Hard Disk Monitoring

While chkdsk does help sometimes, it is only focused on the health of NTFS and not the files. It is not unusual for chkdisk to discard files or parts of files for the sake of NTFS integrity. I am looking for a tool that places file recovery over repairing the NTFS but still repair NTFS.

I have searched the website but have not found the terms of program updates.
If I purchase Hard Disk Sentinel Professional, what updates are included in my license?
What updates must be paid for?
