I mounted an exfat usb drive with the Drivemanager.
As root or dietpi I have write permission to it, but not as a user. I tried chmod 777 -R /mnt/128GB, did not work.
ls -lah gives drwxrwxr-x root: dietpi for /mnt/128GB.
I also unmounted, unplugged, rebooted, replugged and remounted the device.
Samba write is possible as dietpi, but not as user.
Nextcloud write access to this mounted device is not allowed.
In device manager read only is disabled.
I don’t know what’s wrong.
