I can only mount my USB_driveZ (read_only).
I’ll try this without errors:
sudo mkdir /mnt/sdf1
sudo chown -R $USER:mate /mnt/sdf1
sudo chmod 755 /mnt/sdf1
sudo mount -o force,rw /dev/sdf1 /mnt/sdf1
Under drive permissions: user&group = root (not changed to user)
What can I do to solve my problem? I can only create folders/files with root on that USB_drive.
I want use gnome-disks to mount. Mount-options on gnome-disks with rw?
