How many primary partitions can be on the disk. Types of logical partitions of a hard disk. Creating a separate section

Before proceeding to the story of the parameters of the response file that control the creation and formatting of the partitions of the hard disk, I would like to set out some basic sections. In addition, I will touch the terminology issues, which should also help you deal with the parameters of the responses file, which are called in English. If you consider yourself a fairly experienced user (well, of course, you think :), you can skip the first section of the article.

Introductory information about the partitions of the hard disk

As you know, a new one, which has just taken out of the box of a hard disk that is customary to call physical diskFrom the point of view of operating systems and programs is an unbalanced space. In order to install OS or use the file storage disk, you need to create at least one on it. section. In English, the section is called partition.So some people call partitions partitions.

On one physical disk you can create several sections. As a rule, sections are created in order to be able to install multiple operating systems or transferring user files to a section other than the on which OS is installed. There are two types of sections - main (Primary) and additional (extended). There may be no more than four main partitions on the disk, and if there is an additional partition of the main sections, there may be no more than three. The optional section acts as a container in which you can create one or more logical disks. The difference between the main and additional sections is that the main partition can be used for launch The operating system, and with the logical disks of the additional partition, it is impossible to start the OS. The section on which the files need to start the operating system are marked and called active. On the physical disk there can be only one active section. A section containing system system files Windows, called bottlingAnd such partitions may be somewhat (for example, in configurations with several installed OS).

In the screenshot, you see the main and optional sections (one logical disk is created on the additional section).

When creating a section, it is assigned letter. The first section of the first physical disk is assigned a letter C, the second - D, and so on, following the English alphabet. First, the main partition is created, and the additional (if necessary) already follows it, after which, in principle, other main sections can be created. To use an additional partition, you need to create at least one logical disk. He and the following logical disks will also be appointed letters in alphabetical order.

To install the OS or placement of files on a section or logical disk it must be formatted. In Windows, the NTFS and FAT32 file systems are used. Installing Windows Vista is possible only to the section formatted in NTFS. Formatted main section or logical disk is called tom. This can be prescribed labelwhich will be displayed, for example, in the window My computer.

Before you start configuring a hard disk, you need to determine how many sections or volumes you want to have on it as a result. If not more than three, it makes sense to create only the main sections. Subsequently, it will be easier to work, if you need, for example, combine two sections in one. In the Windows Vista disk management tool, it will be easy to do, but the union of the main partition with the additional is a non-trivial task.

I hope that now you are fully prepared to configure the parameters of the hard disk partitions in the answer file for Windows Vista.

Adding components responsible for configuring hard disk partitions

Unlike Windows XP, the Windows Vista installation program allows you to configure the creation and deletion of partitions on the physical disk. To perform these operations to the responses file, add multiple components.

Add the following components to the response file.

Component		Pass
Microsoft Windows-SETUP \| Diskconfiguration \| Disk \| CreatePartitions.	-->	1 Windowspe
Microsoft Windows-SETUP \| Diskconfiguration \| Disk \| Modifypartitions.	-->	1 Windowspe
Microsoft Windows-SETUP \| ImageInstall \| Osimage \| InstallTo.	-->	1 Windowspe

Editing response file parameters

To create sections, it is necessary to have an unbalanced space. In this article, I will consider an example of creating two sections - the main and optional. An additional section will create one logical disk. If you need to create more major sections or more logical disks, you can do it by analogy.

Attention! Example is considered full removal of all sections of the physical disk Before performing the creation and formatting operations of new sections. Please do not use for experiments with data with data that you feel sorry to lose.

From the point of view of logic, the order of working with the parameters of the responses file is approximately the same as if you work with the partitions of the hard disk interactively. To perform the task assigned in the example, you must perform the following operations.

Delete all partitions on the disk.
Create a main partition.
Create an additional partition.
Create a logical disk on an additional section.
Set the file system format for a partition or logical disk, as well as the drive letter and volume label.

Delete all partitions on the disk

windowspe | Microsoft Windows-SETUP | Diskconfiguration | Disk ("0")

Component Disk ("0") Responsible for the overall configuration of the first physical disk.

Diskid - disk identifier. Value 0 denotes the first physical disk
Willwipedisk. - Delete all partitions of the hard disk. Attention! If set is set true.All sections will be deleted. This value must be set to perform the operations described below in the article.

Creating partitions on disk

windowspe | Microsoft Windows-SETUP | Diskconfiguration | Disk ("0") | CreatePartitions.

With this and component (and its subsidiaries) sections are made. Right-click on the component CreatePartitions. Insert a new createpartition.

Perform this action for another twice so that you have three components CreatePartition. Why are three? Because for the configuration in our example, you must perform three operations - create a main partition, an additional partition and logical disk on an additional section. If two main sections were created, there would be enough two operations.

Creation of the main section

Click the first component CreatePartition

Extend. true.The section will be expanded. If set is set false, You must specify the size using the parameter Size.
Attention! For each section, the value of the parameter is set. Extend.or the value of the parameter SIZ.e, but not both. Since the example is planned to create more than one partition, the extension is not used ..
Order - Sequence number of operation to create a partition on the disk. Numbering begins with a unit. In the example, the value is indicated 1 , i.e. the section will be created first.
Size - section size in megabytes. The example creates a section of 50,000 MB, which is just less than 50 GB. Specify the size of the partition at your discretion. Since Windows Vista is installed on the first partition, do not make it small. The minimum requirement for installing this OS is a 40 GB hard disk, so it is not recommended to create a smaller partition.
Type - section type. You can create a basic ( Primary) or extra ( Extended) section. In this example, the first section will, of course, the main one.

Creating an additional section

Click the second component CreatePartition In the list and set the parameters for it.

The second section in this example is an additional, and it is the last (more sections are not planned to create). So that he took all the remaining free unimpressed space for the parameter Extend. Set value true. (and parameter Size Not set). The section will be created second, reflected in the parameter value. Order. Finally, an additional partition is created, so for the parameter Type Indicates value Extended.

Creating a logical disk on an additional section

Click the third component CreatePartition In the list and set the parameters for it.

Since only one logical disk is created on the additional section, it should take all the available free unimpressed space. Therefore, for the parameter Extend. Set value true. (and parameter Size Not set). Since the logical disk is created for the parameter Type Indicates value Logical..

Set the file system format, drive letter, volume labels, etc.

For each created partition and logical disk, you need to specify a number of parameters, such as the file system format, a disk letter, etc. These operations are performed using a component. Modifypartitions. and its subsidiaries. This component can be used not only to configure the parameters of newly created partitions, but also to change the parameters of sections that exist on the physical disk.

Right-click on the component Modifypartitions. and select the command from the context menu Insert a new modifypartition.

Perform this action for another time you have two components Modifypartition. Why two? Because for the configuration in our example, you must perform two operations - set the parameters for the main partition and logical disk on the additional section.

Click the first component Modifypartition In the list and set the parameters for it.

Active. - Assigns the section active. For assignment, True is used. Since on the main section (namely, we are now configurable - this is set by the parameter Order) Windows Vista will be installed, this section should be appointed active.
Extend. - Expansion of the partition to the size of the entire free unimpressed disk space. If set is set true.The section will be expanded. You have already seen this parameter when creating a partition. Since component Modifypartition You can also use to change the parameters of sections already existing on the physical disk, parameter Extend. Available here. However, one should not expand the section that the expansion has already been specified when creating. Moreover, in our example we set a fixed size for the main partition. Use the value false For this parameter.
Format. - File system format. Installing Windows Vista is possible only on the NTFS file system.
Label - Tom label. Set at your discretion.
Letter. - Disc letter. Logically set for the first partition letter C..
Order - The sequence number of the section change operation. Numbering begins with a unit. In the example, the value is indicated 1 , i.e. the section will be changed first. Obviously, the sequence number of the operation change The partition in this case must comply with the sequence number of the operation creation section.
Partitionid. - The identifier of the section, in fact its serial number. Numbering begins with a unit.

Click the second component Modifypartition In the list and set the parameters for it.

Since the logic disk parameters are specified on the additional section, the value for the parameter Active. Must be false (In addition, the active section on the physical disk can only be one, and we have already prescribed it). The remaining parameters were discussed above.

On this operation to create and modify partitions of a hard disk can be considered complete. But this is not the end of our history - to configure a few more parameters.

Microsoft Windows-SETUP | ImageInstall | Osimage | InstallTo.

Configuring component Osimage. and his subsidiaries InstallFrom. and Metadata. Considered in the previous article. Therefore, it remains to deal with the subsidiary component. InstallTo.. From his name it follows that it indicates where to install Windows Vista. Indeed, with it, you can specify the number of the physical disk and the section number for installation.

In this example, the operating system will be installed on the first section of the first physical disk. Note that the numbering of physical disks starts from scratch, and the numbering of partitions on the disk - from the unit.

Note. Component InstallTo. It is necessary to configure if the component Osimage. parameter InstallToavailablePartition has the meaning false.

Important note on configuring hard disk partitions

You probably noticed that the installation program you need to accurately specify the number of the physical disk and the section number for installation. This is an easy task if a single physical disk is installed in the system. However, in configurations with multiple hard drives, and even connected to different interfaces (IDE and SATA), to determine in advance the partition number may be difficult. Considering the fact that the installation program is configured to remove all sections from the physical disk, calculating, you can lose everything with unbearable difficulty. In this regard, for configurations with multiple hard disks, it is recommended not to automate the process of creating and formatting sections, but to perform it manually.

XML code fragments for various hard disk partition configurations

In the article, examples are given by several XML code fragments for the section Replies file. Each fragment is a complete partition configuration script. I recommend that you first create a response file using WSIM, and then compare its contents with these fragments to make sure that you correctly understood the principles of working with sections during Windows Vista.

So, we have all the parameters of the response file, including the configuration of the hard disk partitions. Now, you can go to the article in which the verification is considered and saving the answer file, as well as the issues of its placement.

Sections of a hard disk (they are called volumes, they are partitions from English Partition) can be the main and logical. Another name of the main type of disk section is primary. Main (or primary) disk partitions are used to start the operating system. This is a system partition with where Windows is directly installed, and a small section with reserved space (100 MB, 350 MB or 500 MB), which, starting with version 7, is created for the needs of the operating system. The logical sections of the disk from the main are not functionally different. What is the main ones that on the logical sections of the disk - and there, and information is stored there. The difference is that the launch of Windows is not possible from the logical disk partition. If you turn the system partition from the main one in logical, Windows is not in all, but in most cases it will be able to fully function fully.

But in all in a row, it does not want to boot, if it is logical to make it a technical small section with a reserved space, where, in particular, the download data is stored.

Below in the details will talk about the essence of the main and logical partitions of the hard disk, as well as consider ways to transform them from one to the other and vice versa.

1. The limit of the number of major partitions on the disk

On one hard disk should be no more than 4 main sections, if there is no logical. If the need to create more than 4 sections of the disk, the 4th section created and all subsequent sections must be logical. So, after the three main sections created, the 4th section, called additional or extended, will be a container, which, in turn, can be divided into many logical partitions.

2. Formation of basic and logical sections

The standard Windows disk management utility does not provide the user with the ability to select the type of disk section. The utility itself provides optimal alignment for most cases. The first 3 sections created by it are basic default. And, starting from the 4th, all partitions created by the utility are automatically created as logical.

According to the same principle, the third-party disk space manager is also working - the Aomei Partition Assistant program. The first three sections with default settings are created as basic, and, starting from the 4th - as logical. But, unlike the Windows Utility, Aomei Partition Assistant provides advanced mode for creating a disk partition where you can manually select the first three of the main or logical type partitions.

Another configuration reader is a Paragon Hard Disk Manager program. Its default disk partition creation settings are also sharpened to form the first three sections as the main one. And, as in the previous program, when creating the first three sections, you can manually change the pre-installed basic type to the logical, meaningful in the program as advanced.

But the program Acronis Disk Director template parameters does not adhere to. The form of creating a new disk partition by default provides for the creation of a logical partition. Section type parameters must be reassigned manually - to create the main partition, respectively, put ticks near the inscription "Main" and near the inscription "Active" if a section is formed for Windows.

3. Why change the logical section of the disk on the main and vice versa

When can there be a need to change the logical type of disk partition on the main and vice versa? The need to conduct the first operation is, as a rule, the very cases of unsuccessful experiments with the conversion of Windows system partitions from the main logical. These are also cases of problems with installing Windows when only logical partitions were created on the hard disk.

The need for a reverse operation - in converting the main partition to logical - occurs when the main partitions on the disk turns out to be greater than necessary for specific situations. For example, in the case of Windows recovery from a backup to a section other than the source. We are talking about the transfer of the system to another, the already distributed hard disk, where it is necessary to save the structure and data of non-system sections, and on the system partition to restore from the backup "Clamp" Windows. If a hard disk has 4 basic sections without logical or 3 basic, and all other are logical, programs for backup in some cases will refuse to perform the operation to restore Windows. Since the backup can contain a non-one system section C, and also mentioned above the technical section with a reserved space for the needs of Windows. This small section and system section with the completion of the recovery operation, whether it is possible, would be divided by the main destination section into two sections, and also the main. And thus would have violated the rule - or 4 of the main sections without logical, or 3 main sections, and all other logical. In this case, the problem is solved like this: one of the non-system sections where the user data is stored is converted from the main thing in logical, which, in fact, it must be.

4. Installing Windows to the logical section of the disk

If there is basic partitions on the hard disk, even if Windows is purposefully installed on the logical partition, the operating system itself during the installation converts it to the main one. Windows will even get out of the situation when the limit of the main sections will be exhausted. It will simply develop a technical partition on any available main section.

But if only logical partitions are on the hard disk, Windows will not want to install Windows at the disk partition selection phase. The easiest thing will be the case if there is no data on the disk or they do not imagine importance. In this case, the problem is easily solved by the screwdriver tools for the installation disk of the operating system. Existing logical partitions of the disk are removed by the "Delete" button,

and new sections are generated in their place using the "Create" button.

On the Windows 7 installation disk to access these buttons, you must need the option "Configuration".

If you do not need to divide the disk to partitions, for example, when it is a 60-gigabyte SSD, you can not create any partitions, and install Windows directly to the "unoccupied disk space".

But when there is a large amount of data on the hard disk, in this case, without special programs for working with disk space, it is not necessary. A section is required to install Windows, convert from logical to the main one.

5. ACRONIS DISK Director 12 program to solve the tasks

Appointed when creating a private or logic type subsequently change the standard Windows disk management utility is not possible. To do this, you will need to resort to more functional solutions in the form of third-party programs to work with the disk space of the computer, which will be able to conduct an operation without deleting the partition, with the preservation of its data. Against the background of competitors in terms of assignment by partitions of the discs of the main or logical type Acronis Disk Director 12, it is advantageous for the presence of "protection from the fool". Whereas, for example, Paragon Hard Disk Manager will thoughtlessly agree to the Windows technical section transformation experiment from the main in logical, Acronis Disk Director will carefully preize about all the negative consequences of the planned operation.

Acronis Disk Director 12 So smart program that even if this operation is confirmed, only the effect of the operation will occur, so to speak, deception for "especially persistent". This truly will not be changed, and after Windows restarting the technical section of the system will remain, as before, the main one.

For critical cases, when Windows is not loaded or simply not yet installed, Acronis Disk Director 12 in its interface provides for creating a bootable media.

After the welcoming window, select the "Windows-like representation" of the bootable media.

We skip the stage with the Linux kernel parameters.

Select the bootable media with UEFI support for computers based on this BIOS or limited to the usual version for 32-bit systems. The choice is basic only for Bios UEFI.

Finally, set up the boot priority from the selected media in the BIOS and run Acronis Disk Director 12.

6. Conversion of the main partition of the disk in logical and vice versa

In the Acronis Disk Director 12 window, be it a desktop window window, or this is an interface of the setting media, select the desired disk partition. You can choose at least in the disk partition table at the top, even in the visual representation at the bottom. Call on the section context menu. If this is the main partition, select the "convert to logical" function.

Confirm the decision.

Apply a waiting operation.

Once again, confirm the solution by pressing the "Continue" button.

The section is converted to logical.

Similarly, an operation for converting a logical disk section to the main one occurs. On the selected logical partition in the context menu, select the "Convert to Basic" function.

In some cases, return to the technical section of the main type Windows type in this way will be required to additionally restore the boot sector.

In conclusion

To complete this article would like to be a job for beginners that are going to experiment with the disk space of the computer. Check the potential of professional software in this area is not necessarily on the physical disk of the computer. For these purposes, Windows tools (in the same disk management utility) you can create a virtual VHD disk, initialize it and to carry out various kinds of experiments with it.

Excellent day!

If it is limited to some number, why can we assign all the letters C on z on the discs? If this is a special case, what is it?

7 Solutions Collect Form Web for "What is the maximum number of partitions that can be done on the hard disk?"

In the old division scheme, "MBR" you can have 4 primary sections or 3 primary partitions and one advanced partition containing any number of logical partitions. Although you can assign a disk letter for the partition, you can also map it as a folder in current versions of Windows, allowing more partitions or use subpower to connect to the number.

The EFI specification requires the GUID (GPT) table, supported by all modern operating systems, can contain maximum 128 sections on the hard disk of any size. GPT is also required to boot from hard disks with a volume of more than 2 TB. This partitioning scheme is now widely used with UEFI, supported by almost all new computers.

In addition to its own sections of Windows and Linux, there are also something called "logical volume manager", which can apply dozens, if not hundreds of virtual sections (logical volumes) over 4 (MBR) or 128 (GPT) of physical sections, Logical volumes can be assigned letters of disks or mount points in the same way as physical sections. They can also be bootable if certain limitations are performed.

It is also possible to have GPT formatting discs on non-UEFI systems and MBR discs in UEFI systems (with the exception of the boot disk).

On the disk using the traditional MBR format, the partition table has four slots. Each may contain a "primary" section, or can be used to create an "extended" partition, which may contain any number of subsections (frequently referred by "logical disks"). Advanced partitions are mainly bypassing for a small size of the MBR partition table, and there are restrictions on what they can be used. (For example, Windows bootloader must be in the main section.)

The newest GPT disk format supports much more sections - technically without restrictions, I think, but the operating systems impose a restriction on 128. These are all "primary" sections (for the use of MBR terminology).

From TechNet: View Storage Limitations: Local File Systems:

The number of disks that you can use for each server is limited only by the available memory for FAT16, FAT32, NTFS and UDF file systems.

So there is no hard limit on Windows by the number of drivers. The letter of the disc, of course, is limited, as they stop on Z. But the disks do not need to specify the letter of the disc - they can be mapped to the folder on another disk. From the same article TechNet:

Installed discs are useful if you want to add more storages into an existing volume without the need to expand volume. The installed disk is a local Tom connected to an empty folder on the NTFS volume. The hard disks do not cover the limit on 26 disks imposed by the letters of disks, so you can use mounted discs to access more than 26 drives on your computer. For more information about the mounted disks, including information about creating mounted disks on server clusters, see "Using NTFS-connected disks" in the Help and Support Center for Windows Server 2003.

Hard disks can be divided into four main partitions, or one of them can be configured as an extended section.

The extended section theoretically contains an infinite number of logical partitions, so, although in Windows only the letters of the disks to z: (plus some other characters), this is not a limitation of the number of partitions that you can create, even if you can "T assign it the letter of the disk .

If the disk is divided using GPT, the windows can process only 2 for the next reason. When GPT is used, each primary partition has another hidden partition that can be used with EFI. When Windows sees this EFI section, it is considered to be 1 main. Thus, 2 partitions in GPT - 4. This is a sad limit for Windows when testing a new assembly using the GPT scheme. Linux and OS X are much more flexible.

Maximum cuts allowed for MBR windows are equal to 4.

Directly called "section" means 4 parry. However, any of these 4 partitions, that is, one and only one of them can be extended further to "partitions" or logic discs. Thus, this is called 3 main particles and one "expandable" section. "Expandable" section as a logic disc can only work with letters from A to Z. Since alphabets A and B are used for floppy drives, only C-Z is available for use.

Theoretically in the disk can create an unlimited number of sections. The total number of sections is limited by the volume of space reserved to create partition entries.

GPT is a new standard that displaces the MBR. Which technology is better for the hard disk operation - this question is asked computer specialists and users of the PCs that set a new hard disk in the system. In fact, a new GPT came to replace the old technology and it would seem that the answer to the question "GPT or MBR is better?" Obvious. But you should notice the events. Not always "newly" in everything and immediately replaces "well polished old".

Prehistory.

We need a carrier for storing information. In computers for these purposes for several decades, and to this day, a hard disk is used. Operating systems (OS) are also recorded on this medium of information. In order for the PC to run the OS, first it will need to find the logical disk on which it is located.

The search is carried out using the Basic Input / Output System, abbreviated BIOS), the MBR helps it in this.

MBR - what is it

MBR (Master Boot Record) Translated into Russian "Home Download Recording" is the first sector (the first 512 bytes of the memory portion) of the media (be it a hard drive (HDD) or a solid-state drive (SSD)). MBR is intended for several functions:

Contains code and data (446 bytes - initial bootloader) that are required by BIOS, to start loading the OS.
Contains information about the hard disk sections (4 primary sections of 16 bytes each). This information is called Partition Table.
Guardians (0xaA55, size - 2 bytes).

OS boot process

Loading the operating system after enabling the computer - multistage process. Most PCs today prepare their hardware to work using the BIOS firmware. During the BIOS start, the system devices initialize the system devices, then searches for the loader in the MBR of the first storage device (HDD, SDD, DVD-R disk or USB drive) or on the first section of the device (therefore, in order to download from another drive, you need to).

Next, the BIOS transmits the loader control that reads the information from the partition table and is prepared to load the OS. Ends the process of our guardian - special 55h AH signature, which identifies the main boot record (OS load started). The signature is at the very end of the first sector, in which the MBR is located.

disadvantages

The MBR technology was first applied in the 80s in the first first versions of DOS. After time, the MBR was polished and running from all sides. It is considered simple and reliable. But with the growth of computing power, the need for large amounts of media memory has grown. Difficulties have arisen with this, since the MBR technology supports the work of only to 2.2 TB drives. Also, the MBR cannot support more than 4 major sections on one disk.

Features

GPT is located at the beginning of the hard disk, as well as the MBR, but not in the first, but in the second sector. The first sector is still reserved for MBR, which can also be in GPT disks. This is done in order to protect and in order to be compatible with the old OS. In general, the GPT structure is similar to the predecessor, with the exception of some features:

GPT does not limit its volume in one sector (512 bytes).
For the partition table in Windows, 16,384 bytes are redundant (if the sector in 512 bytes is used, 32 sectors are available by calculations).
GPT has a duplication function - the table of contents and partition table are recorded at the beginning and at the end of the disk.
The number of sections is not limited, but technically there is a limitation of 2,64 divisions due to the bit of the fields.
Theoretically GPT allows you to create disc partitions (with the size of the sector in 512 bytes; if the size of the sector is larger, then the size of the partition is greater) up to 9.4 zb (this is 9.4 × 10 21 bytes; to better seem to the size of the information media section It would have such a volume as 940 million discs of 10 TB each). This fact lowers the problem of limiting information carriers in 2.2 TB under the control of MBR.
GPT Allows you to assign a unique 128-bit identifier (GUID), names, attributes. By using Unicode Coding Standard, the sections can be named in any language and are grouped by folders.

Stages of OS download

OS loading occurs at all as in the BIOS. UEFI does not apply to boot Windows to the MBR code, even if it is. Instead, a special section is used on the hard drive, which is called "EFI System Partition". It contains the files that need to be run to download.

Boot files are stored in the directory / EFI /<ИМЯ ВЛАДЕЛЬЦА>/. This means that the UEFI has its own multizbar that allows you to quickly determine and load the necessary applications (in the BIOS MBR for this we needed third-party programs). The process of loading UEFI occurs as follows:

Enabling computer → Hardware checking.
UEFI firmware is loaded.
The firmware loads the boot manager, which determines which disks and partitions will be downloaded by UEFI applications.
The firmware launches the UEFI application with the FAT32 file system of the UEFISYS partition, as indicated in the boot record of the firmware load manager.

disadvantages

The shortcomings of the GPT are available, and the most tangible of them - there is no technology support in the preacheable devices using the BIOS firmware. OS Windows family can distinguish and work with GPT partition, but not everyone can boot from it. I will give a visual example in the table.

Operating system	Bigness	Reading, writing
Windows 10.	x32.	+	+
Windows 10.	x64.	+	+
Windows 8.	x32.	+	+

Also, among the deficiencies, GPT can be allocated:

It is not possible to assign the name of the entire disk as separate sections (there is only your GUID).
There is a binding partition to its number in the table (third-party OS loaders prefer to use the number instead of names and the GUID).
PRIMARY GPT HEADER and Secondary GPT Header) are strictly limited in the amount of 2 pieces and have fixed positions. In case of damage to the media and the presence of errors, this may not be enough to recover data.
These 2 copies of GPT (PRIMARY and Secondary GPT Header) interact with each other, but do not allow you to delete and overwrite the checksum in case it is not correct in one of the copies. This means that it does not provide protection from the GPT level.

The presence of such shortcomings shows that the technology is not perfect enough and still need to work on it.

Comparison of GPT and MBR partitions

Although the concepts of MBR and GPT are quite different from each other, I will try to compare them in general terms.

Also visually compare the OS load through the old and new technology.

Conclusion

Before deciding that it is better than GPT or MBR, put the following questions:

Will I use a disc with the section I need to store data or as a system for downloading Windows?
If as system, what Windows will I use?
Is there a BIOS or UEFI firmware on my computer?
The volume of my hard disk is less than 2 TB?

Having answered these questions after reading the article, you decide which technology is better at the moment it is for you.

P.S. Motherboards, which are printed now, are equipped with a UEFI firmware. If you have this, it is preferable to use the GPT style sections (but again, depending on what goals you are pursuing). Over time, BIOS will go back and sooner or later, but most computerized devices will work with drives using GPT.
