Because you want to make changes on a storage device, you are asked
to enter your password. You can add your user to the group: disk to
avoid this.


who or whoami - my login-name


id - more details


groups - all your groups


less /etc/group | grep disk - focus on disk


Add an existing user to another group, like this:


sudo usermod -aG disk LOGIN-NAME

I saw my entry not immediately check it with:
cat /etc/group
