Let us explore your drive again with Test Disk. May be a repetition but you are doing it now under my control.
Run TestDisk again, and follow these steps: Be sure you have only the faulty external drive is connected.
A. At the first window, select “No Log” and press the <Enter> key.
B. Select which disk to analyse, choose “Proceed” and <Enter>. ( Choose Disk not drive)
C. Select partition type – Intel if it’s a PC then <Enter>.
D. Choose Advanced > press <Enter>.
E. Choose Boot > press <Enter>.
Post the resultant screen. Remember I only want that Window not the full screen in the background. I shall see it only tomorrow morning that is about 10 hours from now. Post the screenshot and then quit TestDisk. We shall continue after I see the screenshot.
Here are the screenshots:



FYI, when I've written the TestDisk result as I said before, I've also rebuild bootsector from the backup one (Rebuild BS).
