The relationship between the primary partition, the extended partition, and the logical partition h

There are three types of hard disk partitions: primary disk partitions, extended disk partitions, and logical partitions.

A hard disk can have one primary partition, one extended partition, or only one primary partition without an extended partition. Logical partitions can be several.

The main partition is the boot partition of the hard disk, which is independent, and it is also the first partition of the hard disk.

After the main partition is separated, the rest can be divided into extended partitions, usually all the remaining parts are divided into extended partitions, or not all of them, and the remaining parts are wasted.

However, the extended partition cannot be used directly, it is used in the way of logical partitioning, so the extended partition can be divided into several logical partitions. Their relationship is an inclusive relationship, and all logical partitions are part of the extended partition.

The capacity of the hard disk The capacity of the primary partition The capacity of the extended partition.

Capacity of Extended Partitions The sum of the capacity of each logical partition.

Your portable hard drive is not used as a system, so there is no need to divide it into any main partitions, you just need to divide it into several areas you want. However, I would like to remind you that the mobile hard disk is divided into 2 areas at most, because you have to use the mobile hard disk to read the data, the workload of the mobile hard disk will increase, which will reduce the life of the mobile hard disk. And it is best not to format the mobile hard disk frequently, otherwise it will break down quickly, after all, the workmanship of the mobile hard disk is not as mature as that of ordinary hard disks.

Partitions can be divided with PQ or PE bands.

A hard drive is divided into primary and extended partitions in that way. A logical partition is a logical area in an extended partition that is set up to facilitate the management of files. (Doesn't actually exist).

Primary Partition Extended Partition Logical Partition These concepts were useful in pre-XP systems. XP is useless after that.

For example, dos, win98In order for it to boot, it has to search for the boot file from the C drive of the main partition. Then the onboarding system boots.

However, the partition of the XP system will not have that kind of limitation. It is mainly divided into one functional partition. This is the role of the primary partition. (It can be any partition on your hard disk) install it into that partition with the original installation disk of XP, and that partition is the function partition.

320 portable hard drive partition does not have to worry about the main partition and other issues. Because you don't use it as a system disk, it's just a removable storage. Just divide it into a few according to your needs. Regardless of the difference.

Resolution: A physical partition is a disk space of the same size on a physical volume.

Primary Partition: Generally used to install your system The main partition can only be divided into up to 4, i.e.: hda1 hda4

The extended partition is relative to the primary partition, and when you divide the primary partition, the remaining disk space is divided into the extended partition!

A logical partition is a partition in the partition on the basis of the extended partition, and it can be divided up to "Z" (as long as your disk is large enough, as long as you need it), that is, from HDA5 onwards, all logical partitions are separated.

Note: "HDA1....n" is the name of a partition (drive letter) in Linux, which starts with the letter "C" in Windows and ends with "Z".

A" and "B" are usually assigned to floppy disk drives, so the partition of the hard disk starts with "C"! The drive letter name of the disc is assigned in "d z" (usually with a primary partition, i.e., "c").

A new hard drive.

1. Primary partition.

The main partition is also called the boot partition, and the Windows system generally needs to be installed in this main partition, so as to ensure that the boot automatically enters the system. To put it simply, the primary partition is a disk partition that can boot the computer to read files, a hard disk, up to 4 primary partitions can be created at the same time, when the four primary partitions are created, it is no longer possible to create extended partitions and logical partitions. In addition, the main partition is independent, corresponding to the first partition on the disk, and the vast majority of computers at present, when partitioning, generally divide the C drive into the main partition.

2. Extend the partition.

Extended partition is a concept that cannot be seen in the hard disk and cannot be used directly.

In addition to the primary partition, the remaining disk space is the extended partition. When a hard disk allocates all the capacity to the main partition, then there is no extended partition, only when the capacity of the primary partition is less than the capacity of the hard disk, the remaining space belongs to the extended partition, and the extended partition can continue to be expanded and cut into multiple logical partitions.

3. Logical partitioning.

On top of the extended partition, you can create multiple logical partitions. A logical partition is equivalent to a storage cut-off, which has nothing to do with the operating system and other logical partitions and primary partitions, and is "independent".

The difference between primary, extended, and logical partitions.

Most computers are divided into a C drive main partition, and then the other D drives, E drives, and F drives belong to logical partitions, and the combination of D drives, E drives, F drives, etc. out of the main partition belongs to an extended partition.

When creating a partition on a new hard disk, the following order is generally followed:

Create a new [Primary Partition] and then create an [Extended Partition] In the extended partition, create a [Logical Partition] and then activate the [Primary Partition] Finally, format all partitions and you're done.

The main partition of the hard disk is simply understood as the system partition, which is used to install the system.

Logical partitions can be thought of as being used to install and store files.

Let's be honest. The corn system is relatively stable and smooth.

A primary partition, also known as a primary disk partition, is a type of partition just like an extended partition or a logical partition.

The primary partition can no longer be partitioned.

other types of partitions, so that each primary partition is equivalent to a logical disk (in this respect the primary partition is similar to a logical partition, but the primary partition is partitioned directly on the hard disk, and the logical partition must be built in the extended partition).

In the early MBR mode, partitions could only be divided into four partitions, but now GPT partitions can be divided into at least 128 primary partitions, and it is very likely that the concept of extended partitions and logical partitions will not exist in the future.

They are all partitions used to store data, but because the previous conventional MBR disk partition ** disk can only record 4 partition information in the MBR record, that is to say, it can only support 4 primary partitions, which cannot meet the needs of larger and larger hard disks. In order to solve this problem, the concept of extended partition is proposed, which is a special primary partition, in which multiple partitions can continue to be divided, which is a logical partition.

In fact, even if it is your hard disk, there is only one main partition, that is, the disk where your system is located, and the others are logical partitions, and the mobile hard disk is of course a logical partition.

It doesn't matter. If you want to use a portable hard drive as a boot tool, you need to use the first partition as the primary partition and activate the active partition.

The logical primary partition is the partition where the system disk is located.

You can create only one logical partition in an extended partition.

The differences between the two are as follows:

First, the reference is different.

1. Primary partition: also known as the primary disk partition, which is located in the front area of the hard disk and constitutes a logical C disk.

Second, the characteristics are different.

1. Primary partition: No other types of partitions can be divided into partitions, so each primary partition is equivalent to a logical disk (in this regard, the primary partition and the logical partition are very similar, but the primary partition is directly divided on the hard disk, and the logical partition must be established in the extended partition).

Third, the role is different.

1. Main partition: The main boot program is a part, this section of the program is mainly used to detect the correctness of the hard disk partition, and determine the active partition, which is responsible for handing over the boot right to the DOS or other operating systems of the active partition. If this program is corrupted, it will not boot from the hard disk, but it will be able to read and write to the hard disk after booting from a floppy drive or optical drive.

2. Extended partition: Extended partition cannot be used directly, but is used in the form of logical partition, so extended partition can be divided into several logical partitions. Relationships are contained relationships, and all logical partitions are part of the extended partition.

Absolutely. The extended partition is a special primary partition, in which a logical drive (commonly known as a logical partition) can be created, and the number of logical partitions is not limited, but there must be at least one, because the extended partition cannot be used directly, it is only used to accommodate the logical partition, and there can only be one extended partition on a hard disk.

In the early days (DOS or win98 years), if there were two (or more) primary partitions on a hard disk, the system did not know which primary partition to boot from, so the habit at that time was to create a primary partition (install the system) first, and then create all the remaining capacity as an extended partition, and then create multiple logical partitions in the extended partition for use. Nowadays, the system is not subject to this restriction, so if you don't have more than four partitions on one hard disk, there is no need to create an extended partition, just create the primary partition.

Yes, there is a PE system.
