ok, well since The dive is not connected to your system we need to mount it
You need to know the device that your external drive is seen as. In my case sda and sdb are the two internal drives. Any additional drives that I have are added to that (i.e. sdc, sdd, sde,...). So to mount the first partition of my external hard drive I use
mount /dev/sdc1 /Backup
For you I would think that it would be sdb1. A tool that I use to check sometime is Gparted. If you know how to install software on your machine easily I would suggest installing and running it. It will probe your hardware and display all the drives and partitions that it detects.
If you can't I would try assuming /deb/sdb1 and executing (as root!)
mount -t ntfs /dev/sdb1 [folder on your system]
if you don't get any errors than success!
Please post any error you get. I hope this helps
