If the data is that important to you, and the hard drive is physically "healthy", you can do as many scans as you want with different apps/settings. Don't commit to the writing of corrections until you get the scan that most accurately represents what you thought was on the disk to begin with.
As previously mentioned a screenshot would be great for all to look at.
That "c: 8mb used out of 100gb" does not look good.
You might consider file recovery to other media before committing a correcting write to the disk.
EDIT: Nevermind on that "c: 8mb used out of 100gb" comment. Your post a minute ago reminded me of that format. Certainly commits it to memory a little better as you mentioned it again.
