Как исправить ошибку данных crc на жестком диске, в торренте или игре: освещаем в общих чертах

Ошибка в данных (CRC) возникает в случае несоответствии контрольных сумм файла к которому обращалась утилита. Это может означать, что файл был каким-то образом стал изменен или даже поврежденным.

В основном это проблема возникает тогда, когда вы устанавливаете приложения и игры; делаете копии файла расположенного на диске; пишите какой-либо диск или производите загрузку через торрент утилиту. Давайте теперь рассмотрим основные причины возникновения ошибки в данных crc.

CRC Errors: Data Error Cyclic Redundancy Check

Mostly, the Cyclic Redundancy Check error would occur in two situations:

1. Drive is not accessible, data error (cyclic redundancy check)

«My 1TB Seagate Free agent GoFlex has some error in opening the disk. First, it asked me to format the drive before being able to use it. I canceled that dialog as I have many files saved on it. An error message appeared, saying: ‘Drive is Not Accessible: Data Error (Cyclic Redundancy Check)’.»

2. Cannot initialize disk: cyclic redundancy check

«How can you fix an external HDD that fails to initialize? It gives ‘Virtual Disk Manager. Data error (cyclic redundancy check)’ each time I try to initialize the drive.»

So what is a cyclic redundancy check error?

The cyclic redundancy check, or CRC error, is an error-detecting technology commonly used in digital networks and storage devices to detect accidental changes to raw data. It serves as a data verification method to check the accuracy of data on hard disk drives, CDs, DVDs, etc.

When does the cyclic redundancy check error occur? When there’s a bad spot on the media of your hard disk, a CRC error may occur.

A cyclic redundancy check error can also be triggered by many other incidents that seem to be inevitable. For example, registry corruption, a cluttered hard disk, an unsuccessful program installation, or misconfigured files. Generally, when you receive the error message ‘data error (cyclic redundancy check)’, there is something wrong with the files or the hard drive.

What can be done to prevent a CRC error?

If you encounter a CRC error, it can be really annoying. Your go-to solutions such as rebooting the system won’t help solve a CRC error. You can’t temporarily disable the checking procedure either, which is why theaffected files seem lost at first. However, depending on the context, there are different strategies to solve the problem and save your files!

CRC error: here’s how to fix it when extracting files

If you want to extract compressed files, you can use the tools installed on your operating system. Many users do opt for third-party tools such as WinZip or WinRAR for packing and extracting documents, however, which often have a much greater range of functions. If you use this kind of software yourself, you should first check whether it is still up to date when your CRC error occurs. If you have updated the program and the error persists, try to reinstall it entirely. A change of program can also be the answer to your CRC problem.

Even an incomplete or incorrectly executed download can quickly lead to problems like a CRC error. If you have downloaded the corrupted file or archive from the Internet, we recommend that you download it again.

Many third-party tools can repair damaged archives or compressed files. If your program offers this option, you can try to fix the CRC error this way in the last step. For example, in WinRAR, you can start the repair as follows:

  1. Open the zipped file in WinRAR.
  2. Click on the “Tools” item in the upper menu bar.
  3. Select “Repair archive”.
  4. Specify a location for the archive to be repaired and specify the compression type (ZIP or RAR).
  5. Confirm to begin the repair.
  6. When the process is complete, there is a rebuilt variant of the archive in the defined target directory, which should not cause a CRC error during extraction.

Repair the faulty archive with WinRAR. This way, you’ll have a good chance of fixing a CRC error.

Extracting a file despite a CRC error (using WinRAR)

If a compressed file can no longer be extracted due to a CRC error, often most of the data is fine, and only a few files are corrupted. You could save the uncorrupted files even if you can’t fix the CRC error entirely. As an example, the following instructions show how this procedure works in WinRAR:

  1. Open the affected archive with WinRAR.
  2. Press the menu item “Extract to”.
  3. Mark the option “Keep broken files” in the “Miscellaneous” section.
  4. Confirm to finish this step.
  5. The files will then be extracted to the defined target directory — including the broken file(s). However, these files cannot be opened or edited.

After activating the option “Keep corrupted files”, WinRAR will unzip the damaged files without issue.

CRC errors during read or write processes — possible solutions

Because there is no specific troubleshooting for storage media errors, tools for general error checking of the affected media have the best chance of success. As with WinRAR, you can choose between third-party software (usually for a fee) and tools that are already integrated in your system. In Windows operating systems, the tool can be found under “error checking”. This comes preinstalled. It can be used in the following way for data problems, such as a CRC error:

  1. Open the File Explorer and select the problematic disk drive by right-clicking on it.
  2. Select the menu item “Properties”.
  3. Switch to the “Tools” tab.
  4. Click on the “Check” button under the “Error checking” options.
  5. Finally, press the “Scan Drive” button to start the error check.

Note that if you want to use the Windows tool “Error Checking” to fix CRC errors, you need administrator rights.

How to Solve the Data Error (Cyclic Redundancy Check) Issue?

1. Using CHKDSK Utility

To solve CRC error, you must repair the hard drive by running CHKDSK utility via command prompt. CHKDSK checks the integrity of your hard drive and fixes logical file system errors, bad sectors & file system metadata. You can run CHKDSK by following these steps:

  • Connect the storage device to your PC.
  • Press ‘Windows+Q’ and type CMD in the search bar.
  • Right-click on the ‘Command Prompt’ and select ‘Run as Administrator’.
  • A command prompt window appears. Type chkdsk X: /f where X is the hard drive or any other media storage device letter connected to your system. Alternatively, you can type chkdsk X: /F /X /R for the rigorous scanning and repairing.
  • Hit the ‘Enter’ button and wait until ‘chkdsk’ utility repairs the disk errors.

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

NOTE: If the problem persists, you need to format your storage drive. The format will erase all the data from the storage device. If you don’t want to lose data, you must follow the last solution given in this post, which is more effective and optimal.

2. Run SFC Scan

SFC stands for System File Checker, which is used to repair Windows system files including Windows DLL files, registry files, or other protected files. Sometimes due to corrupt file system or registry files, as discussed above, CRC error occurs.

The SFC scan finds 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 files size and volume. To run SFC scan, follow these steps:

  • Connect the storage drive
  • Click the Windows icon to open the search bar
  • Type cmd. Right-click on ‘Command Prompt’ and select ‘Run as Administrator’ from the options
  • Type sfc /scannow in the cmd window and hit the ‘Enter’ button to run the SFC scan

After SFC scan is finished, restart the system and try accessing the files from the storage media. If the problem still persists, please refer to the next solution.

3. Using a Data Recovery Tool

If none of the above listed solutions works for you, take the help of a powerful data recovery software like Stellar Data Recovery Professional for Windows.
