I have a HP Chromebook where i used crouton to install xfce on. Everything is working fine and expected. However when I whenever I plug up a flash drive (64bit formated with NTFS or 265MB formated with FAT32) I see the stick pop-up in the file explorer (Thunar) for a second and then immediately disappear before I could have time to click on it (similar like here).

When I try the sticks in the default ChromeOS they work and are auto-mounted. So I think my issue is that ChromeOS auto-mount the stricks in the background while I´m using xfce.

If I try (inside xfce):

sudo mount /dev/disk/by-uuid/80F43972F3583C0B /home/user/64GBUSBStick

Then I get the error:

Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the fuser command

However for the FAT32 stick its working ...

This might be (sorry if wrong, but I´m not a linux pro) due to the reason that when checking with


that the devices can be both seen here:

/var/host/media/removable/64GB or /var/host/media/removable/265MB

However they where still not added to Thunar

Did anybody have a solution for that issue? My preferred one would be to keep both auto mount options up and running if possible.


Found the issue after some days troubleshooting on my own: The problem is that Google Chrome auto mount the USB stick while xfce is only a kind of 2nd OS. So once Google Chrome stopped to auto mount the USB stick it will stay mounted in Thunar.
