    The Linux fsck (File System Checker) utility checks file systems for errors or unresolved problems. It should be a tool to resolve potential discrepancies and generate reports.

    This utility comes standard with Linux distributions. Generally, no safe steps or procedural setup is required to use fsck. As soon as someone downloads the terminal, you can’t wait to explore the possibilities of this tool.

    Follow this guide to learn how to properly use fsck checking in conjunction with file system repairon a Linux washing machine. The tutorial lists use cases and solutions for various use cases.

  • Linux or UNIX-like system
  • Access terminal beyond line
  • Command user with root privileges to run the tool successfully
  • When To Use Fsck On Linux

    How do I fix file system error in Ubuntu?

    Restore the correct file system Select the drive containing the entire file system in question from the list of storage devices on the left. If there is more than one award on the disk, select the number that contains the file system. On the current toolbar, under Volumes, simply click the menu button. Then click “Repair File System…”.

  • Use fsck to run a proper file system check as a preventive maintenance in case something goes wrong with your system.
  • A common problem that is easy to diagnose with fsck is load plan failure.
  • Another case: your company is getting an I/O error and your system files are currently corrupted.
  • You can also use the fsck resource to check the status of visible drives such as SD cards or USB drives.

    In the example above, filesystem can be device, partition, mt, period, etc. You can also use filesystem-specific options to useissue the at get rid of command.

    How To Check And Repair The File System

    There are some considerations to take into account before checking and therefore repairing a file system. You may need to find a disassembly device.

    Show Mounted Drives And Partitions

    To view only the devices connected to your system as the location to check the disk, use one of these linked to the tools available in Linux.

    One way to find the drive you want to scan is to list all drives in the file system using the df:


    df -h

    The tool prints usage data directly on your system and file systems. Note the drive that your organization should check with the fsck command.

    For example, to show parts of the first void, just use the following command:

    sudo parted /dev/sda 'print'

    How do I check file errors in Linux?

    The Linux fsck (File System Integrity Checker) utility checks file systems for errors and even pending problems. The tool is used to fix potential errors and get reports. This utility is notobviously comes with Linux distributions. There are no special steps or installation processes required to use fsck.

    sda is what Linux calls your first SCSI hard drive. If you have two, the secondMaybe sdb, incl.

    In our example, we got the effect because there was only one in the partition of this virtual machine. You will get better results if you have more sections.

    The drive name here is usually /dev/sda, in which case the number column shows the number from all partitions. In our case, it is correct: sda1.

    Unmount Drive

    Before running check disk, in addition to fsck, you must unmount the disk or partition. If you try to run fsck on a mounted drive or partition, you will get a serious warning:

    sudo unmount /dev/sdb

    Note that root filesystems can only be unmounted in one location. So today fsck cannot be used to start a single machine. More on this at the end of the guide.

    Run Fsck To Check For Errors

    Now that the client has unmounted the drive, you can do some fsck. To check the second drive, type:

    sudo fsck /dev/sdb

    The above example shows the entire output from a clean d sk. If you have multiple disk-related problems, almost all problems require action.

    How do I check my filesystem?

    Click the “Settings” button, then “Computer” or “My Computer” (depending on your operating system). In the computer window, click the drive you want to check, then click Properties from the menu. The Disk Properties window displays information next to the file system.

    The exit code of some fsck utilities returns a sum, most commonly associated with the following states:

    Mount Drive

    When you’re done scanning and restoring your device, mt . hard drive so you can use it again.

    Mount /dev/sdb

    Try With Fsck

    You can experiment with fsck before running the active check. Pass the specific -N option to the fsck command so they can run the test:

    sudo fsck -N /dev/sdb

    Automatically Fix Detected Errors With Fsck

    To try to solve potential problems without getting all the hints, pass the -y option, which fsck can do.

    sudo fsck -y /dev/sdb

    This is a way for people to say “yes, to try to fix almost all bugs” without being prompted each time.

    If no errors are found, the output looks the same as without the -y parameter.

    Skip Recovery, But Print An Fsck Error

    Use the full -n option if you want to check for potential errors in the logging system without fixing them.

    checking file system errors ubuntu

    We have our own second SDB disk which is logging a lot of errors. The -n flag prints any error without fixing it:

    sudo fsck -t /dev/sdb

    Force Fsck To Check The File System

    If you are running an fsck related to device cleanup, process the request to check the file system. If you want to force the use of the filesystem, use find, the -f.


    sudo fsck -f /dev/sdb

    A probable scan runs all five scans to check for corruption, even if it thinks there are “problems”.

    Run Fsck On All Filesystems Simultaneously

    If you want to scan all file systems at once with fsck, pass the -A a flag. This option runs our etc/fstab file onetemporarily.

    Because real filesystems cannot be unmounted on a well-functioning add machine, -R allows you to ignore them like this:

    Is there a chkdsk for Ubuntu?

    If your company is running Ubuntu Linux instead of Windows, chkdsk keep control will not work. The equivalent query for the Linux operating system is, of course, “fsck”. You can only run the following command on drives and filesystems that are unmounted (available for use).
