This indicates that something else has mounted your device. The below is just asking for an administrator password. > A application is attempting to perform an action that requires privileges. > Authentication is required to perform this action. > > Password: [ ] > > Details > Action: org.freedesktop.udisks2.filesystem-unmount-others > Vendor: The udisks Project > ---------------------------------------------------------------------------------------- > > Upon entering the password I get this message: > > ---------------------------------------------------------------------------------------- > Volume is busy. > > One of more applications are keeping the volume busy. > rsteff@Enu-1: /media/usb0/DCIM > [Cancel] [Eject Anyway] > ---------------------------------------------------------------------------------------- You can try to find out what is holding the device open with lsof, and that might hint at what was used to mount it, and then troubleshoot things from there. Eject Anyway could lead to a dirty umount or a broken shell / utility when it can't see the device any longer. > I hit [Cancel], switched to a different directory in Nautilus and tried > again.

Keep plugging at it. You may also want to continue to do web searches on resolution with other means, and possibly confirm which group associations your user needs to be a member of for this to all work properly. dafr _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
