Probably a good time to mention systemd automount. This will auto mount and unmount drives as needed. You save on your energy bill but the trade off is that first read takes longer as drives need to mount.

You need 2 files, the mount file and the automount file. Keep this or something similar as a skeleton file somewhere and copy over as needed
