It's too early for a computer to perform such a procedure, like formatting a disk. When you want to start, the system needs power supply, which will set up a cluster expansion, which is often put in a deaf corner of the ears (and not only) of the PC.

How the computer collects data

In order to understand how to choose the optimal size of the disk cluster more quickly, it is necessary to look at the robot at a glance. If everything is forgiven, then you can figuratively show the memory of the hoarder at the sight of the stone, on the walls of which impersonal numbered small screens are stashed.

Also, there will be a directory (disk map) that is needed so that the system does not look at all the “screens”, but it knows, for example, that the file with the audio recording is in the screens with the numbers 45 to 62. when writing a file to memory, there were no empty screens, which should stand in a row, and the computer wrote the file at the screen, type 45 to 50 and type 65 to 77.

Apparently, it is displayed in the catalog, and if the system needs to get a file for work, it won't "marvel" at the disk map and "delete" the required record from the screenshots. The size of the cluster can be figuratively compared with the size of the box.

Here it is necessary to take into account the fact that a computer cannot put small pieces of various files into one screen, otherwise it will be a swindler in catalogue. Apparently, a file or some part of it can take up the entire screen, or it can be smaller. From the pointing butt, it is clear that only one screen is used - it is minimally possible to have a single memory, which is seen to save a small file, which is called “cluster expansion”.

Navigate to format

We are going to do this operation to clean up the disk again. Even though the space is occupied by anonymous files, then in case of extreme remoteness, the system will work according to your needs, but in certain situations you can get stuck in the whole procedure.

As well as vikonuvaty formatuvannya, it is not obov'yazkovo physically to see the data from the skin in the middle of the okremo - you can choose such a parameter, like "shvidka cleansing zmistu." In this way, it is not possible to erase the disk in full, only a record from the directory. The system will be given a command to accept the cluster as data, which, obviously, when writing a new file to a new file, the old data will simply be replaced by the new one. Tse vykoristovuyut deaky programs, scho vіdnovlyuyut vidalеnі files - while the cluster is not recorded yet new, it is still possible to win them together.

Another reason, if you need to change the power supply, what size of the cluster you need to choose when formatting, will be changing the file system.

Vіdminnostі mіzh rozmіtkami diskіv

To continue the analogy with the room filled with screens, it would be reasonable that there could be different ways to put data in order in them, as well as to systematize records in catalogue. The skin of such methods will be called a perfect file system, with its advantages and disadvantages.

How will you tamper with them, lie in the first line of the operating system and how it is planned to tamper with the computer itself, and what sort of files will be stored in your memory.

Here, it should be noted that the concept of the "cluster" is taken up to the rosettes created for the OS of the Windows family and those of the Macs of the Apple type.

FAT file system

This hard disk layout was used in DOS and early Windows operating systems, right up to the XP version. At the same time, under the understanding of the “cluster expansion”, the meaning of the minimum lot of the hard disk was nabulo, as it could be seen for the collection of data.

Clarification! Physically, the smallest parcel of the disk with data is a sector, with a volume of 512 bytes, such as in a cluster, stale in the file system of the OS, can be reduced from 1 to 128 pieces. Obviously, this value can be from 512 bytes up to 64 Kbytes.

FAT itself is used in three versions, which are reviewed by each other to record the cluster number in the catalog. Tse FAT 12, 16 and 32. It was understood that the number of “screenshots” could be given to those who had it, more of them could “increase” the OS of the computer.

Nedolіki that obezhennya FAT file systems

The reverse side of the medal is those that, if there are more screenshots, lower the system, then not everyone will be victorious, but only those who will stick out the numbers. Through this great hard drive, you may either not be formatted in this file system, or show a smaller amount after the operation.

Another minus is that if the cluster borrows a small number of sectors, then you can spend free space, even if you win 32 Kbytes, and from them you will take up less than 1 Kbyte, otherwise 31 will be left unoccupied.

The exchange, so that the minimum and maximum expansion of the cluster will be reached for the formatting hour:

*Through OS specifics.

** Some programs or OS that support FAT, theoretically, can read clusters over 32 KB. In such cases, the limit values ​​were 64 Kb and twice as much for the maximum volume of the disk. But if you spend time in such a situation, 50% and power reached, whichever cluster you choose, we’ll take it - it’s better to divide the disk into 2 parts and to beat the “screen” with a total of no more than 32 Kb.

NTFS file system

Created to replace the old versions of FAT to support disks of great technologies and new technologies that are implemented in operating systems. In front of us, we can see a possible number of clusters, the number of which can reach 248. This allows NTFS to be copied on disks with a volume of 16 Exabytes (16 million Terabytes), and the size of the files that are copied is limited only by the capacity of the carrier.

If the cluster expansion when formatted with NTFS partitions can be approximately, as well as in front - from 512 Bytes to 64 Kbytes, then the file system's capacity for security is an order of magnitude higher. Її records can be assigned access rights to a number of computer masters, є the ability to assign quotas of available disk space, as well as the files themselves are protected in case of failures, for example, when electricity is turned on.

Since the file system is far from depleting its resources, then it is necessary to see what kind of cluster expansion it is necessary to install again on your application.

What does the size of the cluster add to - like a legacy

The biggest problem you can create is too much disk space, which is not viable. But only in that case, as there are a lot of small files on the disk. For accuracy, it is necessary to indicate that it is accumulating a total of 1 TB, it will be necessary to use different files - video, audio and text documents, and leather from files to borrow a cluster vikoristovuєtsya).

For locking the cluster expansion for formatting, 4 KB are installed. If there are 100,000 text documents on the disk, 100 bytes each, you will spend 460 megabytes.

Important! It is necessary to remember that the greater the size of the cluster, the less pressure on the hard drive.

It can be seen from the table that it is not planned to save a large number of other files on the disk, so that the destinations for music and films, then it is better to set the maximum size of the cluster. Otherwise, it is necessary to choose among the bajans to spare hundreds of megabytes and potentially more avenues for carrying, and also to think about how to collect on a new 100 thousand other files.

I’ll respect the next step on the system partition of the disk, on which the system is installed. If, when installed, it is formatted by third-party programs that allow you to choose the size of the cluster, then you can’t guess what only in the Windows folder is close to 90 thousand. files, and more close to 50 thousand. - in papacy koristuvacha ... It’s better for him to deprive the golden mean, proponated by the system.

Which cluster rozmіr choose pіd hour formatuvannya - I can't name

I am familiar with my readers and today it is acceptable for me to move from theory closer to practice. Today we know, what kind of cluster expansion to choose when formatting NTFS. The NTFS itself often stands at the expense of the majority of coristuvachs, to which it is pushed. It's really not necessary to blame the hard disk for an hour before reinstalling Windows. And also in other situations.

On the other hand, we can guess what kind of cluster and NTFS and what kind of connection between these concepts. Also, computer memory (both flash drives, or memory cards) is divided into different sectors with a volume of 512 bytes or 4 Kb, which are grouped into clusters. Obviously, the cluster expansion is a multiple of the sector obligation.

And I would like to thank you very much for your computer intuition, as it will help you choose the optimal size of the cluster. On whom I will finish and say goodbye to you.

Up to quick insights in new topics of my blog.

In the process of formatting a hard drive, a flash drive or an SD card, it is prompted to select the cluster size when formatting and immediately select the required type of file system. Cluster expansion can be recognized using the standard Windows defragmenter.

The destination cluster is respected by the minimum amount of memory required for one document. The memory is divided into middle parts, in which we will then distribute the data. An important step is to determine the size of the sector, the most important number of files to write to the file. For example, the size of the middle is 4096 bytes, and the file that is being recorded should be 300 bytes. At this time, the file will borrow a sector again. The file is 4000 bytes long and covers the entire sector.

Sector commitment

The standard size of the cluster is stored in the selected file system:

• FAT32 varies from 1024 bytes up to 32 kb;
• NTFS cluster size (NTFS) from 512 b to 64 kb;
• FAT should be set to 64 kb and it won't be popular among the hardliners;
• exFAT with the size of the cluster is available in 512 bytes up to 32 MB.

For the correct designation of the city, the middle of the next order is designated, as the data are taken on the nose, which type and obsag. For photographs, videos or music, it is better to choose the maximum volume in the middle. If the disc is to be featured for documents, it is recommended to record your choice on a small contract.

If you want to sum up, what size of the cluster you choose for the hour of formatting, it is recommended to leave the back of the promotional value for the promotion.

On the swidk_st of the robotic wearer, the expansion of the cluster is poured in front of us. The less obsyag, the more operations are performed by the system, and the less security of the record or the data. In other words, the speed of the robot determines the size of the sector: whichever is larger, which is more practical.

The formatting of the disk troch is removed from the flash drive. If you format data on a flash drive, then the system will be more likely to be deleted in the middle.

Poshkodzhennya and renewal of clusters

Through the voltage drop, or the factory gateway, bad sectors of the hard drive are sent, at that time it is recommended to check the HDD for the presence of low-frequency cores, and in case of different manifestations - to renew it.

To restore broken sectors, you can tweak the Victoria program, HDDRegenerator or the standard Scandisk utility. Cluster updates:

1. V_dkrivaєmo "My computer".
2. At the menu of the required disk, select "Power".
3. It is known that he distributed “Service” and embossed “Vikonati perevіrka”.
4. At the vіknі, scho it appeared, we choose “Change and confirm”, after which we press “Start”.

Prevention and sight

Zrіdka, conducting similar procedures, you can succinctly suggest the term robotic information carrying:

• follow the disk space, see non-essential files manually or for additional special programs;
• detect at the early stages of the pardon, by hourly testing the disk with system utilities;
• break the winchester into sprats;
• don't forget to backup important files.

Unique mechanical abilities and hour after hour, do not forget about defragmentation.

Koristuvachs of any operating systems at least once stuck with such concepts, like a cluster. This word means a single value, according to which one understands the analysis of the middle of saving files. Call the rozmіr to lie down in obedience to the memory of the wearer.

you need

• Windows OS.

Instruction

When formatting a disk or a flash drive, you sing-songly noted that the system was telling you to choose the size of the so-called cluster. The rozmіr varies depending on the type of file system. For example, for NTFS, the minimum size of the cluster is 512 bytes, and the maximum is 64 KB. For FAT32 - type 4 to 64 Kb. Most of all, there are a lot of options, so you can put an unprepared koristuvach in front of logical nutrition: what kind of cluster expansion to choose when formatting a flash drive, disk, or whether there is any other accumulator?

What is cluster expansion

cluster, eng.) - the whole block in which the system records information on your storage device. The entire disk (flash drive) is made up of a great array of blocks, skins to avenge the number of given ones. Cluster expansion does not affect the volume of the disk, but it can be connected to those, as the system works with the files on your media, that is how much space is effectively accessible to it.

Select the cluster expansion

It is unlikely that you will notice with an indefinite glance the difference in case of different cluster expansions, but this parameter affects the productivity of the file system. When choosing the size of a cluster, lay everything down for the sake of which you will be victorious. If you save a lot of other files, then change the size of the cluster as soon as possible, so that the system does not waste space in the distance. If the disk is stored in the largest of the largest files, then you can increase the size of the cluster, which will increase productivity, Windows windows will spend less time before the middle.

It’s better to understand it better to help a simple butt:

If you have a file with a size of 3 Kb, and a cluster size of more than 4 Kb, then the file is borrowed the whole cluster or middle. Tse means that 1 Kb free space will be wasted. It is not possible to write other files at the expense of the space, so the space is actually spent for nothing. On 10 such files, the loss is already 10 Kb, on 100 - 100 Kb, on 1000 - 1000 Kb just. In such a case, it is more convenient to use a cluster size of 512 bytes or 1 Kb, a single file will take six or three clusters without fragmentation, and the middle of the disk will not be shared. In this way, the efficiency of collecting information is increased, but if the productivity changes, the chips of the system need to be more effective before blocking.

In the world of growing accumulating daedals, more daedals are melting, at the same time, daedals play a lesser and lesser role from the cluster. Vykhodyachi z tsgogo, universal solutions vikoristovuvat parameters of the cluster size for locking and do not change them. Obviously, as a scrupulous coristuvach, if you want to work everything as required and in ceramics, then you should look out for the fact that for large files there is a large cluster expansion, and for small ones - a small one. But again, you don’t remember especially the difference, because you just don’t save tens and hundreds of thousands of files in the volume of 2-3 Kb on your flash drives or hard disks.

How to recognize a disk cluster or a flash drive

A simple command, vikonan in the command line, to allow you to recognize, what kind of cluster expansion is victorious on a disk connected to the computer. Note: For vykonanny tsієї command you need oblіkovy record with the rights of the administrator. If your profile does not have any rights, the system will ask you to enter the Administrator's password.

Now you know what you need to expand the cluster and how to proceed when formatting a disk or a flash drive.
