Ok, I suppose you're running kubuntu gutsy so I think you you should
have ntfs-3g installed by default. Do a 
sudo apt-get install ntfs-config

To see what we're talking about the link is:
http://flomertens.free.fr/ntfs-config/screen.html

Check "Enable write support for external device" and see if anything
changes. It might not.

If it doesn't, and if when you plug your disk you see a window
complaining about permission denied - but try it all the same ;) - in
konsole run this command:

sudo mount -t ntfs-3g /dev/whateveritis /media/disk-[n°]-o force

Before you do, check how your disk gets named. In my case it was sda1
and the command was

mount -t ntfs-3g /dev/sda1 /media/disk1 -o force

It it works, you might want to add a line in /etc/fstab.

You can also find a few discussions, some of them quite recent, if you
search the list for "ntfs usb mount".
