External disk unmount itself

I have and external 8 GB Lacie disc that unmount itself during the day. It is connected to the back of my Mac and has an external power cord that is connected directly into the wall

I am at a loss

FWIW, some drive brands seem to do that. I assume it has something to do with the firmware. I had a lot of eject problems with WD drives in High Sierra, not as much in Mojave, so far none in Catalina. Same drives.
