What power source does it run off of then?
You can't drive it from the Pi USB power, not enough there.

usb via usb hub it says in the first post the light on the hard drive comes on so i doubt its a power issue

Can't see that. You only say:

i have a 2tb ntfs external hard drive it does not run off its own power source but it still works

and that does not count as saying it is connected to a USB hub......

I'm a bit confused is your usb powered hard drive connected to a externally powered USB Hub ?

If it's not then you will get problems your hard drive will need to draw about 1000ma of power the raspberry pi usb outputs were originally only rated a 100ma however on the newer models the polyfuses have been removed but you can't expect it to power a big load.

If your usb hd is connected to a externally powered usb hub then we will try our best to help

Code:

sudo fdisk -l

shows what hard drives are recognised. Also

Code:

dmesg

should show something when you plug/unplug a hard drive.
