"Error mounting: mount exited with exit code 1: helper failed with: Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root. Please see more information at http://tuxera.com/community/ntfs-3g-faq/#unprivileged",
do not despair. Did you install your system via USB? If so, check your /etc/fstab and see if you have something like this:
/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0
(can be also sdc1 and so on). Delete that line or comment it out (with #).That souhld work.
