Ejecting memory stick

Is there a way to “eject” the memory stick from the control box with the power still on? If I just remove the memory stick from the control box with the power on, when I plug the stick into my pc it detects/thinks there’s a problem with the stick and runs a diagnostic. If I shutdown the control box; then remove the memory stick, when plugged into pc it doesn’t detect any problem.

there isn’t. just ignore the windows ‘problem with disk’.
