mounted file systems, and I am sure the original drive from which the dd came was NTFS. I have ntfs compiled in the kernel. I'm using Red Hat 8.0 for this.

Anyone have any ideas, or is what I am attempting even possible?
