A program for partitioning a hard disk into partitions. Download the disk partitioning program. Free AOMEI Partition Assistant
Reasons why it is necessary to divide into several sections HDD, everyone is different. For some, this is an opportunity to systematize necessary information and store it correctly; someone using several partitions uses several operating systems on their computer or laptop. Finally, if the hard drive is divided into several parts, then separately.
A little theory first
Think you know your hard drive? You might be surprised. ^^.
Partitions and hard drives, not even a fight
The hard drive is the hardware part of the computer. If you've disassembled your car, you can take it into your own hands.
A section can be seen as a clearly defined part of this hard drive. IN simple cases The hard drive has one partition and takes up all the space on the hard drive. But more difficult cases Multiple partitions can coexist on a hard drive. In this case, each takes up a portion of the disk space, and these different portions are sealed from each other.
Standard PC equipment: the simpler the better
This program is rightfully considered one of the best or even herself the best program For division of hard disk.
This is the most simple program, which will help you effectively manage multiple systems and different programs.
If the surface of the hard drive was observed with the naked eye, we could not see different sections: their separation is purely virtual. Partition information resides on a very small part of the hard drive called the partition table. This table contains the location of the partitions, their size, their names, etc.
A hard drive can only contain four primary partitions. This is quite common, but it is still possible to create benefits by using the extended section. Indeed, an extended partition is a special primary partition on which secondary partitions can be created. In the diagram below, the hard drive has three primary partitions and one extended partition, which itself has two secondary partitions.
Its main advantages are eliminating partition errors, converting file systems and protecting data. Another advantage is that this utility is very popular, because there are many reference information online.
2. Disk management in Windows
At any Windows versions there is a “Disk Management” function: this is the simplest, most accessible and sufficient effective remedy, which allows you to change partitions.
Each version of Windows OS has its own differences, but in the most popular ones (Windows Vista, Windows 7 and 8) there are no fundamental differences. Let's take a closer look at how to break a hard Windows disk using this utility.
What is the purpose of partitioning a hard drive?
There are three main sections in shades of blue. In a shade of red, there is an extended section divided into two secondary sections. The rule of four main partitions will be very important if you decide to partition your drive. Well, that's all great, but what's the point of finally partitioning the disk?
Installing multiple operating systems
Indeed, each section may contain another file system and therefore a different operating system. In the previous chapter, we discussed the problem of file fragmentation. When a disk is partitioned, each partition uses its own file system. Therefore, all "fragments" of the same file are in the same section. So when you want to defragment your drive, you need to defragment each partition one by one.
The program opens through the Start menu, and in the “Disk Management” item, even a novice user with the help of three main points (Expand, Shrink and Delete volume) does everything in real time necessary actions. Special knowledge this is not required - just give affirmative or negative answers and press necessary points menu.
Separate system and data
Another very common practice is to separate the system and data. It is necessary to distinguish between “software” and data. On the other hand, lost data is forever. So the idea is to isolate software and data by putting each into a partition.
The data will remain quietly in their section, unaware of the slightest change. This can also be useful when changing operating systems. If you want to go to this new version, nothing will force you to buy a new one full computer. The principle is always the same: your data will not be affected and you can continue to use it in your new system. What to do if your hard drive fails? What happens to grades?
There is only one drawback of the standard program - there are risks of failures that lead to the loss of certain sections. Risk exists when there is a disc or mass unnecessary programs, or when trying to partition the partition of the hard drive in which Windows is running: the processor does not always respond unambiguously to an attempt to “experiment” with the system partition.
As we have seen, partitions are virtual divisions on a single hard drive. If it breaks, all of its partitions will be lost. Therefore, where possible, it may be useful to separate the system and data by placing them on separate hard drives X. If the hard drive fails, second hard the disk has no effect. But that is not relevant to this chapter; here we are dealing with division.
To open it, for example, enter keyword"partition" in the search box in the Start menu and select the entry "Create and format hard drive entries." The window that opens is divided into two main parts. 
- At the top is a list of partitions of various disks connected to the computer.
- In this example there are three.
- Below is the distribution of partitions on physical hard drives.
- Here we have two hard drives: "Disk 0" and "Disk 1".
Free software for everyone
Two programs that can be downloaded absolutely free from the Internet - EaseUS Partition Master Home Edition and Paragon Partition Manager 11 Free - also easy to learn and use, but require certain knowledge.
1. EaseUS Partition Master Home Edition
The program helps not only to partition a hard drive, but also to create, copy, resize or completely delete partitions; and also restore deleted partitions.
Case Study: Single System and Data
This is all obviously just an example, you don't necessarily have to have the same configuration. Besides, now that we are sufficiently convinced of the theory, let's move on to practice! In the rest of this chapter we will describe a simple example hard partition disk.
First of all, defragment the disk that needs to be partitioned
Incorrect handling may result in data loss. Ask yourself if separation is really necessary. If you have any doubts, you can always ask for advice on the forums. Finally, if you don't want to partition the disk, you can read this chapter very well without doing any manipulation. Remember file fragmentation? We discussed this in the previous chapter. The principle is that files are stored on the hard drive in blocks that are not necessarily contiguous. The files are said to be fragmented.
The disadvantage that affects the popularity of the program is that it is only available in English. But knowing in English you can evaluate the excellent functionality and predictability of the program, stability of operation and the ability to carry out all procedures in virtual mode - at any time you can correct a settings error, cancel the disk partition procedure and restore the original data.
Disk management program
Here we will divide our disk into two partitions. This means that all fragments of the file must be on the same partition. To partition a disk without problems, it is very important to defragment it first. This way we limit the risk of having a file with fragments on the partition and other fragments in the second partition. This step is very important!
After a few minutes of calculations, the following dialog is displayed on disk. 
It may look complicated, but there's actually only one field available: the amount of space to reduce. Therefore, you need to enter the space you want to unlock on this partition.
2. Paragon Partition Manager 11 Free
The program again has an English-language interface, but for a beginner it is more interesting than the previous one - the main windows are quite clear and make it easier to navigate the functions. The disadvantages of the program include low speed work and unpredictability.
If funds allow, you can purchase a Russian-language version of this program for money, but it also retains the main disadvantages of the English-language product.
You cannot free more memory than the value specified in the available shrink space. If this value is low, it may be due to disk fragmentation. This is why defragmentation before partitioning is very important: it allows you to group all the fragments in one place and leave large space completely empty. But that's not true.
More detailed information on this issue you will find in this application. Then click the Minimize button to free up disk space. As you can read, the released space is marked as "Unallocated". To fix this you need to create this new section. Partition creation can only be done in "unallocated" space, which seems logical.
Programs for advanced users
These programs have advanced functionality - support for various disks and flash drives, the ability to convert file systems, create bootable media and much more. Fundamental differences are in speed, functionality and special features.
5. Active@ Partition Manager
The wizard will then open: Create Wizard simple volume. It's a lot like installing a new one. software. 
To get started, click Next to move to the next screen. 
Here we must specify the size of the new partition. The maximum available space is displayed. Click Next to move to the next screen. 
Things get a little boring on the next screen.
This program is free manager, making it easier to work with logical drives: A system reboot is not required when creating, formatting, or deleting disk partitions.
Even with accidental deletion The program will help you recover important partition data!
But the lack of the ability to change disk sizes (the partition must first be deleted and then another created in the same place) leaves no chance of recovering lost information.
The wizard offers to format the partition. Finally, you can provide a name for your new section. Again, you can put the name you want, this is just an indication. The last screen is a summary of the new section, so now is the time to check the information.
Removing or expanding partitions
Then you can see appearance our new section in the Start menu in the Computer menu. Therefore, there is a perfect seal between the system and the data. Be very careful in this part! Deleting a partition will result in the permanent loss of everything it contains! There is no cart issue here. As before, the first thing to do before starting is to defragment the disk. This allows you to place the order last and thereby limit the risks of errors during manipulations on partitions.
