Having issues with your DietPi installation or found a bug? Post it here.
I guess @MichaIng could explain it better than I but the RPi4 is limited on the amount of power it can provide via USB. We had a couple of repots in the past on issues caused by this. Usually we recommend to use external power supply for external disks
Pls let us know if a solution is working. This could help others if they hit by similar situation. Your DietPi Team
