There was an error when writing the disc. What should I do if Steam receives an error when writing to disk? Changing the download region

Nowadays it is difficult to find a teenager or even an adult who does not like computer games. Steam Valve is an online service platform for the production and distribution of programs and computer games.

Errors when writing to a Steam disk become a hot topic of discussion on forums for computer users. The functioning of the program fails due to a number of distortions in the digital “Steam” mode, which does not depend on the consumer.

In this article we will talk about common causes of software failures and how to deal with them.

Causes of Steam error when writing to disk

Technical problems occur for the following reasons:

insufficient space (memory) to download digital information;
error when writing to a Steam disk due to a background application (viruses, PC security blocks and Google Desktop);
violation of disk integrity due to logical destruction of Steam files;
It is illegal to write to disk when installing Steam without an administrator account.

What should I do if a Steam error occurs while writing to disk?

The problem resolution scheme is simple and consists of 13 ways to eliminate dysfunction:

Analysis of the Steam system. Valve product organizational settings automatically show corrupted files when there is a problem on the reported service platform. An exception is problems with the functioning of the hard drive in a personal storage device after examination.
Checking the hard drive. If there is insufficient memory on the main media, junk information is deleted with complete defragmentation on a regular basis. To save time, use Cleaner (cache clearing) to automatically transfer deleted data to the trash. Important information should be saved on another (backup) medium.
Re-analysis of the hard drive. If the result of the Cleaner program is positive, it is important to additionally double-check the effect after cleaning unnecessary elements. To do this, quarantined files are examined and destroyed after diagnosis.
Studying local media. An error when writing to a Steam disk can be resolved by finding bad blocks. Scheme for removing a block factor: right-click on a local block - “Properties” - “Service” - “Check”.
Checking the games folder. To avoid a Steam error when writing to disk, do not use the Cyrillic alphabet (Russian letters), since only Latin characters are allowed.
Change the properties of a shortcut. In this case, Steam is launched on behalf of the Administrator, because the problem cannot be solved in any other way.
Correction of location parameters. The process involves processing the PVN and changing it to European countries if the error when writing to the Steam disk depends on this blocking.
Disable some programs. Before fixing the problem, you need to temporarily disable your Anti-Virus and place the formatted game files in the “Exceptions” section. Antivirus programs in Windows 7, 8, XP format temporarily block the Steam system, recognizing its parameters as a malicious service.
Resource mapping. An error when writing to a Steam disk occurs when the location of the game files and the required object for downloading the program is inappropriate. To combine folders, the following scheme applies: Steam Settings – Downloads – Steam Libraries folders – adding a folder with existing games.
Disable RAM overclocking. The error when writing to the Steam disk will be resolved if you disable RAM overclocking.
Full data update. If it is impossible to resolve the issue using the listed methods, use the most radical option for blocking Steam errors when writing to disk. To implement this, a potential client of the service platform deletes his data in the form of a library of games and then restores his parameters in the required format.
Change of “filling”. Adherents of hard drives, if it is impossible to care for them untimely, should take a closer look at SSD receivers.
Contact technical support. It is carried out according to a template application and using a step-by-step algorithm. The shortest way to solve the problem is to contact Steam TP by creating a personal account in this system.

Rules for contacting technical support

Error when writing to disk Steam requires help from server specialists.

Step-by-step instructions for contacting them:

If you are wondering which drive to install Steam on (C or D), then definitely the one with the largest amount of memory. Steam creates a separate folder, which needs to fill the information space within the acceptable limits.

There are some nuances regarding drive C, which contains the main Windows database.

Conclusion: downloading games to disk D is more rational for further use, which can be renamed to Local Disk to avoid the use of Cyrillic.

Finally

Analyzing the state of your PC software will help you avoid problems even for a “dummies” on the Internet if you need to download a program.

The hard drive will not fail and the Steam error when writing to the disk will not occur if you use the above troubleshooting methods for prevention and troubleshooting.

When trying to install many popular games, PC owners often encounter various problems. A window with the message “An error occurred during unpacking: Unable to write data to disk” occurs when installing games such as GTA5, Sims4, the Assassin’s Creed series, Dark Souls 2-3, Dishonored, Outlast 2 and many others. In addition, the problematic library Unarc.dll is indicated which returned error code -11. Today we will tell you how to fix this problem.

Cause of error

The Unarc library itself is used to unpack compressed archives, hence the associated error “... The archive is damaged!” . There can be many reasons for its failure, but the most likely are the following:

blocking with security tools: antiviruses, Windows Defender;
the presence of Cyrillic characters in the name of the installer or the path to it;
temporary data storage failures;
damage to the installer or damage to the operating system image;
Damage to the hard drive or lack of free space for uploading;
lack of compatibility between the installer and operating system bits;
malicious software;
Damage to the installer's RAM or storage device.

How to fix Unarc.dll error -11

So, at the first stage, we will perform the simplest steps. However, these manipulations often solve the problem, so you should not ignore them.

After these steps, we try to install the game again. Please note that in addition to the antivirus, you need to disable the firewall, SmartScreen and Windows Defender (relevant for dozens). It is also recommended to reboot the operating system before starting the installation. The installation must be run with Administrator rights.

Unable to write data to disk due to damaged files

Here we will use more complex methods.

1. Separately download the problematic Unarc.dll library and place it in the system folder System32 or SysWOW64, the first folder is for x32, the second is for x64. Don't forget to add regsvr32 unarc.dll in the console. If it doesn’t work, try dropping the file into the root of the game you are installing.
2. Run the installer in compatibility mode with earlier versions of the operating system and other service packs.
Check the hard drive and RAM memory with monitoring utilities, check the hard drive for errors, defragment it, if the installer is on a flash drive, do the same with it.

Many people find the process of changing environment variables helpful. Here's a little instruction:

Does not exceed? There is another option

If the error continues to appear during the installation process, try redownloading the game. In the case of a repack, try a different assembly and resource. Attention (!), make sure that when downloading another repack, files are not lost. Here's how it's done:

Checking the hardware

If all else fails, and you can check the installation on another PC, try this. An error occurs - the reason is in the installer itself (or insufficient memory for installation and processing). There is no error - then you will have to check the hardware.

Blow dust off the structure, check the quality of connections and the condition of the connector. Next, change the RAM stick, try connecting the memory to a different connector. If no malfunctions appear, then check the operation of the computer with another hard drive.

Conclusion

The described manipulations should help fix the problem “An error occurred during unpacking: The data cannot be written to the disk. Unarc.dll -11", but if the source is not in them, and you have tried everything you could, then there are only 2 options left. The first is that the computer’s power is not enough to process the data stream. It is likely that outdated components and a low-power power supply are used. Second, there is not enough free space on the computer to store temporary files. Increase your free space, paying special attention to the disk with the operating system. Often the volume of unpacked data exceeds the size of the installer several times - you need to be prepared for this.

When we use Steam for the first time, we don’t even suspect that a bunch of errors and problems may fall on our heads when using this digital distribution service client. Various problems with connection, with loading, with launching various games and similar problems. In this article, we will look at one of the errors due to which you cannot normally download an update for some of your games.

For example, you download updates for Dota 2, the download begins, and then, at the very end of the download, a message suddenly appears on the screen in which you can see the following text:

An error occurred while updating Dota 2 (error writing to disk)

Quite an unpleasant situation, you will agree. Naturally, without downloading the released update, you will not be able to launch the game you need. Now we will try to correct this situation by going through five methods that even a PC beginner can do.

Clearing the Steam Download Cache

The first thing you should try to do in this situation is to clear the Steam download cache, as it can cause huge problems when downloading various content. It is to avoid these troubles that the cache clearing function exists. To do this, do the following:

Go to Steam Settings.
Next, go to the tab "Downloads".
Click on the button “Clear download cache”.
After clicking, a message will appear in which you will be told that you will have to re-login to your account. We agree.
Go to Steam again and check for a message .

Checking free disk space

The next tip may seem completely meaningless, since you know exactly how much free space you have left on your disk...right? You rarely think about this, especially if you have, for example, a 1TB hard drive on board. However, it is possible that you got very carried away and without noticing it, managed to fill all the free space. Check if you have at least ten gigabytes of disk space for the downloadable update. If not, then clean your disk and check if the message has disappeared .

Changing the download region

If you cannot download some content from Steam, then you can try the download region, as sometimes a glitch occurs due to which downloading in the selected region stops happening for some unknown reason. In this case, you can simply change your download region. To do this, do the following:

Go to "Settings" Steam.
Go to the tab "Downloads".
Change your download region to, for example, Switzerland or something similar.
Then restart Steam and check for the problem in person .

Checking the integrity of game files

Classic variant. There is always a possibility that there is something wrong with your game, i.e. its files were damaged, which is why the problem in the form of a message arose . To start the verification process, do the following:

Go to your Steam game library.
Right-click on the game you want and go to "Properties".
Then go to the tab "Local files".
Click on the button "Check the integrity of game files" and wait for the verification process to complete.

If any deviations were identified in the files, they will be corrected. After that, check again for the problem.

Disabling Antivirus

There is a possibility, albeit small, that your antivirus, for some reason, blocked the downloadable update for the game, mistaking it for a malicious element. This happens with moderate frequency among users, so it wouldn’t hurt you to check this possibility too. Disable your Anti-Virus for a while and see if loading occurs normally.

Reasons for Steam error when writing an application to disk

Although in the modern world hard drives are losing their leading positions to their receivers called SSDs, the majority of CIS users still use hard drives. After all, they are quite reliable, tested, and almost every dog knows how to solve problems with them. However, some users make quite stupid mistakes, which lead to undesirable consequences, for example, bad sectors of the hard drive. The topic of this article sounds like a Steam error when writing to disk. We'll have to explain that the hard drive is cruel only in words. It, like other types of information media, requires timely care.

Many users rarely do defragmentation, let alone low-level formatting after reinstalling the operating system. The error that this article is devoted to most often occurs due to a malfunction of the hard drive, be it bad sectors, clogged disks, or fragmented files. Therefore, it is worth starting to solve the problem with it, which we will do in the next part of the article.

How to fix Steam error when writing to disk

First, make sure you have free space on your hard drive partition. It is worth noting that some viruses clog the hard drive with false files, so before cleaning it is recommended to check the partitions with a scanner, after which we recommend clearing the browser cache, unnecessary files and the remnants of deleted programs - this greatly increases the amount of free space. If you are too lazy to do all this, then just install a cleaner program, for example, Cleaner.

Step-by-step treatment for Steam error when writing to disk:

Check your hard drive for free space. If there is no space, then delete what you don’t need.
Defragment your hard drive - this helps a lot to free up space.
Scan systems for malicious files.
Try disabling the Steam application at system startup. The launch options for this application are such that it immediately starts looking for updates and downloads them, so we recommend manually enabling Steam, and then immediately disabling updates and downloading only the necessary ones.
If all the options did not help you, but an antivirus is installed on your computer, then try deactivating it, some users point out the cause of the problem to the antivirus.

Finally

We hope that the Steam error when writing to disk does not bother you anymore, but for completeness, I need to say the following: careful and timely care of your computer will definitely save you from many problems, including with your hard drive.
