Can't mount NTFS drive - "NTFS signature is missing."

I am unable to mount my NTFS drive on the latest stable Ubuntu Server 14.04 :

$ sudo mount /dev/sdc /media/wd3TbHdd -t ntfs
NTFS signature is missing.
Failed to mount '/dev/sdc': Invalid argument
The device '/dev/sdc' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Here is my fdisk output (edited to remove non /dev/sdc info) :

$ fdisk -l

...

I have 4 HDD's attached and one of them being a NTFS that works fine on my Windows machine but not here on my Ubuntu Server

You are trying to mount whole Hard Disk drive instead of Partition on it. Try mounting /dev/sdc1 instead of /dev/sdc.

sudo ntfsfix /dev/sdb2

solved my problem. I was trying for sudo ntfsfix /dev/sdb1. I guess I was pointing at a wrong partition.
