You may try

SystemRescueCd is a Linux *system rescue disk* available as a bootable
CD-ROM or USB stick
<http://www.system-rescue-cd.org/Installing-SystemRescueCd-on-a-USB-stick/>;
for administrating or repairing your system and data after a crash.


This is a Live Cd , without installing it , you can mount supported file
system ( there are many including ntfs ) and copy files , etc. from that
file system .
I think , the most useful tool is this Live CD . It can be used in Linux
and Windows computers .

My suggestion is to learn how to use it before attempting any repair on the
damaged disk . First try to copy files into another disk .
