File systems / partitions are normally managed by root and only root would be able to mount or un-mount.
However, if you want everyone on your machine to have the same privilege for a specific mount point, this is how you can do that.
Add “user” to the mount options for the desired mount point in your /etc/fstab file. In my case “/media/music”
I changed mine from
//192.168.1.200/Music /media/music rw,noauto 0 0
//192.168.1.200/Music /media/music cifs user,rw,noauto 0 0
