I have free space on the disk but I can't add that space to the ubuntu partition, gparted doesn't let me resize the ubuntu partition at all.
I'm running the livecd 14.04 LTS, my ubuntu version is 15.04

sda1 and sda2 are the windows partition sda3 is my data partition
I want to shrink my data partition (sda3) by around 50gb and add that 50gb to my ubuntu partition (runnning low on space frequently)
I can't add that free space to the sda4

The free spaces must be next to the partition you want to resize, and all the partitions must not be mounted, even the swap partition (select swapoff)
