What Is Causing The CRC Error In The File And How To Fix It?


Sometimes your system may issue an error code that includes a crc error in the file. This problem can be caused by a variety of reasons.

Cyclic Redundancy Check (CRC) is an error detection code commonly used in digital networks and storage devices to detect accidental changes in raw data. During recovery, the calculation is repeated and if the control values ​​do not match, corrective action can be taken against data corruption.

A cyclic redundancy check or CRC error indicates bad hard disk space. The fact that you see this when you try to copy the file indicates that the wrong point may be in the file itself. We need to check, try to restore your file, and repair your hard drive.



When copying a file to a partition on the hard drive, a condition has already occurred if a similar dialog box appears.

The CRC error is one of those errors that prevent you from transmitting or accessing data. This error can also occur when a new application file is installed on your hard drive.

“No access to disk: data error (redundancy check error)”

An error message is displayed when trying to access an external drive. This could be due to a failed installation, registry corruption, or misconfigured files.

  1. To recover your data and save it for future use, here are two easy ways to fix CRC errors –
    Using the Windows Built-in Utility (CHKDSK)

    This built-in utility will help you fix minor damage or file errors to fix CRC errors when small. Follow the instructions to run CHKDSK. Right-click the drive you want to check> Click Properties> From the Tools menu, select Check. After that, a dialog box will appear in which you need to select parameters and start scanning.

    After scanning starts, wait until scanning is complete. Until then, CRC errors will be fixed. However, if it takes too long and gets stuck, you will have to look for another alternative, as the errors here seem large and irreparable. If no CRC error is found during this check, the dialog box appears again.

    This still gives you the flexibility to analyze your drive and check for errors. However, after scanning, it is wiser to choose another alternative.
  2. Service launch O CHKDSK utility from the command line – You can also run the CHKDSK utility from the command line if the previous CHKDSK test failed to resolve CRC errors.

    To run CHKDSK commands, the user must be a system administrator. Now use the following instructions:
    • Enter Command Prompt by typing “cmd” from the start menu.
    • Enter the “chkdsk / f x:” command at the command line. The letter “x” is a variable and you will need to enter the name (letter) of your drive to test it instead of x. This command is used for simple analysis and is useful for detecting very small errors.
    • For advanced scanning, enter “chkdsk / r x:” at the command line, where “x” is the drive letter. Fast scan is an early method, later scanning will take some time.
    • Now wait for the scan to complete. CHKDSK will generate a report and restart your computer.

The built-in Windows tool is often useful for fixing easily corrupted files. To troubleshoot damage problems and serious errors, beforeTry using external (third party) software, preferably with free trial support, to better understand the software.

Kernel for Windows Data Recovery is an effective tool for recovering lost data and completely recovering damaged files and errors. With this tool, you can recover data loss due to virus attack, unexpected shutdown, hard disk partition corruption and damage to Windows file system to its original form.

What Is CRC Error?

A CRC error informs you that the Cyclic Redundancy Check found corrupted or incomplete files. In this case, the corresponding data value and the appended CRC value do not match, resulting in an aborted action (save, copy, read access, etc.) and a corresponding CRC error message. Typically, this message looks like this:

  Data error (cyclic redundancy check)  

CRC error occurs frequently during extraction of compressed files and archives y. Cyclic redundancy check can also fail when reading and writing to local and external hard drives or USB drives, as well as CD, DVD, or Blu-ray.

How To Fix Cyclic Redundancy Check For Data Errors – 6 Fixes

Apart from the fact that we cannot copy files, access hard disk data, or initialize a hard disk, a data error detected by a cyclic redundancy check can ultimately result in a system crash on the computer or data loss on the hard drive. disk.

Therefore, it is necessary and urgent to correct a data error detected during a cyclic redundancy check. Here are 6 ways to remove Cyclic Redundancy Check Data error from your hard drive, USB stick, SD card, or other hard drive without losing data:

Method 1. Eliminating Data Error (cyclic Redundancy Check) With CHKDSK

The Windows CHKDSK utility can be used to find and repair errors or file corruption on disk that is causing the cyclic redundancy check to fail.

Steps to troubleshoot a cyclic redundancy check error using chkdsk:

Step 1. Open the “Command Prompt”:

Press Windows Key R, type cmd in the Run dialog box, and click OK.

Step 2. Type chkdsk E: / f at the command line and press Enter.

Replace “E:” with your hard drive letter to start scanning.

You can also type chkdsk E: / f / r / x to find and fix any errors found on your target device.

Step 3. Wait for the scan to complete and enter exit to close the window.

After checking and repairing your hard drive, restart your computer to see if it works.

Method 2: Eliminate The Cyclic Redundancy Check Error By Checking The Storage Medium

The Check Disk utility in Windows Explorer can also help you scan andfix any file system errors that are found that make a device with CRC errors unavailable.

Here are the steps to fix your reader’s CRC error:

Step 1. Open Windows Explorer, right-click an inaccessible hard drive or device and select Properties.

Step 2. On the Tools tab, under Error Checking, click the Check button.

Step 3. Select “Scan Disk” or “Repair Disk” if any errors are found.

After scanning is complete, restart your computer and see if you can reopen the device and reuse the saved data.

Method 3. Remove Data Error (CRC) With SFC – System File Checker

Windows system files typically contain hardware drivers, configuration files, Windows DDL files, and other files that make up the Windows registry. As mentioned above, registry corruption can lead to a data error (cyclic redundancy check) on your computer.

Thus, it is useful to run the System File Checker so thatRepair missing or corrupted system files on your computer to fix the loopback error caused by corrupted system files.

Step 1. Click Start and type cmd.

Step 2. Right-click on “Command Prompt” and select “Run as administrator”.

Step 3. If you are using Windows 10, enter the following command: First, create a Windows system image to protect your data:

Step 4. After the DISM command completes, enter the following command and press Enter:

After that, you can restart your computer and try to open the device again to use the data stored on it again.

Method 4. Data Recovery After Clearing CRC (cyclic Redundancy Check Error)

After using methods 1, 2, 3, the error in the cyclic redundancy check should be cleared by this time. You can reopen the storage device and use the saved data again.

However, if you find yourself in any of the following situations, you will need to execute indata recovery to get your files back:

  • The error message “Data error (cyclic redundancy check)” is always displayed.
  • You found that important data was cleared with errors.

Reliably recover data from inaccessible hard drive or recover files that were deleted using command lines



What causes a CRC error?

CRC errors can occur for several reasons. One of the most common causes of this error is a package error, which occurs when the network connection is bad or goes in and out. This creates a vulnerability for invalid data inserted into the file. Other possible causes are noise and poor wiring.

Where do CRC errors occur?

What is CRC error? CRC error is associated with inaccurate data transmission. Data transfer can occur from any digital medium such as a CD, floppy disk, flash drive, hard drive, or even a network package. CRC error is displayed when data cannot be copied from source to destination.

How do I fix a CRC error?

To fix the CRC error, you need to repair your hard drive by running the CHKDSK utility from the command line. CHKDSK checks the integrity of your hard drive and fixes logical file system errors, bad sectors and file system metadata.
