Hello,
have you tried
I made a post on the blog here - http://yeyelinux.blogspot.co.uk/2017/05/...g-and.html
of how to mount manually, unmount, list device, and create FAt32 file system using terminal.
I had tried to use a installer for OSMC distro, and it had compatibility issues, it made the sd cards unmountable, unformatable, etc.
I couldn't do anything with them in Gparted or Disks, I also tried on Windows using the SD card official software.
Mostly the info I was given was the cards were trashed, unfixable.
I solved it using the method on the post above, (at end of post) in terminal on LL and they were usable again.
I then tried the commands on other device including USB flash drives and external portable drive, and it worked.
I didn't find this odd way/sequence of the commands anywhere online, and only the exact sequence worked on the corrupted ones, as I corrupted them again and tried all different possible orders for the commands.
Example it says not mounted you may try to work on it and it says it is mounted, because if it was not mounted then it would not be giving you any information about the drive, so it telling you the error it is not mounted/unable to mount it is not fully accurate.
So to format and create filesystem fresh/clean you will need to unmount it in terminal etc.
As you want to format it, it would be useful to play with the sequence on the post, you may also discover a different sequence of the same commands that fixes this error, that will help others in future.
Edit - similar to your drive, the sd cards once inserted when corrupt also could not be unmounted, as they were not even displaying in Home tree/menu.
By the sd cards working afterwards I mean I was able to install a full distro and use it many times on it without any issues.
have you tried
Code:
sudo mount /dev/sdb/mnt
