Comment 4 for bug 40561

I have the same problem with the w810i as marduk above. I also tried to make a new vfat-filesystem on /dev/sda1 or to remove module ehci_hcd, both with no success.

Sometimes it helps to do a umount /dev/sda1 and using the eject-dialog of gnome only when this is done (takes a while, depends on the size of the copied files).

Thanks and best regards,
