crc error what to do. Why does a CRC error occur and how to fix it. System utility for disk diagnostics

Very often when copying information from a CD/ DVD discs system gives CRC data error. What does it mean? This means that, unfortunately, your disk is damaged and the information cannot be copied. But don't despair - there is a way out! There are programs, which can read information from hard-to-read or damaged disks. We’ll talk further in this article about how to copy information from such disks.

CRC error means that your media, that is, the disk, is not readable due to mechanical damage. Or the drive on the computer is quite old and worn out. First, try copying the disk on another computer and if a reading error occurs again, then the disk itself is actually damaged.

In this case, you need to inspect the disk for dirt and damage. You can lightly wipe the disc from dust and fingers, do not leave streaks and without fanaticism! If there is damage to the upper part of the disk (where the inscriptions are written), you need to sketch it with a marker (sometimes it helped).

Next, you need install one very useful program in such cases - BadCopy Pro. The program can read information from damaged disks. It implements special algorithms for reading bad sectors, due to which the checksum does not match and pops up CRC error. But still, there is no guarantee of complete copying. For example, for video files this is not critical. When viewing, you will hardly notice a couple of bytes of missing (not copied, damaged information). At most, a couple of incomprehensible spoiled frames may appear. But still, the information will be copied, and you will be able to view it, but this is almost impossible to do on a damaged disk! Such disks twitch and freeze - and sometimes for a long time.

The BadCopy program can recover data from unreadable disks, floppy disks, hard drives, flash drives, etc. The program allows you to recover many types of files: graphic, text documents, executable files, archives, etc.
A simple, intuitive interface and step-by-step dialog wizard allow even a beginner to achieve the goal.

If the media is very damaged, be patient, but there is no guarantee of 100% recovery of information. It all depends on the degree of damage to the disk. The program copies all recovered data to a specified folder on your hard drive.

The program will also be able to help when needed:

Access files that cannot be read.
Recover lost photos from digital cameras.
Recover files deleted from a floppy disk as a result of quick formatting.
Recover lost files on floppy disks, CD/DVD-R and CD/DVD-RW disks.
Recover data recorded during each session on CD/DVD-RW discs.

That's all - 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.

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 you know, CRC (Cycle Redundancy Check) is an algorithm for creating and checking 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, it 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.

CRC technology

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.);
Integrity violation system registry;
Random failure during program installation;
Incorrect file configuration and so on.

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

Interface Power programs Data Recovery

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

Go to Explorer, right-click on the problem drive (for example, C:), select “Properties” in the menu that appears.
Go to the “Tools” tab, click on “Run check”, check the two check disk options, click on “Ok”, and then restart the computer.
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).

Checking the disk for errors

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”). IN 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 until the check is completed.

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 occurs 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 dysfunction of the hard drive, then you need to use programs like Power Data Recovery or BadCopyPro, which can help restore access to the files you need.

Fixing hard drive CRC error

A data error (CRC) occurs not only with the built-in hard drive, but also with other drives: USB flash, external HDD. This usually happens in the following cases: when downloading files via torrent, installing games and programs, copying and writing files.

Ways to fix CRC error

A CRC error means that the file's checksum is not what it should be. In other words, this file has been damaged or changed, so the program cannot process it.

Depending on the conditions under which this error occurred, a solution to the problem is formed.

Method 1: Using a working installation file/image

Problem: When installing a game or program on a computer, or when trying to burn an image, a CRC error occurs.

Solution: This usually happens because the file was downloaded with corruption. This could happen, for example, if the Internet is unstable. In this case, you need to download the installer again. If necessary, you can use a download manager or torrent program to avoid connection interruptions during downloading.

In addition, the downloaded file itself may be damaged, so if a problem occurs after downloading again, you need to find alternative source downloads (“mirror” or torrent).

Method 2: Check the disk for errors

Problem: There is no access to the entire disk or installers saved on the hard drive that worked without problems before do not work.

Solution: This problem may occur if the file system hard drive is impaired or he has bad sectors(physical or logical). If bad physical sectors cannot be corrected, then other situations can be resolved using programs to correct errors on the hard drive.

In one of our articles we already talked about how to fix problems file system and sectors on the HDD.

Method 3: Finding the correct distribution on torrent

Problem: Downloaded via torrent installation file does not work.

Solution: Most likely, you downloaded the so-called “broken distribution”. In this case, you need to find the same file on one of the torrent sites and download it again. A damaged file can be deleted from your hard drive.

Method 4: Check CD/DVD

Problem: When trying to copy files from a CD/DVD disk, a CRC error appears.

Solution: Most likely, the surface of the disk is damaged. Check it for dust, dirt, scratches. If there is a clearly expressed physical defect, most likely nothing will be done. If you really need the information, you can try using utilities to recover data from damaged disks.

In almost all cases, one of the listed methods is enough to eliminate the error that appears.

We are glad that we were able to help you solve the problem.

Cause and solution for crc error in data

The crc error occurs when the user tries to copy a certain file to his HDD or other storage medium.

The manifestation of this trouble can be associated with two main root causes:

Size checksum mismatch.

Some damage to the hard drive being used.

There is a way out of any of these situations that can lead to a crc error.

Treatment of the first option

The crc error, associated with a mismatch in the size of the downloaded file and its theoretical source, usually occurs when using a torrent. For example, such a discrepancy can lead to the entry “crc data error when installing the game” at any stage of installation, when a person has already prepared himself for a pleasant pastime.

The solution to this problem is quite simple, although it will require the user to waste his time:

Enable torrent client.
Remove problematic files from distribution (select with the mouse and click on the “del” button).
Erase already downloaded information from the PC hard drive.
Search online and find a better giveaway. Recommends paying attention to reviews from other people who may have identified this problem earlier, which will save time.

Fixing the second type of this problem

If a crc data error appears on an external hard drive or on its stationary counterpart, then a little more effort will be required.

The initial step in how to fix a crc data error related to a drive is to perform a small verification procedure:

Select the disk you want to record to.
Click on it right click mouse so that you can go to the properties menu.
Go to “Service”, where you select the first line that gives you the right to start checking the disk.
Wait for the result.

After this step, it is recommended to perform defragmentation. This process starts in the same place, just one line down. Typically, such a procedure requires a significant wait, so you will have to be patient or devote yourself to something else.

If the two steps described above could not positively solve the problem, then you will have to use special programs. How to treat crc hdd data error? Typically, HDD Regenerator, Victoria or similar applications are used for this. After installation, you should go to the software settings, where you can set the parameters so that the application starts checking immediately before the operating system loads.

Only if none of the proposed options helped to cope with the situation, you should seek help from specialists who may advise changing the hard drive.

How to fix an error in CRC data?

A data error (CRC) occurs when the checksums of the file accessed by the utility do not match. This could mean that the file has somehow become modified or even corrupted.

This problem mainly occurs when you install applications and games; make copies of the file located on the disk; write any disc or download via torrent utility. Let's now look at the main causes of errors in crc data.

Error in crc data occurs when burning a disc

You need to check the checksums of your image. Especially if you said it from the Internet. To do this you need to download the HashTab utility. After installation, it will appear in the properties window new inset called “File Hash Sums”. Using it, you can compare the hash amount of the image with the amounts displayed on the site.

If you find that these amounts do not add up, you will have to download this image again. It is best to use the Utorrent utility for this. When downloading files, it itself calculates their checksums. If you download files from direct links, then you can use the Download Master utility.

Error in crc data occurs when copying from drive to HDD

Most likely the error occurs because the disk you are using is damaged or has dirt on it. Try cleaning it and try copying from the disk. If all else fails, but you really need the files on the CD, you can use the BadCopyPro utility.

An error in crc data occurs when installing utilities or games

The most the best solution will re-download the image you downloaded. As mentioned above, it would be best to use utilities such as Download Master (for direct links) and Utorrent (for torrent downloaded).

Here we will need to perform a check on your file system. To do this, do the following:

Press the Win+R key combination and enter the cmd command. This will take you to the Command Prompt.
In the Command Line, enter chkdsk c: /r /f (the letter C is your logical drive). This command will start the process of checking your hard drive for various errors and fixing them.

Error in crc data occurs when using Utorrent

Try updating the utility.
Get rid of problematic distribution in the utility.
You will have to delete the undownloaded file.
Try to find another similar distribution and try to download it.

If you are dealing with dysfunction of the hard drive, then you need to use programs like Power Data Recovery or BadCopyPro, which can help restore access to the files you need.

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:

The file you are trying to open or copy is damaged.
Damaged media, flash drive, portable external hard disk, etc.
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”.
