Kubuntu 12.10 not seeing usb drive formatted ntfs

view story

http://askubuntu.com – I have a 160gb hard disk (model WD1600BEVT) that I've installed in a USB casing. I formatted it as NTFS in Windows 7. A few days ago, I have installed Kubuntu 12.10 on my computer at home, but when I connect my USB NTFS drive, it doesn't detect it: "sudo fdisk -l" doesn't see it at all. What should I do to mount it? Can I make it automount when plugged? Thanks! (HowTos)
