It mounts in Windows and Linux on this same box. This is what dmesg reports when it is attached:

Is fuse loaded ? check with kldstat | grep fuse

Try

Code:
mkdir /media/usb
/usr/local/bin/ntfs-3g /dev/da5s2 /media/usb

First, you need to install fusefs-ntfs by pkg and load it in loader.conf.
use dmesg to find the name of your external USB.
you can use gpart to show of partitioning of your USB.

It can happen if the NTFS filesystem is dirty (at least the NTFS equivalent of a 'dirty' filesystem).

Correction: The native (Windows) implementation of NTFS is perfectly stable and good. Doesn't have many of the data safety features (that are for example available in ZFS), but it is a fine local file system. The problem lies with the reverse-engineered NTFS implementations that are found in OSes other than Windows, in particular in the ones that have to use fuse; those I would stay away from for data where reliability is important. Note that this observation is not specific to NTFS; quite a few other file system implementation that are based on things like reverse engineering should not be used in high-reliability production.

fuse loaded, ntfs installed, Linux and Win7/10 have no issues mounting the drive, holy wars skipped.
