I accidentally started to format my hard disk of 1TB, that was formatted as ntfs, with FAT32 format. When I saw what I did I stopped formation and get the HDD out of computer. Now when I get in Gparted it show me that there are files on HDD but when I go to file manager to access them I get some strange thing (2nd picture).. I tried testdisk and searched for partitions (quick and deep) and the only thing testdisk found was that one broken partition.
Now, I know about photorec but I still have hope that testdisk will help me.
This is how gparted see my HDD:

And this is problem that I get in file manager:
What should I do?
Thank you!
