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 . http://www.system-rescue-cd.org/Download/ http://www.system-rescue-cd.org/manual/Backup_data_from_an_unbootable_windows_computer/ Backup data from an unbootable windows computer http://www.system-rescue-cd.org/manual/Backup_and_transfer_your_data_using_rsync/ Backup and transfer your data using rsync Thank you very much .
