cfdisk shows the size of the partitions, whereas df shows the
size of the filesystems. It would seem that the filesystem on
hda4 doesn't fill the entire partition. Something like

 # umount /mnt/data
 # resize2fs /dev/hda4
 # mount /dev/hda4 /mnt/data

should fix this. resize2fs will automatically resize to the
size of the partition if no size option is given.
I'm not sure whether resize2fs can resize mounted filesystems. It
couldn't last time I used it, but that is some years ago.
