Here we can see, “Data Error: Cyclic Redundancy Check–We Have the Fix”

  • System errors are inconvenient to deal with because they cause the operating system to stop functioning properly. Finally, but certainly not least, they are usually lethal.
  • A cyclic redundancy check is a typical system issue that happens when Windows fails to recognize the devices connected to your computer.
  • Even if the changes don’t appear to be in your favor, there are a few things you can attempt if you’re stuck on this problem. First, check out the guide below to learn more about our solutions.

Follow the troubleshooting procedures in this article to resolve the ERROR CRC error code with the Data error (cyclic redundancy check) description.

ERROR_CRC: What it is and why it occurs?

When your system detects inadvertent modifications to raw data, it generates a cyclic redundancy check error code. For example, it’s commonly seen in digital networks and storage devices when Windows detects large disk modifications and fails to recognize the drives linked to your computer.

This issue can also occur in Outlook after the program has downloaded emails to your computer, blocking you from accessing your downloaded items. If your personal folder file is corrupted, you may experience this problem.

How to fix Data error Cyclic redundancy check

1) Check your disk for errors

You may use Command Prompt in Windows 10 to perform a disk check.

Start Command Prompt as administrator, type the command chkdsk C: /f, and press Enter. Replace C with the letter of the partition on your hard drive.

If you don’t use the /f parameter, chkdsk will display a notification saying the file needs to be fixed, but it won’t fix any issues. The chkdsk D: /f command discovers and fixes logical problems with your hard drive. Run the /r parameter as well to fix physical difficulties.

Go to Hard Drives in Windows 7, right-click the drive you want to inspect, and then select Properties > Tool. Next, check the ‘Automatically fix system file errors’ option under the ‘Error checking’ section.

2) Format your hard drive

If the previous approach fails, try formatting the issue drive. This problem should be resolved by formatting and restoring the default disk configuration. Remember that formatting your drive entails erasing all of the files and folders on it.

You can use Command Prompt to format your drive:

    1. Open the Start menu, type cmd, right-click the cmd search result and choose Run as administrator.
    2. Start formatting the C disk to exFAT by typing the format C: /FS:exFAT > Enter. Substitute the letter of the faulty drive for C:

You can also use the Disk Management program to format your drive:

    1. Select the Disk Management utility from the Start menu by typing disk management into the search box.
    2. Right-click the drive you wish to format and select Format. choose the Formatting option
    3. To modify the format process further, follow the on-screen directions > click OK on the warning popup.
    4. After the formatting process is complete, you can utilize your hard disk. But first, try installing the updates again to see if this activity fixed the problem.

3) Clean your temporary files and folders

Disk Cleanup is the simplest and quickest way to clear your temporary files and directories. Your computer acquires many unwanted files when you use it or visit the Internet.

These so-called junk files can slow down your computer and cause various errors, including the ERROR CRC error code. Clean your temporary files before attempting to utilize your drive once more.

    2. Right-click the affected drive > select Properties > select Change the letters and routes of the drivers.
    3. Click the Change button, then click OK to restore the old driver letter.

5) Install PartedMagic or Recuva

PartedMagic can also cure the Data error (cyclic redundancy check) error code, according to users. PartedMagic is a disk partitioning and data recovery utility that works with various file systems, including FAT16, FAT 32, HFS, and others.

You can try Recuva for free to see whether it works for you.

6) Use diskpart

The diskpart command can also be used to resolve the Data error (cyclic redundancy check) error code. Diskpart is a powerful tool for managing hard drives, but it might harm your computer if you use it incorrectly. So when using this command, use additional caution and remember that you’re doing so at your own risk.

    1. Start > type diskpart in the search box > right-click diskpart in the results list> Run the program as an administrator.
    2. To see all of the accessible devices, use the list disk command.

    4. To clean the drive, use the clean command.
    5. You’ll now use the create partition primary command to create a new partition.
    6. To pick the recently inserted partition, type the command select partition 1.
    7. Then type the commands activate and format FS=NTFS label=[add the letter your new disk] quickly to activate the new partition. Then, without the brackets, type the command.
    8. Type letter=Y in the assigned box (replace Y with the letter that you want to assign to the device).
