Upon further investigation I found an explanation from the SuperUser forum and it corrected the problem.
Look through your /media folder. My guess is that even when no drive is plugged in, its mountpoint exists. remove this (empty) directory (with the drive unplugged, just to be safe), with sudo rm -r /media/drivename. Hopefully that will fix it. ...because the Gnome automounter creates a new /media/drivename mount point for stuff it automounts (and deletes it when unmounted). so if the default exists, the automounter will append the underscore to get a mount point that doesn't exist. (i suspect the existing mountpoint will be used if there's a corresponding /etc/fstab entry for it. but i haven't tested this theory.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/119183 Title: Underscore character is appended to mount directory name of USB disc after hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hal/+bug/119183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
