CRC data error how to fix. How to treat the crc error and how to fix it in the data. How to fix CRC error - alternative options

When installing programs or games, it gives the error “ Error in CRC data file cannot be copied". The same thing happens when copying some files from a disk or flash drive to a computer.

Most often, this error occurs for one of three reasons:

1. The file you are trying to open or copy is damaged.
2. Damaged media, flash drive, portable external hard disk, etc.
3. The computer's RAM is damaged.

File damaged

If you downloaded from a torrent, then delete the files related to this distribution and the torrent file. Then download again and try to launch again. If the error repeats, then there may be a problem with the distribution and you need to find another distributor and download a new torrent file.

If you download from a flash drive or external hard disk and you receive this error, most likely the file needs to be copied to the media again, since it will no longer be possible to restore it.

Damaged media, flash drive or external hard drive

Right-click on it -> Properties -> Tools -> Check for errors. If you're lucky, you'll be able to fix the errors in automatic mode, after which everything will work fine. If the check does not help, then the file cannot be restored, and the media will have to be changed.

Checking RAM

To check your RAM, download the MemTest program or an equivalent. It will help confirm the memory problem and then you will need to replace this module with RAM. You can find the MemTest program or an analogue in Google or Yandex in a couple of minutes by searching for “RAM diagnostics”.

portable storage media, solid state drives, flash drives and hard disks– devices for transferring and storing files. But sometimes, when using one of these drives, a "Data Error (CRC)" warning appears. This warning appears when you try to copy data between these disk devices or when installing applications and games.

For example, an error may appear if the external HDD or the flash drive for some reason turns off while copying files.

A cyclic redundancy code (CRC) usually indicates a hardware problem, but can also be related to software. An error in the CRC data may indicate a breakdown HDD or appearance bad sectors on its surface. In solid state SSDs with interface PCI Express, sometimes due to the presence of a layer of dust on the device board. The error also occurs when there is poor contact in the SD card connection adapter, due to a problem USB port, and this can be easily verified. On the software side, CRC indicates disk driver failures.

Before treating it with special utilities, there are several ways to narrow down the source of the problem.

1. If the error occurs with an external hard drive or flash drive, try a different port. The port may be faulty.
2. Try copying the data to another drive. If an error still occurs, check on another computer.
3. If you cannot transfer to other storage media, the problem may be with the file. Most likely, a broken sector has formed where it was recorded. If there is no access to it and it is important, we restore bad sectors MHDD program or Victoria, and safely transfer it to another medium.
4. The game installation file downloaded via a torrent client does not launch? Most likely, a damaged archive was downloaded. Delete it and download a new one from other torrent sites.

Drive letter not displayed

One solution is to check disk drives for errors. file system Chkdsk utility. Testing requires a drive letter, but what to do if it is not displayed in Explorer. There are several solutions.

Connect the undetectable hard drive to another computer as a second one.

Press the Win+E key combination and see if the drive shows up in Explorer.

If not, press Win+R to open the Run window. Enter the command devmgmt.msc and confirm the launch with Enter.

Expand the “Disk Devices” tab and check if the problematic disk is listed. If it is missing, right-click and select “Update hardware configuration” from the menu.

If a yellow triangle appears in Device Manager with exclamation point, this means there is a problem with the drivers. Right click on unknown device and select Update Driver, then Automatic Search.

If this does not solve the problem, right-click and select Uninstall and restart your computer, or check for an updated version of the driver on the official website and update it manually.

Now press Win+R and type diskmgmt.msc. You should see a disk with a status of "Unallocated" marked in black. Right-click and select Initialize Disk.

Open Windows search, type “command prompt” and at the found position in the search results, right-click and select “Run as administrator”.

Type diskpart and confirm with Enter.

Then type automount enable and confirm with Enter.

After rebooting the system, the letter should appear.

Chkdsk disk check

It's built in Windows tool to identify file system errors and bad sectors and fix them.

If you receive a CRC error message when copying from a USB drive, check that external drive first. There's no point in spending hours testing your hard drive only to find out that the problem is in a flash drive that only takes a few minutes to test.

Run Command Prompt as an administrator. Type the command chkdsk X: / f, where instead of X, enter the letter of your erroneous storage medium. Check the letter in Explorer by pressing Win+E together.

Once completed, the test results will appear.

If the CRC error persists, try running chkdsk before booting Windows.

1. Connect bootable USB flash drive with a recovery disk or Windows installation disk to your computer and reboot the system.
2. On the first screen with the manufacturer's logo, press one of the Esc, F8, F12 or F10 keys, which is intended to enter the Bios.
3. After entering the BIOS, look for the Boot options or similar section to change the boot priority.
4. To change the boot order, use the arrows to move to first place USB drive(or CD/DVD depending on what you are using).
5. Save the changes and restart your PC.
6. When booting from installation disk specify your keyboard layout and language. On the Install Windows page, click the System Restore link.
7. Go to "Troubleshooting - Advanced Options" and find the "Command Prompt" item.
8. After logging into the command interface, enter chkdsk X: /f.

After testing is complete, check if this solution helped fix the error.

System utility for disk diagnostics

Windows comes standard with a Check Disk utility that is easier to use than the Chkdsk command.

Note: If you selected "C", the computer will ask you to schedule a scan. This means that the system storage will be checked the next time the system boots. Click "Schedule a disk check."

Wait for the scan to complete. As mentioned, this may take more than a couple of hours.

Quick formatting

We use this method as a last resort if the CRC error could not be corrected using the chkdsk utility. If there is important data on the disk, then this method will help restore it.

When quick formatting is recorded boot sector and an empty file system table. At the same time, the files are not erased unless you copy something new to them that will replace the old data.

After quick formatting, you need to use a data recovery utility.

Connect the drive to your computer. If problems arise, install it on another PC as a second hard drive.

Use the Win+E keys to open the Explorer window. Select the failed device, right-click and select Format.

Check the “Quick” option and confirm execution on Start.

Once the format is completed, launch the data recovery application. We recommend using the Recuva program, free version which is capable of recovering all data.

To fix cyclic redundancy check error, you may have to resolve hardware issues such as bad sectors on your hard drive. Often, removing debris from external media such as CDs or DVDs (where the data is copied from) works to stop error messages from popping up. Cyclic Redundancy Check (CRC) is a message that appears on your computer screen whenever your computer reads corrupted data. CRC basically detects an error in a file that is being read by your computer. This error message usually occurs when your computer tries to read data from damaged media such as a hard drive, CD or DVD.

When data is transferred to a PC, CRC ensures that the data, with numerous errors, does not reach the specified destination. This is why a damaged CD will not be copied to your computer.

Fixing CRC errors

Problems with external CD/DVD media
Many times, accumulation of dirt on a CD or DVD causes a CRC error. Cleaning this media with a soft cloth often solves the problem. A scratched CD or paper label on the disc can also be a problem. This is because scratches or marks prevent the data from being written to the disc correctly. Partially written discs are especially responsible for causing this error. To extract information from damaged disks, there are software applications very useful in this regard. These data recovery tools such as Lost digital images from damaged CDs and DVD discs.

Hardware problems
If the CRC error continues to appear even after running Disk Cleanup, then there is most likely a hardware problem. You need to check the cleaning of CDs and DVDs and clean them regularly. Find out whether these devices actually function correctly. Replacing the CD/DVD reader with a new one may solve this problem.

With software

In such cases, the system may display messages like "Invalid" Windows file» or » invalid win32′ application. But this is actually a CRC error.

Lost connection
Defective connections between the computer and the hard drive cause CRC messages to pop up on the screen. To fix a CRC error related to network problems, you need to check all connections to decode the problem. Sometimes, DVD/CD connections become disconnected and may affect the functioning of the device.

Hard drive problems
In many cases, a CRC message is displayed on the screen when the destination drive (hard drive) has bad sectors. So although DVD/CD is completely normal, this error can still occur. This happens because the location (hard drive) where you are trying to save the file has bad sectors. Check if there are bad sectors by executing the NUL command and launching the command line. In fact, this command reads the contents of a file saved on a CD/DVD. For example, if the DVD is on computer E, and the nicks.txt file in the DVD is stored in the tng\audio folder, then the command line will look like this:

E:\>cd tng\audio

E:\tng\audio>xcopy nicks.txt NUL

1 File(s) copied

Because the destination is not specified, it only reads the file. If the command is executed successfully, you will get the result as 1 file(s) copied, i.e. the file was read successfully, and as such there is no problem with it. This means that the hard drive is damaged due to a bad sector. In such a case, the solution is to either change the hard drive or burn the DVD on a different machine altogether.

Hard drive repair
If you are thinking about repairing your hard drive, you can run the repaired program to hard checks drive such as SpinRite. This program does two things. First, it retrieves data from the bad sector. Secondly, it marks all bad sectors so that data will never be written to them again in the future. Another option to remove errors from your hard drive is to run the CHKDSK command. This is a disk check with a command that identifies bad sectors and tries to restore readable information.

Run CHKDSK from GUI user (GUI)
Double-click the My Computer icon on your desktop. Select the hard drive partition you want to check. As we all know, letters are often used to name disk partitions. Depending on the size of your hard drive, it will have two or more partitions. Therefore, if your hard drive has 4 sections, you must run the CHKDSK command for each section to scan the entire hard drive.

Let's say you've selected partition D (called drive D) of your hard drive. Right click Click on the D drive icon and select ‘Properties’.

The Properties window will appear on your computer screen. Click the Tools tab to view Check Now.

Click the "Check Now" button.

The Check Disk window has two checkboxes: “Automatically fix system errors” and “Scan for and repair bad sectors.” Check both boxes and click the "Start" button to ensure that errors encountered during the scan are corrected immediately and data from the bad sector is recovered.

Important Note
Section C hard drive typically contains operating system files running in background when the computer is in use. Therefore, if you decide to run the CHKDSK command on the C drive, the scan is unlikely to start at all. In fact, you will see a pop-up window that conveys the message “Windows cannot verify this drive while it is in use.” This window appears if you have an operating system installed Windows system 7. The pop-up window also has a "Schedule Disk Check" button. Click on this button and the disk check program will be assigned after you restart your computer. In other words, you need to shut down your computer properly and start it again to run CHKDSK.

Run CHKDSK from the command line (CMD) To see the command prompt on the screen, firstly press in Windows button"Start". Now type “cmd” in the “Start Search” field and press the “Enter” key on your keyboard. You will be able to view command line utilities. Syntax CHKDSK command chkdsk [drive:] To search and recover data from bad sectors and correct other errors on the C drive, enter "chkdsk c: /r" in command line and press enter. To run the CHKDSK command on other disk partitions, replace 'C' with the letter that represents the partition of your disk.

However, if you are not interested in recovering data from bad sectors and want to fix errors, then type “chkdsk c:/f’. This command completely skips bad sectors when scanning the disk.

How long to wait for the CHKDSK /r operation to complete? This will depend on the size of the hard drive and the amount of damaged data. The larger the hard drive, the longer the scanning time will be. For example, the CHKDSK command, which runs on a 120 GB hard drive, will take about 10 hours. On the other hand, a 1 terabyte hard drive full of data may take 30-35 hours to complete the CHKDSK command. Recovering data from damaged storage As mentioned above, a CRC error appears when copying files from external media to a computer (hard drive) and indicates that there are bad sectors on the CD/DVD. Now a solution for retrieving data from external media. To do this, you need to go to the command line. Use the cd command to change the current working directory where the file is stored. Let's say user\public is the folder on your CD/DVD drive (on drive E) from which you want to copy the file.

E:\>cd File Location

E:\>cd user\public

The command line after executing the command looks like this - E:\user\public> pointing to our current working directory user\public.

Let's say nicks.txt is the name of the file where the data is stored. This file is stored in the (user/public) folder. Now we have to move the data from nicks.txt to another new location (say B:\newfolder). To do this, you need to use the xcopy command, which allows you to copy one or more files from one folder to another.

The syntax is as follows: xcopy source destination

So, now you need to enter a command in the command line that will copy the data and it will look like this -> E:\user\public> xcopy /c nicks.txt B:\newfolder

There is a high possibility that xcopy may stop copying files as soon as it reads errors from the source (user/public). To avoid this situation, you also need to use the “/c” parameter. This ensures that xcopy copies data continuously from the source.

If you want to create a copy of all files in the user\public folder, then instead of nicks.txt you must enter *.*.

So, xcopy will look like xcopy /c *.* B:\newfolder.

Another option is to directly copy the entire contents of the DVD/CD to a new folder on your computer. The syntax is as follows: xcopy /c E:\files C:\files /s /i

Here, the data from the files in the E drive folder (your computer's CD/DVD drive) is copied to a new folder, the so-called files, and located on the C: drive. The '/S' option allows you to copy all subdirectories located in E:\files.

CRC data error is quite common. The publication is intended not only for advanced users personal computer. Beginner users should also familiarize themselves with it. To begin with, let us give a typical example on the topic under consideration. A computer user is trying to make a copy from a DVD. At this time, a “CRC data error” pops up and the process is interrupted. What does this mean and what can be done to fix the problem?

In this case, failure may be caused by the following reasons. The first is damage or, to put it more simply, a DVD or CD. The second is file corruption. In the second case, as a rule, we are talking about files packed into archives. For example, a PC user tries to download an archive from the Internet big size, but faces the problem discussed in our article.

Usually, such files are simply deleted and more and more attempts are made, which, with time, patience and perseverance, should be crowned with success. There are other examples of actions that cause a CRC error. In particular, such a problem may arise in Windows time XP. In this case, the error is issued by the system in the same place.

The user looks at the screen, and when there are, say, 35 minutes (or other time) left before the OS installation process completes, he sees a sign with the appropriate text: “One of the components required to continue the OS installation was not installed. There is an error in the CRC data.” . We will consider this option possible ways resolving the issue.

As a rule, OS installation is performed from a disk or directly from the Internet. When installing from a CD, you can first try to wipe it gently - clean it with a soft cloth. If the process was carried out from the Internet, most likely, some setup files were copied to the hard drive of a personal computer incorrectly.

In this case, you should use the disk check program and try to install the OS again. But sometimes PC users complain that even after the hard drive has been formatted and partitioned, a CRC error still appears in XP from a DVD ROM. You can try to follow this advice: "You need to rewrite the OS distribution at a lower speed, since the problem could be caused by high speed records."

If this recommendation did not help, then it is better to install Windows XP not from a disk, but from a flash drive. Then the issue will be resolved guaranteed. Let's return to the occurrence of an error caused by file corruption when trying to copy information. They will help you fix it special programs- utilities, some of which are discussed below.

The PC program Portable Any Reader is designed to read data and copy information from all kinds of media that are damaged, or if any other difficulties arise during reading (hard to read). Any Reader is especially relevant when working with Wi-Fi, since its functionality is not affected by connection loss or reading errors. There is a function that allows you to specify the estimated number of attempts to read from damaged storage media.

As another useful utility that will help solve a problem such as a CRC error, we can recommend Recovery Toolbox for CD Free. This free program, specially designed to recover damaged data from various storage media. With its help, you can recover/read files of almost any type if the following problems occur:

• The storage medium is physically damaged.
• The media format has been damaged by the media recording program.
• operating system gives an error (including a CRC error) when trying to access information carrier or reading from it.

Recovery Toolbox for CD Free is equipped with a comfortable, intuitive interface, simple and convenient to use.

Even a novice PC user can successfully use the information provided, and we can only wish you good luck!

Some users, when downloading (or installing) files from any sources, may encounter a CRC error, which manifests itself with the message “Error in data (CRC)”. This problem usually occurs when the system detects a mismatch in the control data of the downloaded file, resulting in an error message in the CRC data. In this article, I will tell you what a CRC data error is, under what conditions it occurs, and also explain how to fix it.

Screenshot of the “Location is not available” error

What is CRC

Before we begin to describe what to do in a situation where an error occurs in the CRC data, it is worth explaining what a “CRC” is.

As is known, CRC (Cycle Redundancy Check - translated as “cyclic redundancy check”) is an algorithm for creating and verifying a “file checksum”. The latter is used to monitor the integrity of transmitted data in order to prevent damage or loss.

This algorithm, based on cyclic code, calculates the checksum of the file and adds it to the body of the file itself. When downloading (copying) this file The system, having an algorithm for calculating the checksum, checks the correctness of the received data, and if inconsistencies occur, issues a CRC error message (data error - cycle redundancy check).

The CRC algorithm was invented back in 1961, has undergone several qualitative improvements, and is now a universal tool for checking the integrity of received data.

Features of the CRC error

As for the reasons for this dysfunction, the specific causes of the CRC error may be as follows:

• Loss or damage to any of the network data packets during transmission;
• Loss or corruption of data on the hard drive (for example, due to bad sectors);
• Physical damage optical disk with information (CD, DVD, etc.);
• Violation of the integrity of the system registry;
• Random failure during program installation;
• Incorrect file configuration and so on.

To display the CRC code, there is such a program as HashTab, which, after its installation, in the properties of the file itself (right-click on the file, then select “Properties”) displays the values checksums of this file.

Error in CRC data - problems with hard drive

So how do you fix the CRC error? Since it regularly happens due to problems with hard drive access, I recommend doing the following:

Step 1: Recover lost data on your hard drive. If this problem arose when trying to gain access to any file on the hard drive, then it is worth using various programs to recover lost data. In particular, you can try software products such as Power Data Recovery or BadCopy Pro, designed specifically for the tasks I’m considering.

For example, to use Power Data Recovery, you need to download and install the application, select “Damaged Partition Recovery” in the menu, and perform a Full Scan. If lost data can be recovered, then, first of all, you will need to copy it to a reliable and secure medium.

Action 2. An alternative option for restoring access to data on the hard drive is to use system utility disk check.

1. Go to Explorer, right-click on the problem drive (for example, C:), select “Properties” in the menu that appears.
2. Go to the “Tools” tab, click on “Run check”, check the two check disk options, click on “Ok”, and then restart the computer.
3. After rebooting, the system will automatically run a data integrity check on the hard drive and try to recover damaged sectors (this may take some time).

Action 3. You can also run the command line as an administrator (click on the “Start” button, write cmd in the search bar (without pressing enter), right-click on the same result that appears at the top, and select “Run as administrator”). On the command line you need to write:

chkdsk c: /r /f - (instead of “c:”, enter the name of another problematic disk if necessary) then press enter and wait for the check to complete.

How to fix CRC error - alternative options

In addition to problems with hard drive, the CRC error can occur for other reasons. Therefore, to fix the CRC error, do the following:

• If this error arose when installing a game, it will be easier to download its image again (or the program files themselves) from another source using proven level programs Download Master, perhaps this will help get rid of the CRC error.

Conclusion

If you have an error in the CRC data, then, first of all, determine the conditions under which this error occurred. Most often it occurs when trying to download and install disk images (or programs themselves) from the network. An effective remedy in this case would be to use alternative resources to download these files, which, in most cases, helps to effectively solve this problem. If you are dealing with hard drive dysfunction, then you need to use programs like Power Data Recovery or BadCopyPro, which can help restore access to the files you need.
