How can a device be unmounted, if the software can not identify it?

Without any usable system utilities to identify any device, and, no
file operations available, it is a bit like diving into shallow
rockpools from the top of a cliff, or, the famous test for voice
controlled operating systems, where the member of the audience yelled
out "Format C colon!".

Simply unplugging a mounted USB device, destroys it, from experiential memory.

And, it is not your data that is at risk.

Simply reacting like saying "oops", if hundreds of GB of data is
destroyed, does not help.
