Struggling a little to understand how USB's interact with the Pi, well linux in general I guess.
Basically if I insert a usb stick a box pops up asking to open the file manager so I can access stuff that way. How do I unmount this drive though, I have tried looking for sda1, but it's not found. Does this mean that I have been accessing the usb without mounting it, or is it called something else.
Basically I want to remove it from the RPi without having to shut it down every time.
Please help, I can't find any help about already mounted drives
