[SOLVED]: How to Fix Cyclic Redundancy Check Error (CRC Error)?

Summary: Cyclic Redundancy Check Error (CRC Error) can prevent you from accessing data on your hard disk and interfere with basic commands, such as copying and pasting the files. In this blog, we’ve explained the reasons that may lead to CRC Error and the ways to fix the error.

What is CRC Error (Cyclic Redundancy Check Error)?

Cyclic Redundancy Check (CRC) is a hash function that is used to detect errors or accidental changes to raw data in digital networks and storage devices. It serves as a data verification method and checks the accuracy of data on disk drives.

Cyclic Redundancy Check (CRC) Error indicates corruption of data. The CRC error occurs when there’s a bad spot on the media of your hard disk. The error message appears when a computer attempts to read data on a local drive, a network drive, an external hard drive, or any other media (CDs, DVDs, and Blu-ray), and corruption or suspicious change is detected on the storage device or the network. At times, CRC Error interferes with simple functions, such as copying and pasting the files in a folder.

When the CRC error occurs, you may see the following prompts:

  • F:\ is not accessible. Data error (cyclic redundancy check).
  • File _could not be accessed. Data error (cyclic redundancy check).
  • Cannot initialize disk. Data error (cyclic redundancy check).
  • Data error (cyclic redundancy check).
  • Error: Data error (cyclic redundancy check).

Note: In some cases, the system may prompt you to format the drive.

Reasons for Cyclic Redundancy Check Error

The CRC Error may occur due to the following reasons:

  • Corruption of the registry.
  • Abrupt interruption in the installation of programs.
  • Misconfiguration of system files.
  • File sending errors.
  • Corruption of data in the system registry.
  • Cluttering on the hard disk.
  • Development of bad sectors in the hard disk.
  • Bad network communications lead to packet errors.
  • Poor network wiring.
  • Faulty app or program installation.
  • Transmission losses.
  • Device accessing damaged data.

How to Fix CRC Error?

There are a few easy fixes that you can use to resolve CRC Errors.

  1. Simply restart the computer: This may fix a lot of problems, including the CRC Error.
  2. Reconnect the external drive: If the error appears while connecting an external storage device, remove the device and restart the computer. Attach the device again.
  3. Upgrade to the latest operating system: Updating the operating system (Windows or Mac OS) to the recent versions may fix a lot of data errors, including the CRC Error. It will also ensure the smooth functioning of the system.

Download the file again: If the error occurs while downloading a file or opening an email attachment, repeat the process of downloading. It’s possible that the CRC Error occurred because of a problem with the server or the network.

The above given are some quick fixes to resolve the issue. However, they may not always work. If these fixes do not work, follow the given methods to fix the CRC Error.

Method 1: Use CHKDSK Utility

To fix the CRC Error by using CHKDSK utility, follow these steps:

  • Right-click on the drive you want to check.
  • Click on ‘Properties’.
  • Select the ‘Check’ option. This should appear in the ‘Tools’ menu.
  • A dialog box will pop up. Select from the two options: ‘Automatically fix file system errors’ or ‘Scan for an attempted recovery of bad sectors’.
  • Click on ‘Start’ to begin the scan.
  • The scan will try to fix the CRC Errors.

This method may not work in two instances: If there are too many errors or the error is too large to fix. In such cases, the scan may get stuck or take too much time.

The system will prompt you with these messages:

  • You don’t need to scan this drive.
  • We have not found any errors on this drive.

In such a situation, use the Command Prompt to run the CHKDSK utility. Follow these steps to do so:

  • Avail Administrator rights of the system.
  • Go to the Start menu. Click ‘Run’.
  • Type ‘cmd’ and press ‘Enter’.
  • Type in the command ‘chkdsk /fx:’ where x is the letter of the drive you want to check. This is the basic scan.
  • You can also run an advanced scan. Type ‘chkdsk/r x:’ to do so. ‘X’ is the letter of the drive you want to check.
  • Wait for the scan to complete.
  • Restart the computer. Try to access the drive now.

NOTE: The advanced scan may take some time to complete.

Method 2: Run System File Checker

The system file checker finds the corrupted or damaged files and replaces them with new ones. This is useful for external storage devices, such as hard drives and SD cards. To run SFC Scan, follow these steps:

  • Connect the storage device to the system.
  • Go to the search option through the ‘Start’ menu.
  • Type run and click on the ‘Run’ app to open it. Type ‘cmd’ and press ‘Enter’. This will open the command prompt.
  • In the command prompt, type ‘sfc /scannow’. Press ‘Enter’.
  • This will start the scan.
  • Wait for the scan to complete.
  • Restart your computer and try to access the storage device.

CRC Error: How can Data Recovery Services help?

If none of the above-mentioned methods work, seek professional assistance. Perhaps, the hard disk or the storage device have developed a deep-rooted issue that the system checks cannot fix.

Stellar Data Recovery Services, in service for more than 26 years, can help in fixing complicated CRC errors. The team of experts at Stellar Data Recovery Services has decades of experience in successfully recovering data from corrupted or damaged storage devices, including those with CRC Error.

Stellar Data Recovery Services excels at recovering data in the following situations:

  • The hardware failure of storage devices.
  • Formatted SD cards and hard drives.
  • Accidental deletion of data from storage devices.
  • Physical damage to the storage device.

Conclusion

Cyclic Redundancy Check errors may occur due to corruption of a file or program registry, mistakes in setting configuration, or faulty app/program installation. If you get a CRC Error prompt, ensure that you stop using the device right away and focus on fixing the problem. You can follow the methods mentioned in this post to fix the issue. However, if these methods don’t work, seek the help of a professional data recovery services provider.
