Problem description: After
formatting, the disk only has a little hidden files generated by formatting. After the disk is formatted, how to retrieve the files is very simple. 
Tools/Software: Extreme Data Recovery Software
Step 1: After the program runs, directly select the partition that needs to be recovered, and then click the "Start Recovery" button in the upper right corner to start scanning data. 
Step 2: After the program scans the file, it will be placed in the directory with the same name as the disk to be restored. 
Step 3: Tick the data to be restored, then click the save in the upper right corner, and the "Save As" button will copy the checked file come out. 
Step 4: The last step is to wait for the program to copy the files to completion. 
Note 1: If you want to restore the format of the hard drive, you need to pay attention, you must restore the data before saving files to this disk.
Note 2: The data recovered from formatting needs to be temporarily saved to other disks.
