If you're actually using the same hard drive, and by "recovery" all you mean is that you ran chkdsk on it, then you're already seeing every file that the MFT lists, just by looking at Windows Explorer or getting a directory listing at the command prompt. Once chkdsk has cleaned up corruption, the MFT no longer "knows" about any of the clusters that chkdsk might have deleted or changed, it only knows about the current files and where they are on the disk. If you don't see a file listed in Explorer, then the MFT isn't going to help you.
If there were in fact files that were "lost", then recovery software MIGHT be able to locate them, as long as they were not overwritten since then. However there's a good chance they were overwritten since you've continued using the drive. I've never tried the GetDataBack software, but there are many different applications available for recovering files, most cost money though some may have a free trial. But every moment you keep using the computer, you're increasing the likelihood of making those files unrecoverable. Those programs work by scanning the drive sector by sector and trying to figure out what looks like a file and what looks like junk, but if your system writes over one of your lost files, then the software can't recover it.
How do you know that you lost 10% of your files?
