In this article, we will be discussing how to fix Cyclic Redundancy Check data error. It is basically a data verification method that is used by the computer to check the accuracy of data on the disks. CRC is used to detect accidental changes to raw data residing in the storage media.

What’s the Reason Behind This Error Message?

Redundancy Check Error

While copying files to the hard drive, you may receive an error message “Data error (cyclic redundancy check)”. This error message can occur due to hard drive corruption, misconfigured files, registry file corruption, cluttered disk, unsuccessful program installation, or when there’s a bad spot on the media. The CRC error is a critical issue that needs to be resolved as soon as possible to avoid system failure and, most importantly, data loss. 

Methods to Solve the Cyclic Redundancy Check Data Error?

There are certain methods available to solve the CRC (Cyclic Redundancy Check) errors.

Method #1: Using CHKDSK Utility

In order to solve CRC error, you must repair the hard disk by running CHKDSK utility via command prompt. This utility checks the integrity of the hard drive and fixes logical file system errors, bad sectors, and file system metadata. Users can run CHKDSK by following the given below steps:

  • Firstly, connect the storage device to the system.
  • Then, press Windows+Q and type CMD in the search bar.
  • After that, right-click on the Command Prompt and select Run as Administrator.
  • You will see a command prompt window. Type chkdsk X: /f where X is the hard drive or any other media storage device connected to the system. On the other hand, you can type chkdsk X: /F /X /R for the rigorous scanning and repairing.
  • Click the Enter button and wait until ‘chkdsk’ utility repairs the disk errors.

Once CHKDSK completes error checking, then you need to re-connect storage media to the system and then try to access it from File Explorer. If a user is able to access the data without any error, then they are required to immediately copy data from it to a safe location on the system. After doing so, format the hard drive or any other storage media via the Disk Management tool or DiskPart.

Method #2: Run SFC Scan

One of the techniques to resolve the Cyclic Redundancy Check data error is to run an SFC scan. It stands for System File Checker and is used to repair Windows system files including Windows DLL files, registry files, or other protected files. It can find the file issue and replaces the corrupt or damaged file with a new one. The entire process can take around 5 to 20 minutes depending upon the size and volume of the file. To run the SFC scan, follow the given below steps:

  • First of all, connect the storage device.
  • Then, click the Windows icon to open the search bar.
  • After that, type cmd and right-click on Command Prompt. Then, select Run as Administrator from the options.
  • Next, you have to type sfc /scannow in the cmd window and press the Enter button to run the SFC scan.

Once the SFC scan gets completed, restart the PC and try accessing the files from the storage media.

Method #3: Use a Third-party Tool

If the above manual methods do not work properly then you can make use of a third-party tool. One such tool is SysInfo’s Windows Data Recovery software, this utility provides an effective solution to fix all Windows data corruption errors. It recovers data from corrupt, damaged, or inaccessible hard drives within a few clicks. The utility facilitates multiple recovery modes depending on the File system i.e. FAT or NTFS. Thus, it is recommended to download the free demo version of this tool. Do you know why windows data recovery is neccesaty?


The above blog is describing the best possible solutions to fix Cyclic Redundancy Check data error. The solution includes the manual approach as well as the third-party tool. Now it’s up to you to select the right one for you.
