Hello, my plan was to use a Raspberry pi with a 2 TB HDD connected via USB as Cloud storage. I installed it and I can reach the gui. However if I try to configure a folder on the external HDD it tells me that I don't have permissions to write. I attached a screenshot. Could somebody please tell me why i don't have permission to write on the drive and how I can change it? Yes, I am a noob when it comes to Linux Thank you in advance.
