Yes - life consists not only of white stripes. There are also troubles in it - small, medium, large .. and a CRC error. What type can this disgrace be attributed to, which can increase the level of adrenaline in the blood of a user who decides to have a good time at his PC and download something extremely interesting to his HDD but unable to complete this much-needed process?

There are two options for this problem:

• Acceptable - which is associated with a mismatch of checksums.
• More serious - which is caused by problems with the hard drive.

Do you think everything is bad? Oh, come on - Dr. Ai-Tupit will come to your rescue here too!

Solving the CRC error in the first case

So, first of all, you need to think - after what does a CRC error occur? Believe it or not, in the vast majority of cases, its root cause is the use of torrents.

Yes, of course, torrent is our everything. However, even this technology sometimes creates some annoyances. What is most offensive is that they can show up much later, for example, at the installation stage (about forty minutes after the start of the installation of the interactive novelty), the message “CRC data error when installing the game” appears. And even if you bang your head against the wall, even bite off the floor of the keyboard, or feed a computer mouse to your beloved cat ten times, nothing will help.

Is there a way out? There is! It consists of just a few steps, although they will require the user to waste time again:

• Launch torrent client.
• Remove previously completed downloads from it (specifically, the one that always ends with the inscription “CRC error” during installation).
• Do the same with the recorded information on the hard drive of your favorite computer.
• Find a better distribution and, of course, put it in the download order.

By the way, a good distributor always reports the checksum of the size of the downloaded file. Therefore, the user, who has already been burned once, has the opportunity to check the theoretical and real dimensional characteristics in order not to get into the same trouble twice.

CRC error - fixing the second option

So, there was a CRC data error on an external hard drive or traditional equipment that is gathering dust in the computer case. Solving this problem will require a lot of effort from the user, however, nothing is more difficult than homegrown Bill Gates can handle.

The first stage is a banal check that can tell you how to fix an error in the CRC data.

Everything is done easily and simply:

• Choose exactly the disk that, when trying to write information, leads to a similar situation.
• Go to "properties" - "service" - "check". The right mouse button will help you.
• Try to digest the information that will be displayed on the monitor screen when it is completed.

In principle, do not bother - go straight to disk defragmentation. Moreover, the start button for this process is located very conveniently - in the same menu from which the check was performed.

Here you can smoke, cook borscht, cook herring under a fur coat, chat with your favorite hamster, learn how to make paper airplanes - defragmentation is a very long and boring process.

Completed, checked .. did not help. What to do? How to treat HDD CRC data error? The main thing is not ... well, you understand - not to do what is forbidden to do in the tank, but to calmly continue the treatment procedures. Do not panic, but download one of the special programs, such as Victoria or HDD Regenerator. The main thing is not to poke, but immediately change the settings of the programs so that they begin to perform their useful work before the operating system starts itself.

A CRC data error can occur during any kind of copying of information, whether it is unzipping, transferring data from a media, or downloading data from the Internet. Let's take a step-by-step look at all the possible options for the occurrence of this error, moving from the particular to the general.

Archives

This is one of the very first cases where a failure can occur. The archiving process is quite complicated, so the slightest failure can lead to archive corruption. If you get the message "CRC error. The file is corrupted", then most likely the archive was corrupted after it was created. That is, you did not fully download it or copied it from the data carrier. Another version of problems with the archive is that a hardware failure occurred directly during the creation of the archive. Perhaps there was a power failure, the processor was "overclocked" by oneself, or low-quality memory strips were installed. In this case, the information cannot be recovered.

Internet download

If you download any information from the Internet, then when accessing the received data, a crc error may also occur. This, as in the previous case, means that the file is broken. The one who posted the file on the network did not do it completely. Perhaps the download was interrupted through no fault of his, but the data on the network is not complete. The solution to this problem is to look elsewhere for the data you need. Delete the already downloaded file and start downloading. If you are using a torrent, then remove the torrent file from the download along with the bit of downloaded information.

Transfer

Sometimes when copying information from a disk, flash drive and external screw, files can also be damaged. This also causes a "CRC Data Error" message to appear. What does this mean when working with optical discs?

In 99% of cases, this means that your drive is damaged. And not at the logical, but at the physical level. Try to gently wipe its surface from dust and fingerprints, but do not leave new ones. Another option is to try reading the disc on another computer. If it helps, then there is probably a problem with your drive. If there are scratches on the upper (with a picture) part of the disc, you can try to sketch them with a marker (the old-fashioned way sometimes helps).

badcopy

To read and restore broken data, the BadCopy program is used. If you see a "Error in CRC data" message when working with disks, it will help you save information. Or at least consider part of it. For example, with its help, you can pull out a video from a damaged disk. Since disk damage occurs on 1-2% of the surface, then the data will be distorted by about the same or even less. Thus, if you save the video with the help of this program, then a couple of frames with unclear graphics will be noticeable during viewing, but otherwise the whole movie will be safe and sound. If the disk is very badly damaged, the program may take quite a while to complete. long time, and not the fact that the result will be 100%. In general, this program is capable of performing the following actions:

• Get access to unreadable files.
• Restore photos on the camera.
• Recover data deleted using quick format.
• Recover lost files on various storage media.
• Read data if it has been deleted from a rewritable optical disc.

HDD

The last and most dangerous reason for which a CRC error can appear is a problem with your hardware and pre-installed software.

In any case, remember that no one canceled the preventive care of your computer. Install CCleaner and clean your system regularly. Do a defragmentation at least once every six months. And, of course, correctly delete installed programs, then the CRC error will not appear due to the fault of your equipment.

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 entry “crc data error when installing the game” 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:

1. Enable torrent client.
2. Delete problematic files from the distribution (select with the mouse and click on the “del” button).
3. Delete already downloaded information from hard drive PC.
4. 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:

1. Select the drive you want to write to.
2. Click on it with the right mouse button so that you can go to the properties menu.
3. Go to the "Service", where select the first line that gives the right to start checking the disk.
4. 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.

Very often, novice "experienced users" decide to install the OS themselves, but they do not always get it right the first time. At Windows installation the user may encounter various problems, such as an error 0x0000007b, data error (CRC) and some others, but one of the most common problems still remains "error copying files". This error can occur for several reasons, let's try to consider them in order of ease of elimination and probability of occurrence.

1 reason . The most common and easily remedied cause is a CD or DVD disc that has been badly recorded or has already been damaged by time and scratches.
Decision: Record only on high-quality discs, the service life of which is more than six months. Company discs Verbatim and TDK are quite suitable, their service life is more than three years.

2 reason . Lifetime of many CDs, DVD drives is only a year and a half. Listen to the drive, if the sounds in it are repetitive, and the files are copied slowly, especially if the computer or laptop is old, then the reason is most likely in it.
Decision: Oddly enough, a freshly burned disc can be read even on the most dead CD drives, so be sure to try changing the disc. If attempts are in vain, then you can reanimate the old CD, DVD drive by increasing the power supplied to the laser, but this is more of a way for the pros. There is a lot of information on the Internet about how to do this. If this method does not suit you, and there is no other CD or DVD drive at hand, then there is only one way out - to install the system from a flash drive.

3 reason . RAM.
Decision: This happens extremely rarely and the likelihood that a broken bar is to blame random access memory almost none, but before moving on to the next reason, it makes sense to check it with a program Memtest 86+ 4.20. You can find this program on the assembly Zver CD 2013.3.

4 reason . If you have tried several discs, are confident in your CD, DVD drive, and the error keeps popping up and popping up or in addition to " error while copying files" you see on the screen "data error (CRC)", then you are in wait for not the most common, but the most unpleasant error - a hard disk error. This happens when problems arise not at the software level, but at the physical level, when the surface of the hard disk pancake is partially destroyed.
Decision: The easiest way, of course, is to buy a new hard drive from a store, but there are ways that can give your hard drive a second chance, which we will now consider. First way suitable if there are very few such places on the surface of the hard disk. To do this, you need to check and fix the surface of the hard drive special utility Victoria 3.51, it is in the assembly Zver CD 2013.3. Second way suitable if there are many such bad sectors and it is not possible to fix them. In this case, we simply cut off a part of the hard disk with bad clusters (bad parts of the hard disk), so that the computer does not access the damaged surface during operation. To do this, you need to use the program Acronis DD Home 11(we are also looking for it on Zver CD 2013.3) and we simply delete the first 50-300 GB of the hard disk (I advise one third of the total volume), and create a partition / partitions in the rest of the hard disk, after which we put Windows on this partition. If you have restored your hard drive and installed Windows on it, you should not use the partitions of this hard drive as a long-term storage of important data for you.

The crc data error can occur on both the main and external hard drive, and the causes are the same. Fortunately, there are solutions to this problem, some can be done without much effort, while others require physical repairs. In this article, we will guide you on how to fix external hard drive crc data error by providing all possible solutions.

Hard disk damage

If you get given error if you include almost all files, then it is quite likely that the problem is damage to the media. Check the hard drive for errors in Properties. If the hard drive is physically damaged, then it is likely that it will not be possible to use it in the future. Take the hard drive in for repair, and use BadCopyPro to restore files.

crc error when using torrent

If this error occurs when installing or launching files via a torrent, then the cause may be a size checksum mismatch. In most cases, this is due to broken hands, in which the game or program is not downloaded to the end. To fix a similar problem, you will have to delete all files with errors, as well as the distribution. Next, find another torrent with the same files and try installing it. When choosing a distribution, pay attention to the number of seeds and comments, so as not to accidentally run into broken files again.

Also crc error when using external drive can happen due to a momentary disconnection while downloading. Try not to download any files directly to external hard disk, as even if the wire is disconnected from it for a short time, a failure may occur. This happens extremely rarely, but it is better to download files first to the main hard drive, and only then to external media.

Viruses

Some malware also has ways to cause the crc error by corrupting some or all of the files on the external drive. To clean the disk from viruses, use antiviruses such as Kaspersky, Avast or 360 Total Security. As a last resort, format the drive if no viruses can be found.

Data recovery software

If the hard drive is damaged and needs to be replaced, and the files are very important to you, then you can use special programs for this. The most famous and at the same time free is the Recuva program. With it, you can recover all deleted or damaged files on your hard drive and flash cards. You can also recommend other programs, such as HDD Regenerator, Victoria, PhotoRec or the above mentioned BadCopyPro.

Summing up

Now you know how to fix external hard drive crc data error. If you are still unable to fix the crc error, then take the external hard drive to a specialist. In most cases, they restore the disk and, accordingly, the files on it. Good luck!
