Only 4 partitions are allowed on a disk. The way around is to create an extended partition and create logical partitions within it. I always use linux tools to partition.
But the PM tool recommended will allow you to resize partitions without losing data - if you do it carefully. I always keep a notepad and pencil the cylinder/sector numbers down to avoid mistakes. (used to rather... hiding my recent personal disasters actually
