mount hard drive image that has ntfs format?

Forums: 

ok wanted to image my mom computer. Her computer is windows 7 and has ntfs. So... how do I mount it? Below is what I did.

used ddrecuse from apt-get install gddrecuse

custom@custom:~$ sudo ddrescue -v /dev/sda ~/mom/mom03142011.img ~/mom/logfile

NTFS signature is missing.
Failed to mount '/dev/loop1': Invalid argument
The device '/dev/loop1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
