Have you write anything new on this cleaned disk?
You could try
a disk recovery freeware to get back your files as long as you have not put anything new on this drive to rewrite the original data. The rewritten data can be gone forever.
As to this freeware, it is really free and efficient since it has helped me recover all of my photos, videos, music and files after accidental format. It can help you, too. Go try it!
Tips for you:
1. Do not store any new data on this drive avoid the original data overwritten by new data.
2. Do not save the recovered data on the same drive in case of recovery failure.
3. Do not forget to back up your important data before you do any change to it in the future.
