Error mounting /dev/sdb1 at /media/ on Ubuntu 14.04 LTS

How I can fix the Error mounting /dev/sdb1 at /media/... It works pretty good in the past but I made a clean installed of Ubuntu 14.04 LTS and the Error mounting coming. I try to fix it with with Gparted, ntfs-3g, pmount, but this programs can't find the external HDD. But when I boot put the USB drive with Ubuntu 14.04 on test mode this can find and read my external HDD. How I can fix it?

Solution 1:

open terminal with Ctrl+Alt+T and run

sudo ntfsfix /dev/sdb1 

Solution 2:

Run this command to show disks:

lsblk

Run this command to mount usb:

sudo ntfsfix /dev/sdb

/dev/sdb or /dev/sdb1 or some other path
