Thunar does not see that partition at all
Root Thunar can see the partition and the Data file and can open it and see all the data files in there.
Dolphin can see the partition and the data file but cannot open it. I can force Dolphin to open the file but then it won't open Documents, Downloads or any of the other files inside Data.
The owner of the Data file is me so I should be able to open it. What am I not seeing and why can't Thunar see the partition?# /etc/fstab: static file system information.
