Computer file system. File system. What is it? Why is cluster size important?

Working on his computer, the user knows very well both the operating system installed on his computer and the file system that is used by it. If you happen to use someone else's computer and the system experiences any problems, the specific type of file system may be required.

Instructions

  • A file system is a way of organizing and storing data on various media, files, and hard drives. There are a large number of different file systems, of which the widest are: FAT16, FAT32, NTFS for operating systems of the Windows family; ext2 and ext3 for Unix systems and, for example, for the Linux operating system.
  • You can find out about the type of file system in different ways. The simplest one: open “My Computer”, select the disk you want to download, right-click on it with the mouse and select “Powerful” from the menu. The disk type and file system will be indicated in the window. For example, for Windows XP and Windows 7 the file system type will be NTFS.
  • If you have an unpretentious computer in front of you that you want to get excited about, you can view information about its drives using the additional Acronis Dick Director program. It starts right away from the CD, to select the drive from the disk, press after starting F12, you will be presented with a window to select the drive device. On some computers, the search window may use other keys.
  • Select CD selection and press Enter. Select Acronis Dick Director from the disk menu. Once clicked, a program window will open in which you will manage all the disks on your computer and separate them into designated file systems. The Acronis Dick Director program is a very manual utility that allows you to partition disks as required and format them according to the required file system. It also allows you, with a high level of reliability, to renew partitions of disks after their failure - you can renew disks from all folders and files.
  • The latest version of the Acronis Dick Director program, which runs under Windows, can also view all information about the file system. However, it is not recommended to carry out any operations on the disks in this version - after restarting the system, there is a great risk that the computer will be tempted to restart. If you need to break up the disk, try the version from the CD, it's more reliable.
  • Posted on September 8, 2012 Episode 2: How to find out the type of file system The file system of your hard drive contains a lot of computer parameters. For example, if you intend to access large files (more than a few gigabytes) from the Internet, your hard drive must work under NTFS controls. Also, the type of file system determines the speed of writing files to the hard drive and the speed of copying information from partition to partition.

    You will need

    • - PartitionMagic program;
    • - TuneUp Utilities 2011 program.

    Instructions

  • Using another method, you can find out about the type of file system regardless of your version of Windows. Open "My Computer". Use the right button to press the bears onto the hard drive partition. The context menu will appear. From this menu select “Power”. Next, look for the “File system” row. The file system type of this partition of the hard drive will be written.
  • You can also determine the type of file system using the additional program PartitionMagic. This program is suitable both for users of operating systems of the Windows family, and for computer users who have a Linux operating system installed. Find them on the Internet, download them and install them on your computer’s hard drive.
  • Launch PartitionMagic. Check until the computer scanning process is completed. At the main window of the program you will see a list of all available hard disk partitions. Once you have entered the “Vlastivost” section, you can look at the file system.
  • Also, to review the information, you can quickly use the computer monitoring and setup program TuneUp Utilities 2011. You can easily find it on the Internet. Although the program is commercial, it is a trivial term and a victorious one. Please feel free to install the program on your computer.
  • Launch TuneUp Utilities. Check out the current hour. When the program starts first, it begins to scan your computer. After scanning, you will be prompted to correct settings and optimize the system. It's an hour, you can wait a while. Or skip this procedure.
  • After this, you will find your way to the main menu of the program. Select the “Troubleshooting” section, and then in the next window - “Show system information”. In just a few seconds, the “System Informator” window will appear. In this window, select the “Disks” section. You can find information about the file system from him.
  • How to find out the type of file system - version for your friend

    The topic of the partition table for GPT and MBR disks became relevant after the proliferation of computers and laptops with Windows 10 and 8 installed. This instruction has two ways to find out whether the partition table is GPT or MBR on a disk. (HDD or SSD) - according to the operating system, and also during the installation of Windows on the computer (without installing the OS). All methods can be used in Windows 10, 8 and Windows 7.

    You may also find that there are problems with converting a disk from one partition table to another number of typical problems that are not supported by the exact configuration of the partition table: (and as a reminder), about troubleshooting when Windows is installed: , .

    For this method, you can either in Windows or press the keys Shift+F10 (on desktop laptops Shift+Fn+F10) while installing Windows from a disk or flash drive to open the command row.

    In the command line, enter in order:

    • diskpart
    • list disk
    • exit

    Revert the rest of the results of the list disk command. If there is an icon (star) there, then the disk has a GPT partition style, those disks that do not have such icons are MBR (usually MBR, so there may be other options, for example, the system cannot determine what kind of disk it is ).

    How to find out, MBR or GPT disk in Windows PowerShell

    Another way is to use Windows PowerShell and the command to retrieve information about storage devices (as an Administrator, it doesn’t matter) and enter the command:

    Get-Disk | ft -Auto

    As a result, in the table you see information about the disks of a computer or laptop, including the structure of sections in the remaining column:


    Indirect signs of the structure of partitions on disks

    Well, there are additional information signs that do not provide guarantees, but there are signs that allow you to recognize a GPT or MBR disk on your computer or laptop.

    In the event of an emergency power outage, the personal computer will crash. Fortunately, after the power supply has been updated, the computer can be turned on again and can be used properly. But in 5 hundred cases there is a problem. This is due to the fact that there are problems with the file system of the hard drive. Such delays lead to the fact that, when encrypted, it is not possible to read necessary files. And, obviously, the computer does not connect. To add changes to the file system, you need to check it for changes. And here comes the problem. Even checking the file system for corrections will require a computer. And there is no such thing as the legacy of this very mercy.

    Therefore, to verify this, you can quickly use a flash drive or a flash drive. Tobto. This will be a Live CD or similar to Live Flash. But in this case, if you have another computer at hand, you can build it easier. Using the “find it simpler” method, I quickly recovered. 1. by removing the hard drive from the file system 2. by connecting it to your computer as another storage device 3. by using the usual Windows methods, by checking the hard drive 4. by removing the hard drive after checking 5. by turning it to the right Ilya's computer. The launch showed that the effectiveness of the system has been updated. This is not a very complicated way of checking and updating the file system after it has errors.

    Verification of the file system using standard methods - step by step

    To verify the FS, the following operations are performed: - go to “Computer” or “My Computer” - depending on which version of the Windows operating system you have - open the context menu of the disk you want to verify - select the item in the context menu "AUTHORITY " - in the dialogue window that has opened, go to the "SERVICE" tab - on the tab that has opened, including the item "Check for the presence of errors" and the "Check" button - the button is displayed and pressed. - a dialog box appears that specifies the time to perform a disk scan - apparently firmly. (It is important to pay attention to those in the image where the “Check and update bad sectors” option is selected). In this case, if this option is selected, the verification of the warehouse takes place in 5 stages, and not in three. The verification will be more difficult, but one of the elements of the verification will be the search for and repair of bad blocks on the hard drive.


    If you are checking the system drive from which the Windows check program is running, please note that the check is currently not possible and it requires re-installation. If you get used to the re-engineering, the recheck will be done when your computer becomes compromised. In this case, if we check the file system on a hard drive obtained from a third-party computer and connect it until it is ready, the necessary logical drive will be checked immediately after startup. There is no need to re-enchant. Beginners may have a power issue - which is the most logical drive of the entire hard drive to check, which is the main logical drive? I advise you to check the one on which the operating system is installed. Everything is logical here. If the target computer is not ready to start the OS, the FS may be malfunctioning. If the OS is located on the original logical drive, then on the new one and there are problems with the FS. It's chaotic, that's all. After checking the FS for the presence of errors, a great chance has been removed that the computer will function normally again. If you didn’t see any success, then either the problems with the FS disk are fatal and you will have to reinstall the OS, or the reason for the computer’s failure lies in something completely different, and not in the hard drive.

    Starting a hard drive check for errors via the command line

    If you don’t want to run the disk scan using the OS graphical methods, you can run it using the command line. For this – launch – Start – Viconty – and in the command row window, write the command “cmd” – Viconti. If you have Windows 8.0 or Windows 8.1, then you will not know the “Viconty” window. The first command row window can be launched via Adding hot keys - "Windows + R".


    To start the verification, the command was entered - CHKDSK D: /F /R
    As you can see from the command to turn over, the “D” disk is set. Next commands: /F- command to correct pardons on disk /R- a command to search for bad sectors and update all information If you want to read in more detail all the capabilities of the "CHKDSK" disk check command, you can enter the parameters of this command through the Windows command line - for which vikorists we've got the team chkdsk /?

    Early in the morning, computer users come to grips with such concepts as a file system (FS). As a rule, the first familiarity with this term is obtained when formatting the information media: logical drives and media that are connected (flash drives, memory cards, external hard drive).

    Before formatting, the Windows operating system prompts you to select the type of file system on the device, cluster size, formatting method (Swedish or external). Let's figure out what a file system is and why it is needed?

    All information is recorded on the device, as it must be done in the correct order, otherwise the operating system and programs will not be able to process the data. This order is organized by the file system using new algorithms and rules for placing files on the device.

    If a program needs a file that is written to disk, it does not need to know how it is saved. All that programs need is to know the name of the file, its size and attributes to transfer the data to the file system to ensure access to the required file. The same applies when recording data on the device: the program transfers information about the file (name, size, attributes) to the file system, which preserves its own rules.

    For a better understanding, identify a librarian who shows a client a book by title. Or in the reverse order: the client gives the book to be read to the librarian, who places it for saving. The client does not at all need to know where and how the book is stored, without obliging him to serve the mortgage. The librarian knows the library cataloging rules and these rules are followed by the data that is posted back, then. changes its service functions. Which application has a library as valuable information, a librarian as a file system, a client as a program.

    Basic functions of the file system

    The main functions of the file system are:

    • placement and ordering of the data in the file view;
    • emphasis on maximizing the use of these information;
    • creation, reading and editing of files;
    • It is important to change the attributes of files (size, hour of creation and change, owner and creator of the file, accessible only for reading, accessing the file, timely file, archived, saved, maximum amount of file name, etc.);
    • designation of the file structure;
    • directory organization for logical file organization;
    • File protection during system failure;
    • Protect files from unauthorized access and change them instead.

    Information that is recorded on a hard drive or any other device is located in it based on a cluster organization. A cluster is a kind of small space of a small size that can accommodate the entire file or part of it.

    Since a file is the size of a cluster, it only occupies one cluster. Since the size of the file exceeds the size of the computer, it is located in a number of clustered computers. Moreover, separate clusters can be assigned to each other, but scattered across the physical surface of the disk. This system allows for the most efficient use of space for saving files. Setting up the file system - distribute the file at the time of writing to different clusters in the optimal order, as well as selecting the time for reading and viewing the program or operating system.

    See file systems

    During the evolution of computers, data storage and operating systems, a large number of file systems crashed and disappeared. In the process of such an evolutionary selection, today for work with hard drives and modern storage devices (flash drives, memory cards, external hard drives, CDs), the following types of file systems are mainly used:

    1. FAT32
    2. ISO9660

    The remaining two systems are designed for working with CDs. Ext3 and Ext4 file systems work with Linux-based operating systems. NFS Plus is a FS for OS X operating systems, like Apple computers.

    The greatest expansion has been achieved in the NTFS and FAT32 file systems, and this is surprising, because They are recognized for Windows operating systems, which operate on the majority of computers in the world.

    The FAT32 infection is actively hanging on more than the NTFS system through its greater reliability to save and protect data. Until then, the remaining versions of Windows OS simply will not allow you to install, since the hard drive partition will be formatted FAT32. The installer asks you to format the partition with NTFS.

    The NTFS file system supports disks with a capacity of hundreds of terabytes and a single file size of up to 16 terabytes.

    The FAT32 file system supports disks up to 8 terabytes and the size of one file up to 4 GB. Most often, qiu FS are used on flash drives and memory cards. FAT32 itself formats external storage devices at the factory.

    Proteus sharing a file size of 4GB today is already a big minus, because... Due to the extension of high-quality video, the file size of the film is too large and cannot be recorded on the device.

It’s so easy to take care of the health of your hard drive and make frequent calls to extend your life and create backup copies of valuable information.

    Verifying the disk using Windows

    Windows has a very handy method for checking your computer's hard drive, looking for new bad sectors and correcting file system errors. To start this verification, open the “My Computer” window, right-click on the drive you want to verify, and select the “Authority” item. Go to the “Service” tab and in the “Disk Verification” section, click the “Stop Converting...” button.


    To automatically correct problems detected during verification in files and folders, select the “Automatically correct system errors” item. Otherwise, the disk verification program will only notify you about the discovery of errors, but will not correct them.
    To perform a more thorough check of the disk, select the “Check and update bad sectors” option. In this case, the program will try to find out and correct physical problems on the hard drive.
    To achieve maximum results, it is recommended to enable the following options: “Automatically correct system errors” and “Check and update damaged sectors”. At this time, there will be a search for file and physical disk damage. All bad sectors (also called “bad”) sectors will be detected and marked as unusable for corruption, and the Disk Checker program will try to update the information recorded on them.

    To start the verification, press the "Start" button.
    The program will take a few steps, or after a year, we will check the hard drive. If you have files open on your drive or the operating system is currently running, you will need to restart your computer so that you will see the latest changes. When prompted to check the disk before the next computer reboot, press the “So” button.

    Close all programs and restart your computer. When the time comes, you will ask the robot to check the disk.

    Scanning your hard drive to check for defects and correcting them can take up to an hour. Therefore, be patient and do not turbo your computer until the operating system is affected.
    When converting a disk that does not have an open source file or running a program, there is no need to re-enable it. One mind - under the hour of verification with this disk it will not be possible to practice.
    The Disk Verification program uses an analogue - the chkdsk command. This is the actual disk check, but it is launched from the command line: click “Start” - “Viscont”, enter cmd (in English) and click “OK”.

    In the Windows command interpreter window, type in English chkdsk c: /r /f

    Press "Enter" on the keyboard.
    We decipher instead of the row you typed:
    chkdsk – disk check command.
    c: - the drive letter that is checked, it can be i d, i e, i f, etc. Dvokrapka pіlіteri disk ob'yazkovo!
    /r – the chkdsk command, launched with this parameter, detects bad sectors and updates that part of the data that can still be read from the disk.
    /f - the parameter indicates the correction of errors on the disk.
    If the /r and /f attributes are different on the disk that is being scanned, there may not be any hidden files, folders, running programs or an infected operating system. Otherwise, you will be asked to recheck the disk before the next computer reboot. Press the Y (English) key on the keyboard, and then Enter.

    Windows will notify you that the disk will be rechecked when the computer is turned on again. Now close the command interpreter window and restart your computer.

    When it comes time to use your PC, you will be careful about checking the disk on the blue aphid. As before, you have to check until you get involved with the operating system.
    Having detected file system defects, chkdsk will try to fix them, asking you for confirmation:
    Involved clusters: 5; Lansyuzhkov: 2.
    Re-do the treatment of cluster clusters in files?
    Press Y (English) on the keyboard. Windows will save your skin from rubbing at the root of the disk like the File0001.chk file. If you want Windows to fix problems on the disk without saving data from bad sectors, enter “N”.
    As chkdsk informs you about the large number of wasted sectors on your hard drive, it is important to save all important information from the hard drive to another device and think about repairing the drive or buying a new one.

    Reverting a disk in Acronis Disk Director Suite

    In addition to the features provided by Windows for rechecking the disk, this eliminates the need for unwanted programs. We recently learned about working with partitions in Acronis Disk Director Suite. This wonderful program can also check hard disk partitions for file system errors.
    To start the verification, see the required disk partition in the list and click the “Check” button.


    Select one of the verification options. It is recommended to select “Search for and correct detected defects”, but you can also try two other options: “Search for defects in sections” and “Search for defects and damaged sectors”. To start the verification, press the “OK” button.

    If you have selected “Search for defects and damaged sectors” or “Search for defects and damaged sectors” on the disk on which files, folders, programs or operating system are running, you will need to restart your computer in order to remove the data. One day ahead.

    Press Y (English) on the keyboard, and then Enter. Close the Acronis Disk Director Suite window first by clicking the “Close” button and restart your computer. When the PC starts to turn on, the disk verification process will start. The results of checking the disk partition will be displayed immediately.
    If the disk was verified without re-installation, the results of partition verification and corrections can be found in the Acronis Disk Director Suite window.


    However, it takes a lot of time to check the hard drive. It is much better to take constant care of the health and productivity of your hard drive with the help of the miraculous HDDlife program.

    Monitoring the health of your hard drive using the HDDlife program

    HDDlife is called upon to follow the hard drives of your computer and notify you of its demise. You can view the program and find more information about it on the official website http://www.hddlife.ru/.
    HDDlife has a sophisticated Russified interface and is simple to use. What’s even better is that the developers have created a version for laptops.

    After the first launch, HDDlife will analyze the health and productivity of all hard drives on the computer, and give you its verdict.


    In addition to the data about the health and productivity of the hard drive, you also receive information about the brand, the operating hour, the hard drive, the amount of free space, the operating temperature and the critical temperature of the hard drive.
    I have special respect for killing animals on the field of Visnovok. Here HDDlife will give you some helpful recommendations on how to save your data and prevent possible hard drive death.
    To view detailed information about the parameters that are checked when analyzing the health and productivity of a hard drive (SMART attributes), click on one of the critical instructions, developed under the health and productivity indicators.

    Finally, what has appeared, you will see all the attributes of the hard drive that are checked by HDDlife, and the status of each of them in the video display. See the parameter you want to click in the table and in the lower part of the window you will find your report description.

    Here you can set the attributes to be based on the hard drive model. Actions from them can be designated as "Invisible attribute". This means that the hard drive manufacturer has not published information about the name and purpose of this hard drive parameter.
    With special respect, look at the health attributes of your hard drive, shown in the table with special icons:

    • frequency of pardons;
    • hour of unwinding;
    • number of reclassified sectors;
    • positioning;
    • number of start repetitions.

    These are most often caused by damage, wear or malfunction of the disk mechanics. The smaller the numbers here, the worse for the hard drive. Having reached critical values ​​HDDlife will inform you about it. You will no longer have to copy all the important information from your hard drive, which is dying, to another device (flash drive, DVD, etc.) and seriously think about buying a new hard drive.
