unfortunately, you are stuck with just reformatting the drive.   you won’t be able to retrieve your data, even through data recovery. 

this was something I had to learn the hard way, myself.  and it’s why I keep all my data on multiple drives.  as a matter of fact, every chance I get to buy a drive for cheap I grab one, this way I can just throw data on it.  I’ve never lost anything since.
