Ni! Connecting an external USB hard drive with an NTFS partition fails to mount it on both Gnome (Nautilus) and manually through udisksctl. On nautilus, it shows the partition but clicking on it pops a window: "wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error". I've managed to successfully mount it with my non-root user using udisksctl: $ udisksctl mount -b /dev/sdb2 -t auto Strangely, "-t ntfs" didn't work, but "-t auto" did the trick. Even when it worked, the drive is mounted without permissions for my user (uid 1000), though I could copy files with sudo.
