What I would do in your case is to make an image of the disk with `testdisk` and after to work on the image (it will help if the disk have some physical errors or write troubles or data communication error )

`testdisk`and its documentation can be found here: https://www.cgsecurity.org/wiki/TestDisk

If you need a file level recover of the disk, you can use `photorec` from the same author

Not that except if I have no choice, I would never work directly on the physical media I'm trying to recover, the idea is to always make an image (device block copy) of the disk and to work on a second copy of the extracted image (always keep an original copy of the extracted image of the disk and copy it each time you want to try something new to recover)
