Crc data error while copying. Fixing the hard drive CRC error. Hard drive problems

The CRC data error most often occurs when a user copies data or burns an image downloaded from the Internet to a disc. This is a common bug that occurs due to a mismatch between the checksums and the file size.

What is CRC

The abbreviation CRC stands for cyclic redundancy check. Translated into Russian it sounds like this: cyclic redundancy code". This is an algorithm for calculating checksums. With it, a computer device checks the integrity of the data.

This is the application that detects faults in communication technology and protects the computer from them. Works through the mathematical properties of the cyclic code.

Therefore, when the computer detects a checksum mismatch, a CRC error pops up on the user's screen.

Why does the error occur

Often an error in the CRC data appears when copying archives or files from one local drive to another. This usually happens when the failure occurred before the copy process. For example, the information was not fully downloaded from the Internet, or the archive has been corrupted by the person who packaged it or placed it on the website from which it was downloaded.

IN archiving process there could also be a hardware failure. Problems with the RAM installed on the computer can also contribute to the appearance of this bug.

Here are some other issues that cause the error to occur:

physical damage carriers;
violation in the system registry;
crashes when installing programs;
data reserved password
wrong configuration files.

One of the main causes of cyclic redundancy problems can be the presence of bad sectors(damage) on the hard drive.

Hard drive problems

If there are a lot of bad sectors on the hard drive, which lead to an early failure, information can fall into these sectors, which can also cause problems with initialization. Then it is very difficult to pull out the data intact, and sometimes even impossible. The Bad Copy program can help in this matter.

In order to fix a CRC error on a hard drive or flash drive, it is recommended install utility to the computer and run. Then take the following steps:

If this does not help and the next time you copy, the scoreboard with a bug message appears on the screen again, then recommended to defragment HDD.

To do this, download any defragmenter. For example, O&O defrag .

Install it to your hard drive and run. In the window that opens, click on the " start” and the utility will start defragmenting. We'll have to wait a bit.

Also possible problems with indexing files. To check it is better to disable it:

Another troubleshooting method would be error checking. To do this, you need to repeat the same steps as in the previous paragraph, only in the window that opens, go to the tab " Service' and click on the '' button.

Possible error options

If everything is fine with the hard drive, then the root of the problem may lie in misbehaving utilities.

For example, in uTorrent, if such an error appears as in the photo, then most likely the user has downloaded beaten distribution.

To remove this bug, you need to go to the torrent tracker and download the necessary information from another distribution.

If a CRC bug appears when transferring data from a CD or DVD drive, then most likely the optical media is dirty. You should take it out and wipe it with a dry cloth or a special cloth. If it has severe scratches, the error cannot be corrected. This disc can be thrown away.

The appearance of a CRC error when installing a game indicates the following types of problems:

downloaded damaged file. This happened because the internet was unstable at the time of download. It is recommended to download or download from another distribution. The problem of a broken distribution is described above;
file was not downloaded to end. This happens when the connection is interrupted.

It is recommended to use torrent trackers. Since the download stops on them if the connection is interrupted. And it starts again when the connection between the Sids and the Pyrrhas is established. That is, the user will always receive the file in full.

On torrent trackers, the chance to stumble upon a broken distribution is also very small.

Many users are familiar with the situation when the system gives various errors. How to treat CRC hdd data error? What caused her appearance?

As a rule, it occurs when copying CD / DVD information and indicates damage to the disc or the loss of the ability to make the necessary copies. Naturally, there is nothing pleasant in this, but you should not panic about this either. Thanks to the existence of special programs, you can fix the problem and read data that contains damaged disks.

Why does CRC hdd error appear?

The reason for the appearance may be mechanical damage to the disk or its "hackneyedness" due to its long service life. To determine the exact cause of the error and the condition of the disk, you can try copying it on a third-party computer. If the error repeats, we can talk about damage to the media itself.

If there is damage in the part of the disk where the inscriptions are made, you can use a marker and sketch them. Do not be surprised, but sometimes such a measure is effective!

BadCopy Pro

The very useful BadCopy Pro program, which we recommend installing, will help to fix the problem. Thanks to special algorithms that recognize bad sectors, the program has the ability to read information from damaged media.

Using the BadCopy Pro program, you can recover information from unreadable disks, floppy disks, hard drives, flash drives, etc. The program provides recovery of graphic, text, executable files, archives, and so on. The presence of a simple, clear and convenient interface allows even beginners to use this program.

If the disk is severely damaged, recovering information will require your patience and time. The chance of success depends on how badly the media is damaged.

Using BadCopy Pro you can solve the following tasks:

access unreadable files
recover lost photos on digital devices
recreate files from a floppy that were deleted by a quick format
recover lost files on floppy disks, CD/DVD-R and CD/DVD-RW, CD/DVD-RW discs.

If you are not sure that you can cope with the "treatment" of the hard disk yourself, contact the service center for qualified help. I wish you success!

The CRC error occurs very often. This is the cause of frustration for many PC users. As a rule, it appears at the moment when we want to run a CD / DVD disc in the CD drive. What should I do to get rid of this error and make full use of the software contained on the supplied disc?

In order to get rid of the annoying CRC data error, you must first download special software from the network. There are several free programs that will help us in fixing the said CRC error. One of the easiest to use and very effective program - Unstoppable Copier.

In general, it was created with the idea of data recovery from various types of media, including CDs and DVDs. Since most often mechanical damage to the disk causes a CRC error. Unstoppable Copier after launch, it “fills in” the missing places on the disk, so that it can all be played back.

If you have already downloaded and installed the proposed program, then proceed to the action. First, we copy all the files from the CD / DVD to the hard drive of our computer. This will allow you one of the Unstoppable Copier program options. To do this, run the program, install the damaged disk in the drive.

In the main menu of the application, select the desired copy path (disk path), and then select the location on the disk where the selected data should be saved. Before that, in the settings tab, we can manually set the Speed / Quality parameter. The faster the data is copied, the more likely it is that the CRC error will reappear. So, if you have a little more free time, we recommend setting the minimum file transfer speed.

Click the copy button and you're done. All files will be written to the hard drive. While copying the data, the missing spaces will be padded, so that when you run the copied files to the hard disk, no CRC error will appear. Ready! Now we can take full advantage of previously unavailable software.

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

What is CRC

Before starting to describe what to do in a situation where an error occurs in the CRC data, it is necessary to explain what "CRC" is.

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

This algorithm, based on the cyclic code, calculates the checksum of the file and adds it to the body of the file itself. When loading (copying) this file, the system, having a checksum calculation algorithm, 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 gone through several qualitative improvements, and is now a universal tool for checking the integrity of received data.

CRC Technology

Features of the occurrence of a CRC error

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

Loss or damage to any of the network data packets during their transmission;
Loss or corruption of data on the hard disk (for example, due to bad sectors);
Physical damage to the optical disk with information (CD, DVD, etc.);
Violation of the integrity of the system registry;
Random failure during installation of the program;
Invalid 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 checksum values of this file.

CRC Data Error - Hard Disk Problems

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

Step 1: Recover lost data on your hard drive. If this problem occurred while trying to access any file on your hard drive, then you should use various programs to recover lost data. In particular, you can try in practice such software products as Power Data Recovery or BadCopy Pro, designed specifically for the tasks I am 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 the lost data can be recovered, then, first of all, you will need to copy it to a reliable and secure medium.

Power Data Recovery interface

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 a check", check the boxes next to the two check disk options, click on "OK", and then restart your computer.
After rebooting, the system will automatically enable the data integrity check on the hard disk, and will try to repair bad sectors (may take some time).

Checking the disk for errors

Step 3. You can also run the command prompt 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 the hard drive, a CRC error can occur for other reasons. Therefore, to fix the CRC error, do the following:

If this error occurred during the installation of a game, it will be easier to download its image again (or the program files themselves) from another source using proven Download Master level programs, this may 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 the programs themselves) from the network. An effective means in this case will be the use of alternative resources for downloading these files, which, in most cases, helps to effectively solve this problem. If you are dealing with dysfunction in the hard drive, then you need to use Power Data Recovery or BadCopyPro level programs that can help restore access to the files you need.

Fixing a 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 checksum of the file is not what it should be. In other words, this file has been corrupted 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 write an image, a CRC error occurs.

Solution: This usually happens because the download was corrupted. This could happen, for example, with an unstable Internet connection. In this case, you need to download the installer again. If necessary, you can use a download manager or a torrent program so that there are no disconnections when downloading.

In addition, the downloaded file itself can be corrupted, so if a problem occurs after re-downloading, you need to find an alternative download source (mirror or torrent).

Method 2: Checking the disk for errors

Issue: Can't access the entire drive, or installers stored on the hard drive that worked without problems before don't work.

Solution: This problem can occur if the hard drive's file system is corrupted or it has bad sectors (physical or logical). If bad physical sectors cannot be repaired, then other situations can be resolved using error correction programs on the hard disk.

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

Method 3: Finding the correct distribution on the torrent

Problem: The installation file downloaded via torrent 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. The damaged file can be deleted from the hard drive.

Method 4: Check CD/DVD

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

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

In almost all cases, one of the listed methods is sufficient to eliminate the error that has appeared.

We are glad we were able to help you resolve the issue.

Cause and solution of crc error in data

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

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

Size checksum mismatch.

Some damage to the used hard drive.

From any of these situations, which can lead to a crc error, there is a way out.

Treatment of the first option

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

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

Enable torrent client.
Delete problematic files from the distribution (select with the mouse and click on the “del” button).
Erase already downloaded information from the PC hard drive.
Do a web search and find a better distribution. Recommends paying attention to the feedback of other people who may have previously discovered this problem, which will save time.

Correction of 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 here.

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

Select the drive you want to write to.
Click on it with the right mouse button so that you can go to the properties menu.
Go to the "Service", where select the first line that gives the right to start checking the disk.
Wait for the result.

After this step, it is recommended to perform a defragmentation. This process starts in the same place, just one line down. Usually 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? Usually, HDD Regenerator, Victoria or similar applications are used for this. After installation, you should go to the software settings, where you set the parameters so that the application starts checking immediately before the boot process of the operating system.

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

How to fix error in CRC data?

A data error (CRC) occurs when the checksums of the file accessed by the utility do not match. This may 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 crc data error.

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 net. To do this, you need to download the HashTab utility. After its installation, a new tab will appear in the properties window called "Hash sums of files". Using it, you can compare the hash sum of the image with the amounts displayed on the site.

If you find that these amounts do not converge, you will have to download this image again. The best way to do this is to use the Utorrent utility. When downloading files, she herself makes a miscalculation of 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 due to the fact that the disk you are using is damaged or has dirt on it. Try clearing it and try copying from the disk. If nothing worked out for you, but you really need the files on the CD, you can use the BadCopyPro utility.

Error in crc data occurs when installing utilities or games

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

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

Press the key combination Win + R and write the cmd command. This will take you to Command Prompt.
At the Command prompt, type 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 the problematic distribution in the utility.
You will have to delete the undownloaded file.
Try to find another similar distribution and try to download it.

How to treat CRC hdd data error?

1. Why does CRC hdd error appear?
1.1. BadCopy Pro

Many users are familiar with the situation when the system gives various errors. How to treat CRC hdd data error? What caused her appearance?

Portable storage media, solid state drives, flash drives and hard drives are devices for transferring and storing files. But sometimes when using one of these drives, the warning "Error in data (CRC)" occurs. This warning appears when trying to copy data between these disk devices, when installing applications and games.

For example, an error may appear if an external hard drive or flash drive is turned off for some reason while files are being copied.

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

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

If the error occurred with an external hard drive or flash drive, try a different port. The port might be bad.
Try copying the data to another drive. If the error still occurs, check on another computer.
If you cannot transfer to other media, the problem may be with the file. Most likely, a broken sector has formed in the place of its recording. If there is no access to it and it is important, we restore the bad sector with the MHDD or Victoria program, and safely transfer it to another medium.
The installation file of the game downloaded through the torrent client does not start? Most likely, a corrupted archive was loaded. Delete it and download a new one from other torrent sites.

Drive letter not showing

One solution is to check disk drives for file system errors using the Chkdsk utility. Testing requires a drive letter, but what if it doesn't show up in File Explorer. There are several solutions.

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

Press the key combination Win + E and see if the drive is displayed in Explorer.

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

Expand the "Disk devices" tab, check if the problem disk is in the list. If not, right-click and select Update Hardware Configuration from the menu.

If a yellow triangle with an exclamation mark appears in the Device Manager, it means that there is a problem with the drivers. Right-click on the unknown device and select Update driver, then search automatically.

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

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

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

Type diskpart, confirm execution with Enter.

Then type automount enable and confirm with Enter.

After rebooting the system, the letter should appear.

Chkdsk disk check

This is a built-in Windows tool for detecting file system errors and bad sectors, as well as fixing them.

If you receive a CRC error message when copying from a USB drive, check that external drive first. It makes no sense to spend several hours checking a hard drive only to find out that the problem is in a flash drive that takes several minutes to test.

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

After completion, the test results will appear.

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

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

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

System utility for disk diagnostics

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

Note: If "C" is selected, the computer will ask you to schedule a test. 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 Format

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

A quick format writes the boot sector and an empty file system table. At the same time, the files are not erased unless you copy something new onto them that will replace the old data.

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

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

Press Win+E to open the Explorer window. Specify the failed device, right-click and select Format.

Check the "Quick" item, and confirm the execution on Start.

Once the format is complete, launch the data recovery application. We recommend using the Recuva program, the free version of which is able to recover all data.
