Primary partitions, extended partitions, and logical partitions in Windows

Primary partitions, extended partitions, and logical partitions in Windows

There are three hard disk partitions,Primary Partition,Extended partition,Logical Partition.

[1] Primary Partition

The primary partition is the boot partition of the hard disk, which is independent and the first partition of the hard disk. Normally, the C disk is used. The primary partition can also be a "Boot partition ",

It is determined by the operating system and the motherboard as the first partition of the hard disk.

[2] extended partitionsExcept for the capacity occupied by the primary partition, the remaining capacity is considered as an extended partition. In general, the primary partition is the master of the hard disk, and the extended partition is the servant of the hard disk. The primary partition and the extended partition are the master-slave relationship. [3] logical partitioningExtended partitions cannot be used directly. They are used as logical partitions. Therefore, extended partitions can be divided into several logical partitions. Their relationships are contained, and all logical partitions are part of the extended partitions. It is equivalent to dividing a servant into a number (D Drive), a number (E drive), and a number (F drive.
A logical partition is a continuous area on a hard disk. The difference is that each primary partition can only be divided into one drive, and each primary partition has its own boot block. A hard disk can have a maximum of four primary partitions, and multiple logical drives can be divided into extended partitions. These logical drives are not independent Introduction Import BlockCannot be set as the boot zone. [4] MBR Mode Master Boot Record. When you associate it with a partition, it indicates a partition standard. Because only 64 bytes of storage space is reserved for the partition table in the Master Boot Record of the hard disk, and the parameters of each partition occupy 16 bytes, the master partition can only store data of four partitions in total. That is to say, a physical hard disk can only be divided into four primary partition disks. In addition, MBR supports a maximum of 2 TB hard disks. In this era where 4 TB is not uncommon, chances of playing MBR are getting fewer and fewer ( GPT Mode). [5] Description in MBR mode, a hard disk has at least one primary partition and a maximum of four primary partitions. Extended partitions can have at most one primary partition. The total number of primary and extended partitions cannot exceed 4 (because the extended partition also occupies one boot block ). There can be several logical partitions. In GPT mode, there can be at least 128 primary partitions.

Hard disk capacity = primary partition capacity + extended partition capacity

Capacity of extended partitions = total capacity of each logical Partition

The active primary partition will become"System PartitionThe system partition contains hardware-related files and Boot folders. You can use this folder to obtain the Windows Startup location. By default, if Windows 7 is installed on an unpartitioned hard drive, a separate system partition is created.

The partition size is 100 MB (also the primary partition type ).

Start PartitionIs a partition that contains Windows operating system files. For example, if there is a multi-boot computer that contains Windows

Vista, which contains Windows 7 on another volume, considers both volumes as startup partitions.

The system partition and boot partition are the names of the partitions (or volumes) on the hard disk. Windows uses this hard disk when it is started. System partitions actually contain files used to start Windows 7, while startup partitions contain system files.

You can usePartition AssistantModify and adjust the primary and logical partitions of a hard disk, such as converting the primary partition into a logical partition, merging and cutting partitions.
