entranceCreate SSD sections. How to split the disk with the Windows installed system without data loss
The problem of improper formatting of SSD discs was discussed many times from the same time as these drives entered mass production. And although modern Windows operating systems have already learned how to work properly with solid-state discs, when formatting drives with third-party utilities (or in Windows XP), problems with the performance that will be described below are possible.
The reason for testing tests and writing the material was not only the desire to personally check the result, but also more the need to obtain specific figures, since too many Internet resources when describing the problem instead of the exact data change data provide blurred wording and refer to other articles, Which, in turn, refer to somewhere else. In the end, after several negative reviews were found on the impact of alignment of sections on SSD performance, it became clear that in the situation it is necessary to understand on their own. In the material are set out theoretical basis And the Guide to check the shift shift on SSD, as well as speed tests.
A bit of theory
Modern drives are represented by the operating system and programs in the form of memory, broken into the 512 bytes sector, however, at the physical level, the size of each disk sector is 8 times more and is 4 KB. To preserve compatibility with old applications over all of this, another interlayer is created, in which each sector is also 4 KB. Operational microsoft systems, issued before Windows Vista., reserve the first 63 sectors at the beginning of the MBR disk (Master Boot Record), and this leads to the fact that the logical (the topmost) and physical (lowest) strata of the drive shifted relative to each other, and therefore one logical sector is placed immediately on two physical. It follows from this that all I / O operations will be performed twice that not only reduces the performance of SSD, but also faster consumes its resource (as it is known, SSD has a limited number of recording cycles). As you can guess that the sectors on the physical and logical level coincide, the shift at the very beginning of the disk must be Katten 4 KB (4096 bytes).
How to find out whether the SSD section is shifted correctly
As mentioned above, modern systems Windows is able to properly shift the sections when formatting, however, if the initial breakdown was made in third-party utility Or in Windows XP, even reformatting in Windows 7 will not fix the situation. In this case, it will help either full removal Section (s) and the creation of a new one or the shift of the entire area of \u200b\u200bthe disk with the help of special utilities.
To find out if you need to do this in general, you need to run the MSINFO32 utility, go to the Components-\u003e Storage-\u003e Disks partition (components-\u003e storage devices), and find the partition starting offset for your SSD disk. 
If in the division of this value to 4096, it turns out not an integer, then the first section is shifted incorrectly. In our case, 32 256/4096 \u003d 7,875, which was expected after formatting a disk under Windows XP.
An alternative way to obtain the same information is the launch of the following command on the command line:
wMic Partition Get Blocksize, StartingoffSet, Name, Index
As can be seen, on the same drive (SSD in our case), the first section is shifted incorrectly, and on the second (HDD) is correct, since 1048576/4096 \u003d 256 (integer).
How to move the section
If nothing important is stored on the disk, then you can fix the error faster, removing all sections and creating them again from under Windows Vista / 7. Simple formatting here can not do, because the shift of the region does not occur.
If the disk is bootable and the operation described above is undesirable, then the section is shifted. Consider how it is done with free utility Gparted.
1
. Boot ISO-disk GParted (115 MB) or use one of the Linux distributions, in which Gparted may be available as a separate utility.
2
. Record the image on the CD or USB flash drive and load from the media.
3
. Select in the Gparted first section of the SSD drive and the Resize / Move command.
4
. Remove a tick near the round to Cylinders, we set "2" opposite the Free Space Preceding, press Resize / Move and then apply.
5
. We repeat the previous point, but instead of "2" in Free Space Preceding we put "1". Click Resize / Move and then apply.
6
. If there are several partitions on SSD, then operations 3-5 must be repeated with each of them, which may take several hours.
Gparted performs a shift operation without deleting data, however, when working with hard disks is always recommended to save important files on another media.
After rebooting, the system will most likely refuse to start, but the Windows performance can be quickly returned using the Repair Your Computer command in the first dialogue of any boot disk With Windows 7.
After the desktop appears, check the correctness of the alignment in MSINFO32: 
2 097 152/4096 \u003d 512 - The section shifted correctly.
Performance
Before you directly measure the speed, an attempt was made to calculate the input / output operations before and after formatting the disk. According to the Microsoft Help, the I / O Reads and I / O Writes settings in the Windows Task Manager show the number of relevant read or write operations for each specific process.
Five times before using Gparted and five times after it was made of copying the same ISO file with a volume of 700 MB on an SSD disk using file Manager Altap Salamander. In each case, the number of read and write operations was exactly 22.3 thousand. The lack of difference is likely to be explained by the fact that the Windows Task Manager works only with upper level Disc and does not know how to display the real number of operations at the base level.
For direct measurement of performance, HD TUNE and Crystal Disk Mark programs were used. The Kingston Hyperx SH100S3B / 240G SSD drive was first tested on a computer with SATA 2.0, and then on a platform with SATA 3.0 support, where he managed to fully disclose his potential: the speed of the drive is at the level of 500+ MB / s, but when using SATA 2.0 resumes In 200+ MB / c. All measurements were carried out 5 times, and the size of the test file in CrystalDiskmark was 1000 MB.
In the Benchmark mode, the HD Tune program was measured only to read the speed, since to test the record it was necessary to remove all partitions from the disk (for direct access to the utility to the drive), and this certainly deprived all the test sense.
SATA 2.0
It would be logical to assume that the drive, the performance of which is 2.5 times higher than throughput SATA 2.0, simply widespread in the ability of the interface and will not demonstrate any increase in the obsolete platform, but it turned out to be at all wrong. Growth, and rather substantial, was recorded even in such a configuration of the test system.
How clearly visible in the chart, reading speed in sATA mode 2.0 practically did not change, and the defining factor here (with the exception of the last two tests with a small block size) was the "bottle of neck" interface.
A completely different picture is consigned in tests for the recording speed, where in each case the obvious difference in speed was recorded. The minimum performance increase was 12%, and the maximum is 450%.
SATA 3.0
This mode allowed to reveal the entire potential of the drive, and it demonstrated in tests precisely those speeds that the manufacturer pointed out on the box (about 500 MB / C in read and write mode).
Check reading again did not bring special sensations, except HD Tune in the Benchmarks mode as it were corrected for the result in the previous test, where instead of a small increase in performance, a minor, but still a strange decline in indicators was recorded. The result of CrystalDiskmarkMark (4K QD32) is also allocated, where the difference in the speed was not a couple of MB, as in other tests, but much more.
The results of the record are also very similar to those obtained in SATA 2.0 mode. The increase in each test (except for the first and last) is almost identical, and it is easily explained by the fact that the performance of SSD in these tests did not depend on the version SATA interface. If you draw counts, the minimum increase was 18%, and the maximum - 310%.
Output
The test results were somewhat unexpected. First, in the theory, the speed of the drive was to increase and when reading, but the obvious improvement in tests was recorded only during recording operations. Secondly, prior to the start of the check, there were far more modest increases (if expected at all), but despite this, 3-4 multiple increase in recording speed were obtained in some tests.
Since the verification of the sections shift on SSD takes a literally less than a minute, we recommend all the owners of such drives just in case to check your solid-state disk and, in case of incorrect formatting, adjust it correctly to obtain maximum performance. Interestingly, the wrong shift is relevant for conventional drives, and there is information that the negative impact of this factor is manifested in R.A.i.d. Arrays. Consequently, the owners of such data storage systems, especially tuned to the maximum speed, and not to redundant security, it also makes sense to optimize its system.
Nowadays, when buying a computer, many people have a question: a PC with what drive is better to take, with HDD or SSD. To answer this question, you first need to understand what is the main difference between SSD from HDD. HDD hard drives appeared in the distant seventies and are used to this day in millions of computers. Main principle hard work HDD disk concludes in the record and reading on special magnetic plates of information. Recording reading is made using the head movement lever, and the magnetic disks themselves are rotated at very high speeds. Due to the mechanical component of the HDD hard disk and the recording and reading speed, it is inferior to SSD solid-state drives.
The principle of operation of the SSD solid-state drive Built on entries and reading information from special high-speed memory microcircuits included in its composition.. The same recording speed and reading information from SSD exceeds HDD several times. In addition, thanks to the microcircuit, the SSD is less susceptible to damage during blows and drops, and also has miniature form factors that allow it to be installed in the tablets and in ultrabooks. The main disadvantages Solid-state drives is price and Life Cycle. But progress does not stand still, so now it is clear how the price of SSD gradually falls, and the cycle of their overwriting increases. In this article, we will look at all aspects of working with a solid-state drive and we describe their characteristics, so if you decide to move from HDD hard disk on SSD, then this article will be very useful for you. In addition, we will consider such problems when the BIOS does not see SSD and many others.
What types of SSD discs exist and what better
When choosing a solid storage device First of all it follows pay attention to its form factor and different types InterfacesThrough which they connect to PCs. The most common form factor, as with tough disk HDD.is a 2.5 inches body factor forms. This solid-state drive can be found in many laptops and personal computers. Below is a list in which all types of form factors are listed, which are available in our time of solid-state drives:
- Type of 2.5 inches form factor;
- MSATA form factor type;
- Type of form factor M.2.
Below is a drawing with solid-state discs with a size of 2.5 inches, which is the most common and familiar to many users.
The above discs are quite popular models and have such labeling - Goodram CX200 240 GB, Kingston Hyperx Fury SHFS37A / 120G and SAMSUNG 850 EVO MZ-75E250B. Such discs are connected using a standard SATA interface that is used on most computers.
The second type of MSATA devices submitted below since 2009 is used mainly in portable computers.
Meet MSATA on desktop motherboards can be extremely rare, but in ultrabooks and tablets it is not uncommon.
The third form factor M.2 represents a new development that must replace the MSATA devices. Below is a picture, which shows the M.2 format disk of the company Samsung.
With solid-state disks, we figured out, now we will try to figure out the type of memory used in them. Now you can find devices with SLC, MLC and TLC types of NAND memory. The table below shows the characteristics of the memory relative to the NAND-chip.
| Nand-chip specifications | SLC. | MLC. | TLC |
|---|---|---|---|
| The number of bits in the cell | 1 | 2 | 3 |
| Number of cycles overwrite | 90000 - 100000 | 10000 | 3000 - 5000 |
| Chip reading time | 25 US. | 50 US. | ~ 75 US. |
| Programming time | 200 - 300 US | 600 - 900 US | ~ 900 - 1350 US |
| Erase time | 1.5 - 2 MS | 3 ms. | 4.5 MS. |
From the characteristics of the table, it can be seen that the discs built on SLC chips have 90,000 - 100,000 rewriting cycles. It follows from this that such discs will serve more time. But buying a SLC disk in our time is a very expensive pleasure, so most users prefer drives to MLC and TLC. So that our readers have an idea of \u200b\u200bthe life expectancy of a solid-state drive, we have prepared a table in which it is described.
| SSD SSD Resource on Memory TLC | ||
|---|---|---|
| Number of cycles overwrite | 3000 | 5000 |
| Memory size | 120GB | 120GB |
| Middle Screen Recording Day | 12GB | 12GB |
| 10X. | 10X. | |
| One cycle \u003d 10 * 12 | One cycle \u003d 10 * 12 | |
| SSD resource formula | SSD resource \u003d 3000/120 | SSD \u003d 5000/120 resource |
| Evaluation of life SSD disk | 8 years | 13, 5 years |
It is noticeable from the table that we took the cheapest drive with TLC memory chips. According to the formula, it is clear that our SSD passes one cycle of rewriting per day, and this is not so little. For example, a PC user can overwrite information less than 120 GB per day. But even with such not sparing conditions, this disk is able to work 8 or 13.5 years.
Below is a table for a drive with SLC, MLC memory chips.
| Payment | SSD resource drive on SLC memory | SSD resource drive on MLC memory | ||
|---|---|---|---|---|
| Number of cycles overwrite | 90000 | 100000 | 9000 | 10000 |
| Memory size | 120GB | 120 GB | 120 GB | 120 GB |
| Middle Screen Recording Day | 12GB | 12GB | 12GB | 12GB |
| Increased information recorded | 10X. | 10X. | 10X. | 10X. |
| Cycle formula overwrite a day | One cycle \u003d 10 * 12 | One cycle \u003d 10 * 12 | One cycle \u003d 10 * 12 | One cycle \u003d 10 * 12 |
| SSD resource formula | SSD resource \u003d 90000/120 | SSD \u003d 100000/120 resource | SSD resource \u003d 9000/120 | SSD resource \u003d 10,000/120 |
| Evaluation of life SSD disk | 750 years old | 833 years | 75 years old | 83 years |
Of course, the user can use more overwriting cycles per day, but then the table indicators will be different. For example, if you overwrite the SSD on MLC memory chips 10 times a day, then the life cycle of this disk will be 7.5 years. Judge yourself, with a 10-fold rewriting on this disk per day you need to overwrite 1200 GB of information, which is quite considerable amount.
Based on the information described above, the PC has enough SSD with the TLC memory chips.
Solve malfunctions, updating old SSD
In all new sSD disks Built in special subprogramme that removes garbage as it fills. This garbage removal mechanism is needed to save SDD speed. Solid-state discs exist on the market for a long time. In the old SSD versions in some models, there is no mechanism for protection against garbage treatment, as a result record speed on such disks noticeably falling. It is possible to solve this problem with a complete strengthening of information on the disk and subsequently reinstalling Windows. In order not to reinstall Windows, do not smash the new partitions on the disk, below we describe the method saving the previous state of the system.
First of all, you need to upload from the site http://clonezilla.org Clonezilla.which will help us to keep all sections. You can also use other means of cloning the system and its recovery. The process of creating an image of a system using Clonezilla. Neshes and it will cope with him like advanced userAnd the newcomer. After creating a complete backup, you can proceed to cleaning the disc. For this we need an image Linux Parted Magic. and utility UnetBootin.. You can download it on sites: https://partedmagic.com.and http://unetbootin.github.io. Using the utility UnetBootin. You can write our image on the flash drive by creating a boot drive from it. After creating boot flash drive You can boot from it.
Now on the desktop we find the program " Erase Disk."And launch it.
In the program window that opens, find the item " Internal Secure Erase."And click on it. After that, a window should open with the choice of your SSD. By selecting the required disk, the grip process will begin. After cleaning, restore the system with Clonezilla.. Restored Windows must function as if you have a new solid-state drive.
C. Linux Parted Magic. The user can break and create new sections on a solid-state drive. You can also split and create a partition on a solid-state disk as on HDD hard drive.
We solve problems with speed, BIOS and SSD firmware
The most common problem incorrect work, or when the computer does not see SDD, is an old version Microcoda BIOS. motherboard . You can update BIOS on any released motherboard. Most often, the problem with SSD is manifested with old versions of motherboards with the new UEFI BIOS. The BIOS update in most cases is made using the downloaded file with the microcode and the USB flash drive. The BIOS file is placed on the USB flash drive and use it to be updated. Each manufacturer of motherboards has detailed instructions On the BIOS update site.
Be careful when updating the BIOS, because the wrong update can spoil the motherboard.
Learn how bIOS version It is mounted on a PC from under Windows using the CPU-Z utility.
Many PC users buy SSD to significantly speed up Windows. But with such an upgrade, it should be borne in mind that most of the old PCs support only SATA-2 connector. When the solid-state disk is connected to SATA-2, the user will receive a limit on the data rate of 300 MB / s. It follows from this that before buying you need to know if your motherboard supports the SATA-3 connector, which provides bandwidth of 600 MB / s.
Still do work SSD. More stable, then you can get rid of most errors using the firmware. The SSD firmware is a microcode by analogy with BIOS, thanks to which the drive and functions. The firmware as well as BIOS can be found on the official website of the manufacturer SSD. The update instructions can also be found on the manufacturer's website. Such a firmware can solve the problem on some motherboards when SSD sees them.
The computer does not see SSD due to cable or drivers
In addition to the problems described above, very often the motherboard does not see SSD due to a problem cable or connector. In this case will help cable replacement SATA for serviceable. Also in many cases, the motherboard does not see due to the faulty SATA port, so you can solve this problem connect to another port.
If on a computer running on the HDD, connect SSD, then you can meet the situation when it does not see it. The system does not see the installed SSD due to old drivers. Can solve this problem by updatessuch Driverslike Intel Rapid Storage Technology Driver and AMD Ahci Driver.
SATA Ahci.
Mandatory mode for proper operation of the controller with your SSD is AHCI. This mode allows SATA control. Enable new features, including to increase the SSD speed. Unlike the old IDE mode aHCI mode Gives such advantages:
- Support for the AHCI hot switches to the Windows connected drives in Windows;
- AHCI allows you to increase productivity when using NCQ technology;
- AHCI mode allows you to use 600 MB / s (relevant for SSD drives).
- AHCI mode includes support for additional commands, such as Trim.
For windows installation On the modern motherboard it is not necessary to include in the settings AHCI mode, as it costs the default, but if it used more than old windows, for example, Windows XP, then switch the IDE mode to AHCI. Figure below shows bIOS settings MSI motherboard with AHCI mode enabled.
It is also worth noting if you installed Windows 7 after XP, then after switching to AHCI mode, the BIOS firmware sees the installed seven in IDE mode mode, and subsequently you will receive blue screen. In this case will help reinstalling Windows 7 in AHCI mode.
How to split SSD disk to sections
Many PC users have such a question in the forums: how to break the SSD disk to the sections. The answer to this question is quite simple - no fundamental difference when breaking the disks between SSD and HDD. Therefore, if you have experience breaking the HDD disks into partitions, you can also break the SDD. The only moment to be taken into account is the volume of SSD and HDD, it is significantly higher in the latter. For example, the volume of the system disk must correspond to the size installed on it, and free space for its proper functioning.
Summarize
After reading this material, each of our readers will be able to make sure that the advantage of modern solid State SSD. Over rigid HDD. Also in this material, our readers will find ways to solve problems related to SSD. It is also worth noting that solid-state drives You need to configure correctly in the operating system. For these purposes, we have an article "How to configure SSD under Windows 7, 8 and 10", which will help you properly configure the solid-state drive.
Video on the topic
When buying a computer or when installing Windows or other OS, many users want to break the rigid disk for two or more precisely, into several partitions (for example, a C disc into two disks). This procedure makes it possible to store separately. system files and personal data, i.e. Allows you to save your files in the case of a sudden "club" system and improve the speed of the OS by reducing the fragmentation of the system partition.
Update 2016: Added new ways to split disk (hard or SSD) for two or more, also added video how to split the disk in Windows without programs and in the Aomei program Partition Assistant.. Posted in management.
Smash the rigid disk can be several ways (see below). The instructions examined and described all these methods, their advantages and disadvantages are indicated.
- In Windows 10, Windows 8.1 and 7 - without using additional programs, standard means.
- During the installation of the OS (including, it will be considered how to do this when installing XP).
- Via free software Minitool Partition Wizard, Aomei Partition Assistant as well Acronis DISK. Director.
How to split the disk in Windows 10, 8.1 and Windows 7 without programs.
You can split hard disk or SSD in all recent versions Windows in the already installed system. The only condition is that free space on the disk is no less than you want to highlight under the second logical disk.
To do this, do the following steps (in this example, the system disk C) will be broken:
After these actions, your disk will be divided into two, and the newly created will receive its letter and will be formatted into the selected file system. You can close "Disk Management" Windows.
Note: It may turn out that later you want to increase the size of the system partition. However, this will not work in the same way due to some limitations of the considered system utility.
How to split the disk to the partitions on the command line.
Smash the hard disk or SSD into several partitions can not only be "Drive Management", but also with the help of command windows strings 10, 8 and Windows 7.
Be careful: The example shown later will work without problems only in cases where you have a single system partition (and possibly a pair of hidden) to be divided into two partitions - under the system and data. In some other situations ( disk MBR And already there are 4 partitions, with a decrease in the disk, "after which" is another disc) it can work unexpectedly if you are a beginner user.
The following steps are shown how to split the C disk into two parts on the command line.
Finish, now you can close command line: in windows Explorer You will see a newly created disk or, rather, a disc partition with the letter you specified.
How to split the disk to sections in the Minitool Partition Wizard Free program.
Minitool Partition Wizard Free is an excellent free program that allows you to manage partitions on disks, including one partition to two or more. One of the advantages of the program is that on the official website is available boot image ISO with her that can be used to create a loading flash drive (developers recommend doing it with using rufus) or to record the disk.
This makes it easy to perform actions to split the disk in cases where it is not possible to perform in the running system.
After downloading in the Partition Wizard, it will be enough for you to click on the disk to be divided, right-click and select the "Split" item (split). 
Further steps are simple: Configure partition dimensions, click OK, and then press the "Apply" button on the left at the top to apply the changes made.

How to split the disk during installation of Windows 10, 8 and Windows 7.
The advantages of this method include its simplicity and convenience. Breaking to the same takes relatively little time, and the process itself is very visual. The main disadvantage is to apply the method only when installing or reinstalling the operating system, which in itself is not very convenient, and there is also no possibility of editing sections and their size without hDD formatting (For example, in the case when the system partition ended, the user wants to add some space from another partition of the hard disk). In more detail, creating partitions on the disk when installing Windows 10 is described in the article.
If these shortcomings are not critical, consider the disk breaking process during the installation of the OS. This instruction Completely applicable when installing Windows 10, 8 and Windows 7.
Attention! When removing disk partitions, all the data will be deleted on them.
We divide the hard disk when installing Windows XP.
During the development of Windows XP was not created intuitively understandable graphic interface. But at least control and occurs through the console, divide the hard disk when installing Windows XP is also simple as when installing any other operating system.
Step 1. Delete existing sections.
You can redistribute the disk during the definition of the system partition. It is required to divide the section for two. Unfortunately, Windows XP does not allow this operation without formatting hard disk. Therefore, the sequence of actions is as follows:
Step 2. Create new sections.
Now you need to create the necessary partitions of the hard disk from the unintended area. It is done quite simple:
Step 3. Determine the file system format.
After the sections are created, select the section that must be systemically and press Enter. You will be prompted to select the file system format. Fat-format is more outdated. You will not have problems with compatibility, for example, Windows 9.x, however, due to the fact that the system of XP today is a rarity, this dignity does not play a special role. If also consider that NTFS is faster and reliable, allows you to work with files of any volume (FAT - up to 4GB), the choice is obvious. Choose the desired format and click ENTER.
Further, the installation will go in the standard mode - after formatting the partition, the installation of the system will begin. You will only be required to enter custom parameters at the end of the installation (computer name, date and time, time zone, etc.). As a rule, this is done in a convenient graphic mode, so it does not represent difficulties.
Free Aomei Partition Assistant program.
Aomei Partition Assistant is one of the best free programs to change the partition structure on the disk, the system transfer with the HDD on SSD and, including, can be divided into two or more disk. At the same time, the program interface in Russian, in contrast to another good similar product - Minitool Partition Wizard.
Despite the fact that the program declared support Windows 10, in this system, it did not break through for some reason, but also no failures occurred. In Windows 8.1 and Windows 7, it works without problems.
After starting Aomei Partition Assistant, in the main program window you will see connected hard drives and SSD, as well as sections on them. 
To split the disk, click on it with the right mouse button (in my case by C), and select the section "Section Section" menu.
In the next step, it will be necessary to specify the size of the partition being created - to make it possible by entering the number, or by moving the separator between the two disks. 
After you click OK, the program will be displayed that the disc is already divided. In fact, it is not so - to apply all the changes made, you must click the "Apply" button. After that, you can be warned that the computer will reboot to complete the execution of the operation. 
And after rebooting in your explorer, you can observe the result of separation of discs.
Other programs for creating sections on a hard disk.
To split a hard disk there is great amount Various software. It is like commercial products, for example, from Acronis or Paragon and distributing free license - PARTITION MAGIC, MINITOOL PARTITION WIZARD. Consider the division of the hard disk using one of them - Acronis Disk Director programs.
How to split a rigid disk in MacOS x full-time.
You can take a breakdown of a hard disk without reinstalling the operating system and without putting an additional software on your computer. In Windows Vista and above the disk utility is built into the system, there are also cases in Linux and MacOS.
To run a disk breakdown in Mac OS, do the following:
After that, after a short (in any case, for the SSD) section of the creation of the section, it will be created and accessible in Finder.
Why you need to share hDD In Windows? First of all, for the safety of your personal data. When the hard disk has only one partition, then all the files that are on this disk are: programs, documents, photos, files of the Windows itself - are stored in one place.
Now imagine that the system fails. All your personal files (photos, documents) with a lot of probability will be lost. Much more correctly, when the system files and user files are stored separately from each other.
Physically, they will still remain on a single hard disk, but will be on different sections. Sections can be several. One, as a rule, is discharged under the operating system and the program (system partition), another (or other) - under the user files.
One of the most simple and accessible ways is to divide the hard disk when installing Windows. How to do it, we are very detailed and on specific example Disassembled. What if the system is already installed and there are user files in it, how to divide the disk in such cases?
How to divide the disc with installed system Windows without data loss
Today we will analyze how to divide the hard drive into two or more sections with the already installed OS. And absolutely no matter what version of Windows you use. This method It will be relevant for any version, be it Windows 7 or Windows 10. In addition, if you already have two partitions, but you need to create a third method that are described below, and fit.
In fact, our task is reduced to "restart" from a large section (and in our case this is the only section - the system disk C) some part, allow 200 GB, and make a separate section from it.
You can do this in several ways, including using the Windows operating system itself, which has a special Disk Management tool. This method requires a minimum of effort and in most cases solves the task without third-party software. Let's start with him.
Before proceeding to the hard disk section of the installed windows system, you need to take some precautions. If there are important files in the system - copy them in advance for sighted media (flash drive, outdoor hard disk).
How to split a hard disk on two or more of the section? Method 1 - Windows systems
We use the Disk Management Tool. In Windows 10, it is enough to click the right key on the icon My computer, Select item Control - Disk management.
In others windows versions this tool You can find using the usual search or use a combination of hot keys Win + R., And enter the DiskMGMT.msc command.
We have a disk management window where the user's disk is displayed, which in this case has a size of 465.76 GB (disc 0). Almost all the HDD space is allocated to one section - C. C. Disk is also present (500 MB), which is reserved by the operating system at the stage of its installation.
In our case, 465 GB (the entire hard disk) for one system disk is not the allowable luxury, so the "outstand" from it is the maximum possible (how much system will allow the number of GB and make a new section from this free space.
As a rule, for the system disk, about 100-150 GB are removed. It all depends on specific user. 100 GB is enough if Windows and the most necessary software will be installed on the system disk. If in addition to the system and software it is planned to install modern games, then the size of 100 GB will be clearly not enough.
Before you perform any operation with a specific partition of a hard disk, do not forget to allocate it. It is enough to click on it with the left mouse button and the section will choose. Only then proceed to the operation.
Let's go to practice. Select the partition from which you want to "reset" the space. On the selected section, right-click and select the command. Say.
All sizes are indicated in megabytes, be careful. In a specific example, the maximum amount of MB that system "permits" to compress - 237.656 MB (232.09 GB). This means that after compression we will receive a disk with a size of 232 GB and a disc d - 238782 MB (233 GB). Not very optimal option. If he does not suit you, and it is required to "reset" more than the system offers, you will have to use third-party software, but this is later.
When all counts are completed, and the sizes of future partitions are set, click OK (or clicking ENTER). We have a new unrecognized section (200 GB). Do not rush to leave Disk Management. The disk separation procedure into two sections has not yet ended. We highlight a new section (200 GB), and click the right mouse button, select item Create a simple volume.
Run Master of creating a simple volume. In principle, everything is simple, just to follow the instructions of the master itself. Check out the screenshots. You need to set the future section of the letter (in my case it is D) and the file system - NFTS.
We look at what happened. We have one hard disk and divided it into two sections: a system disk with (265 GB) and a new Tom D (200 GB) for storing personal data. By the way, the new volume is now displayed in Windows Explorer.
Now you know how to split the hard drive for two or more windows tools. If this method suits you, and he coped with your task, then you can stop. However, if you are looking for a more optimal option, and, for example, you need to "pinch" a larger size than the system itself offers - we use third-party software. True, at first we need to return the original hard condition disk.
Delete the created section and return its system disk. Allocate New volume and click right-handed mouse clause Remove Tom.
We read warning and click OK. We get 200 GB that are not distributed.
Carefully check all the numbers and click Further.
We returned to K. initial stateWhen in the system one hard disk and it is almost completely reserved for one section (system).
