What does primary partition mean?
Question 1: What do primary partitions and logical partitions mean respectively, and what are their respective characteristics? There are three types of hard disk partitions: primary disk partition, extended disk partition, and logical partition.
A hard disk can have one primary partition and one extended partition, or it can have only one primary partition and no extended partition. There can be several logical partitions.
The primary partition is the boot partition of the hard disk. It is independent and is also the first partition of the hard disk. Normally it is the C drive.
After dividing the primary partition, the remaining part can be divided into extended partitions. Generally, the remaining part is divided into extended partitions, or not completely. The remaining part is wasted.
However, the extended partition cannot be used directly. It is used in the form of logical partitions, 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
The capacity of the extended partition =The sum of the capacities of each logical partition
The primary partition can also become a "boot partition", which will be recognized by the operating system and motherboard as the first partition of this hard disk. Therefore, the C drive will always be ranked first among all disk partitions.
In addition to the capacity occupied by the primary partition, the remaining capacity is considered an extended partition. In layman's terms, the primary partition is the master of the hard disk, and the extended partition is the slave on the hard disk. The primary partition and the extended partition have a master-slave relationship.
If the extended partition is no longer partitioned, then the extended partition will become a logical partition. If partition operations are also required, the so-called logical partition can only be operated from the extended partition. It is equivalent to subdividing the servants (on the extended partition) into those who answer the phone (D drive), sweep the floor (E drive), cook (F drive) and so on.
Therefore, the relationship between extended partitions and logical partitions is equivalent to a reclassification relationship.
Based on the above opinions

Question 2: Computer owner What does it mean to have more than two partitions? Usually, computers only have one primary partition (the one that can be booted).
Sometimes, special software can be used to set up two or more primary partitions.
At startup, choose to enter. Because the different uses do not affect each other.
But the data area (other partitions) can be accessed. The two of them usually cannot access each other.
If you want to change this situation, it is more dangerous. It is easy to cause the entire hard disk to be unrecognized, the partition table to be incorrect, and all data to be destroyed.
The safest way is to back up important data in other partitions first (to another physically existing hard disk).
Use the software that you originally set up with multiple primary partitions, and change it to one primary partition.
Because the person who untied the bell must also tie the bell, which is relatively the safest and most reliable.
If, you cannot find this software. or inoperable.
Just find a computer veteran to help you solve it. Note that this is not a veteran who uses it, but a hardcore veteran who can often install systems, partitions, and restore data levels. to help you operate.
If it doesn’t matter what you have, as long as you can reinstall the system.
Then, after backing up the data, use any software to delete all partitions, re-create the partitions you want, and format all drive letters.
Then, install the system on the only primary partition, and finally restore the data you backed up.
In the past, the more famous partition software was: Norton PartitionMagic

Because, a few days ago, when I used GHOST to copy the hard drive, I made a mistake and overwritten a hard drive. I found it using it, and not a single byte was lost. I don’t know what to say with excitement. That’s more than 6 G of data. Of course, you have to retrieve the data and put it in a non-C: partition, otherwise it will be over. So I trust it more. It is made in China and operates under Windows. Pay attention, when looking for the partition table, if it is not there, don’t move it until you have actually found it. Be cautious and understand before taking action.
Question 3: What does the logical partition of the primary partition of the hard disk mean? Is the primary partition the default c drive? The primary partition is usually where the system is installed.
If you only install one operating system, it must be installed on the primary partition! Otherwise it will not start. When installing two or more operating systems, one operating system should also be installed on the primary partition.
Primary partition and logical partition: For example, when partitioning the hard disk in DOS. The primary partition means that after you partition the hard disk, select the option under the partition command (I seem to have forgotten it. I haven't partitioned it for a long time) and set the logical disk you want to set as the primary partition to 1. That is the activated partition. This is the primary partition. The other ones you have not activated are logical partitions. It is not necessary that the system is installed in the primary partition. You can use the DOS transfer command to transfer system files to the primary partition and start it. I'm not sure if it's harmful to computers. Because I only transfer files to start when there is a problem with the computer. At that time, there was a system in the logical partition, but there was a problem.
Question 4: What is the purpose of converting the primary partition of the hard disk into a logical partition? What is the primary partition for? What are logical partitions used for? The main differences are in two points: the primary partition can be used as a boot partition but the logical partition cannot; one primary partition corresponds to one disk but the logical partition can be divided into multiple logical disks. The system can be installed on both main and logical points.
Question 5: What is the difference between the primary partition and the logical partition of the hard disk? Primary partition, extended partition, logical partition
The primary partition of a hard disk is the hard disk partition that contains the files and data necessary for operating system startup. The operating system must be installed on the hard disk. , then the hard disk must have a primary partition.
The extended partition is a partition other than the primary partition, but it cannot be used directly. It must be divided into several logical partitions. Logical partitions are the D, E, F and other disks we usually see in the operating system.
No matter which partitioning software is used, we must follow the following sequence when creating partitions on a new hard disk: Create a primary partition → Create an extended partition → Create a logical partition → Activate the primary partition → Format all partitions .
Question 6: What is the difference between primary partition and active partition? The difference is that there can be multiple primary partitions, but there can only be one active partition.
An active partition means that the primary partition is active. A hard disk can have multiple primary partitions, but there can only be one active partition, which is the primary partition currently in use.
Question 7: What is a primary partition? Why can there be more than one? Primary partition is a disk type that can be created on a basic disk. It is relative to extended partitions and logical partitions. The concept of partitioning.
In the MBR partition mode, the hard disk can only be divided into 4 partitions, and 4 partitions are definitely not enough, so the concepts of extended partitions and logical partitions were born, and the previous partition types were named Primary partition. In fact, in the early hard disk partitions, there was no concept of primary partition, extended partition and logical partition. The type of each partition was what is now called a primary partition.
Question 8: What are the differences, benefits and impacts between the primary partition and the logical partition in Win7? First of all, the primary partition and the logical partition are not unique to the Win7 system. They are the differences between the Windows operating system and the hard disk. Partitioning method.
The biggest difference between primary partitions and logical partitions is that there can be up to 4 primary partitions on a hard disk, while there can be only one logical partition at most. Furthermore, primary partitions can be used to boot the system but logical partitions cannot.
This does not matter whether it is good or bad. It depends on personal preference. If your computer has only one system, you can only divide it into one primary partition. If you want to install dual systems, then divide it into two primary partitions.
Question 9: What does system, activity, and primary partition mean? Is my computer like this now? (See the picture) The h drive used to be the only hard drive and the c drive. On top, is the system disk. A hard disk can be divided into three primary partitions and one extended partition. The extended partition can be defined into several logical partitions. Only one of the three primary partitions can be designated as the active partition, so that when the computer starts, it will only look for the system in the slave partition. The active partition and primary partition can only be changed in the partition software and cannot be changed by formatting.
Question 10: What does the active partition of the computer hard disk mean? Each area partitioned by a hard disk is called a "partition". They have their own independent disk codes and their own independent storage areas. They are used as if there are multiple hard drives. However, depending on the functions, the nature of the partitions is also somewhat different. A primary hard disk can be divided into three types: Primary (primary partition), Extended (extended partition), and Logical (logical partition).
1. Primary partition
If you only have one hard drive, then this hard drive must have a primary partition. In the past, DOS had to be in the primary partition to start. The biggest purpose of creating a primary partition is to install the operating system. In addition, if you have multiple primary partitions, only one can be set as the active partition (Active). The operating system is booted from this partition. Of course, only one is allowed to be active. Partition, the so-called "activation partition" is to set a primary partition as the active partition.
2. Extended partition
Because the primary partition has inherent limitations (there can only be 4 at most), extended partitions came into being to solve this limitation, but you need to remember The catch is: it cannot be used directly to save data. The main function of the extended partition is to allow you to create logical partitions in it, and in fact only more than 20 can be created.
3. Logical partition
From the above introduction, you can understand that the logical partition is not an independent partition. It is a secondary partition built in the extended partition, and in DOS Under /WINDOWS, such a logical partition corresponds to a logical drive (Logical Driver). What we usually call D: E:... generally refers to this kind of logical drive.
4. Partition restrictions
A hard disk can only be divided into 4 primary partitions at most, or 3 primary partitions plus an extended partition. This is because at the beginning of the hard disk , that is, 0 head, 0 cylinder, 0 side, 0 track, 0 sector, a total of 512 bytes store the most important information of the hard disk, MBR (Master Boot Record (Master Boot Record) and partition-related information. Since the recording space is only so large, only the information of these 4 partitions can be recorded.
