I believe the calibration for these grinders looks something like
Unplug power
Slowly turn grinder by hand while empty
Slowly adjusting grinder knob until grinding plates just barely touch when spun by hand
Adjust dial facade to indicate this is the new “zero” location
Either way, the term “calibration” + the name of your grinder should get you a fairly specific run down.
It’s worth noting that if your grinder wasn’t calibrated like this when you got it then your notes will indeed need to be redone. But only once because next time you disassemble for cleaning you start at the known zero point again by going through the simple calibration process.
It’s worth noting that the job of auto-mounting a removable drive is often hidden behind the popular file managers, if you want to do it without one you are probably looking for the “udiskie” application that does this in a more agonistic/generic sense. https://github.com/coldfix/udiskie. With that running in the background to automount, then you can just access the drives from their auto mountpoints in the default location of /run/media/username/drive_label
