Card not detected after shutdown

Hi! I’m running the latest DietPi version, booting it from a 256gb ssd.

I had to shudown mi Pi 4, via DietPi dashboard, so in a proper way. After that i tried to boot it up again but i have the card not detected error. This is happening every time i shut it down.

Is there a way to solve? I always have to start with a fresh image

Please fill out the troubleshoot template and provide the exact error message.

And how is the drive connect? Does it have own PSU? Because RPi4 USB ports are not designed to power larger USB device.
