Undeleting lost files even after emptying Recycle Bin is actually quite a possibility, if you have Disk Drill, of course. It offers unique algorithms for deleted files restoration no matter what type of file system you are using or what type of files you want to get back.
As soon as you realize you deleted a file or a whole partition the best thing to do is disconnect the storage and boot from another drive rather than the one with erased data. Try not to use the drive with deleted data until you are ready to perform the deleted files recovery.
