Recover a USB drive with hidden partitions in Windows 10

gistfile1.txt

I managed to do it with diskpart. What I was missing is the command to create a new partition. So here is a run-down of all the commands I used, step by step.

Beware that when typing select disk 1 (step 4), your disk number may be different. Selecting the incorrect disk might erase your whole computer's main disk drive, losing all your data on it.

I assume you know how to get to the Run prompt since you have arrived at SU. But if not, just press and hold down the Windows key on your keyboard. While still holding the Windows key, press the R key. Voilà! La Run prompt! L'invite de commande!

    cmd
    diskpart
    list disk
    select disk 1 (Careful! Choose the correct number here. See note above.)
    list partition (Inspect the results to double-check this is the right disk)
    clean
    list partition (There should be none)
    create partition primary
    list partition (There should be one)
    format fs=fat32 quick
    list partition (There should still be one)
    exit
