Can you unlock a partition in external HDD? (NTFS)

[Vista_Nueva]

I had at first made my external 1 big 250gb partition, but I want to shrink that partition. but when I use the Ubuntu partitioner (my only option I think) it shows a padlock and won't let me resize. How can I get this to change?

Try GParted (Free), also in LiveCD or Partition Magic.
