Can't find mount source

Hi,

When I try to mount one of my drives I'll get this error:

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount -v --source '/dev/sdf1' 2>&1' with exit code '1': mount: can't find mount source /dev/sdf1 in /etc/fstab

For some reason it tries to mount wrong. How do I solve this?

To quickly resolve the issue I did a reinstall.

I really like to know if there is way to solve the above issue without a re-installation. If so please let me know!
