Recuva Ignores 31,000 files?

Is there any way to recover these files, I did a deep scan on an external hard drive that was accidentally formatted (which deleted everything) and I was trying to recover all the files. 6 files were found and 31,681 files were ignored. I also did check the first three boxes in the action/options in the options. Please help, the files were very important and impossible to re-get! Thanks!

You need to check the fifth box as well.
