If you are happy to lose all data on drive 3, this is what to do.

Open admin command prompt and type following

diskpart

list disk

select disk 2 (windows starts at drive 0 so drive 2 is drive 3 from minitool)

clean

create partition primary

select partition 1

format fs=ntfs quick

assign

exit

exit

If you want to backup OS drive, use an image backup to that drive, not cloning.
