When I mount a USB pen using Thunar, I cannot write to it but I can read from it. Xubuntu 16.04.
I can write to it as root, from the command line.
mount lists the device thus;
/dev/sdb1 on /media/morpheus/FILM type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
My /media directory looks like this;
[ morpheus ]-[ /media/morpheus ]
--> ll
total 16
drwxrwxrwx+ 4 root root 4096 Jan 15 11:58 .
drwxr-xr-x 3 root root 4096 Apr 26 2016 ../
drwxr-xr-x 20 morpheus morpheus 4096 Jan 15 11:30 Data/
drwxr-xr-x 3 morpheus morpheus 4096 Jan 1 1970 FILM/
EDIT : The problem exists with ext4 formatted pens, but everything works correctly with NTFS formatted pens.
Note: I can write to the pen, as root, from the command line so I am able to continue with my work. I am looking for a solution to making Thunar mount the pen with write permission for the normal user.
EDIT : I took another USB pen and tested with NTFS partition then reformated to ext4 partition. NTFS partition works correctly, I can read and write. It is listed as so:
drwxrwxrwx 1 morpheus morpheus 4096 Jan 16 10:20 33C8B9D66F0C5779/
I then use gparted to reformat to an ext4 partition, I can no longer write to the pen and it is listed as so :
drwxr-xr-x 3 root root 1024 Jan 16 10:24 43ab54f4-c8de-4027-9c45-591f6bf84d08/
So the system mounts ext4 partitions as root and ntfs partitions as user. Where is this behaviour configured and can I change it ?
I don't really think I should have to edit my fstab every time I reformat a USB pen, or get a new pen. I just want the system to mount my external drives as user (not root). (There is no way grandma will edit fstab, she just wants to write to the darn pen !).
