A disk could be partitioned into for primary partition and multiple logical partitions. However, along with the increasing use of disk partitions, a large amount of data would inevitably be packing those partitions, resulting in insufficient disk space, poor partition performance and tardy computer operating speed. In this sense, it becomes acutely urgent for user to extend the partition space. To realize this operation, user should always turn to a third-party partition manager, for example, MiniTool Partition Wizard.
Logical partition is a part of successive areas on hard disk and each primary can merely be divided into on drive with each primary possessing its independent boot block which can be set as boot partition.
There are in total three types of partitions for hard disk: primary partition, extended partition, logical partition.
A hard disk should have minimally one and maximally 4 primary partitions, none or at most one extended partition and no more than 4 partitions with both primary partition and extended partition combined.
The activated primary is the hard disk boot partition, which is independent and the first partition of hard disk.
