Disk Management Utility has disadvantages but for basic tasks it's very helpfull. As IT i have use it lot of times. I don't recommended to do very advance tasks with PARTITIONS because it's very dangerous to destroy a disk or partitions which you don't. So Disk Management Utility can cover all of my tasks with partition.
