I have an Raspberry Pi 4 in Argon One M.2 case and I want to store my datas in an external drive.
I can navigate to ./media/ssd_samsung_evo_270/ but no further.
In the other messages, power supply is the first point raised.
But my case has a power supply of 18 W (5V - 3.5 A) and should therefore be sufficient.
Have you an idea ?
