About Checksum Error WinRAR

What is WinRAR checksum error?

Checksum error in WinRAR, a RAR file error, appears when a few bytes get lost from RAR files or additional bits are induced. When this error occurs, it stops you from extracting RAR files.

What causes checksum error WinRAR?

After looking into many cases, we find some common causes for the WinRAR checksum error.

• Improper download: Due to improper Internet connection or low Internet connectivity, the .rar file won’t be downloaded properly. This makes the RAR files corrupt and then prompts the “checksum error” message during the process of RAR extraction.
• Interrupted transfer process: The existence of interruptions such as a sudden system shutdown, Windows restarts, power failure, and others while transferring RAR files from a computer to an external storage device or vice versa may lead to checksum error RAR.
• Insufficient disk space: If there is no more space for the Zip file to be extracted, you will receive the WinRAR checksum error.
• Unreliable third-party compression tools: The checksum error WinRAR could also happen if you extract the contents of WinRAR with unreliable compression programs.
• Virus/malware attacks: If there are virus/malware attacks in the RAR extraction process, the WinRAR checksum error might show up.
• Bad sectors on the storage drive: Bad sectors also trigger the checksum error.

In addition to checksum error WinRAR, you may encounter errors like CRC failed 7Zip and error 42125 Zip archive is corrupted while extracting files. Hence, you have to be cautious during the process of file extractions. For instance, you’d better use a reliable compression tool, utilize a powerful anti-virus program, and get enough free disk space before starting the extraction.

Solutions to WinRAR Checksum Error

Based on the above possible causes, this post would provide you with 6 available solutions to the checksum error WinRAR. You can try them one by one until the error is solved successfully.

Editor’s choice: It is strongly recommended to increase free disk space and check hard drive for bad sectors. By doing so, you can ensure that the checksum error WinRAR won’t occur because of insufficient disk space for the Zip file to be extracted or bad sectors on the storage media.

Solution 1: Use the Embedded Features in WinRAR

One of the WinRAR checksum error in the encrypted file fixes is to use the built-in features in WinRAR. Both the Keep broken files and Repair archive options of WinRAR can help you fix the WinRAR checksum error.

#1. The Keep Broken Files Option

The Keep broken files option in WinRAR allows you to extract your corrupted media. Once you tick the option, WinRAR will ignore the corruption in the file and help you extract the content from the zip folder.

Step 1: Right-click on the Zip or RAR compressed files and choose Extract Files from the context menu.

Step 2: Navigate to the Miscellaneous section and check the Keep broken files box.

Step 3: Choose an extraction location and then click OK to execute the changes. After a while, the file will be extracted to the selected location. However, it still shows the “checksum error”. You just need to ignore the error and open the file.

#2. The Repair Archive Option

The Repair archive option in WinRAR can solve the checksum error and fix the corrupt file. Once it is clicked, it will automatically execute the operation. Besides, it doesn’t require Internet connection. Nevertheless, this method can only fix minor RAR file corruption.

Here’s how to use the Repair archive option.

Старые версии WinRAR при вводе неправильного пароля перед распаковкой зашифрованных архивов не предлагали пользователям ввести его заново, и начинали извлечение файлов. Само собой, процесс заканчивался с ошибкой контрольной суммы, из которой было не ясно в чем дело – в неверно введенном пароле или в повреждении самого архива.

В последней версии WinRAR такой проблемы нет – установите ее и попробуйте распаковать проблемный архив снова. Если теперь прежний пароль не подходит, и разархивация не начинается, значит с архивом все в порядке. Осталось только вспомнить правильный пароль.

Если же распаковка вновь заканчивается диагностическим сообщением об ошибке контрольной суммы, значит часть или все файлы в архиве уже повреждены или повреждаются в процессе извлечения и сохранения на диск.

Протестируйте оперативную память и жесткие диски компьютера на потерю байтов информации, попробуйте извлечь файлы на другой носитель (другой HDD или флешку).

Если с «железом» проблем не обнаружится, откройте WinRAR, выберите поврежденный архив и нажмите кнопку «Исправить» на верхней панели.

В следующем окне нажмите ОК, чтобы начать восстановление.

P.S. Если поврежденный архив был скачан с интернета или скопирован с другого компьютера на флешку, в редких случаях помогает его повторная загрузка или копирование.

У меня есть защищенный паролем RAR-файл, который я создал с помощью WinRAR. Я хотел добавить другой файл к нему, однако способ, которым я это сделал, в конечном итоге повредил файл. Теперь, если я открою его и введу свой пароль, я получу это:

!   E:area51_record02-1.rar: Checksum error in the encrypted file E:area51_record02-1.rar. Corrupt file or wrong password.
!   E:area51_record02-1.rar: No files to extract

Итак, мой вопрос, есть ли способ отменить это? Ничто из того, что я сделал, не сработало. Извлечение его с сохранением битых файлов ничего не сделало. Ремонт WinRAR ничего не сделал. Я попытался использовать Recovery Toolbox for RAR, который ничего не делал, он просто очень медленно сканировал и не делал никакого прогресса.

Теперь точно, что я сделал. В моем файле RAR есть куча папок и файлов. Я открыл его, дважды щелкнув по нему, который не извлекается, а открывается внутри WinRAR. Затем я перетащил свой новый файл в это окно, и все оказалось в порядке, я увидел свой файл там и все. Когда я закрыл окно и попытался открыть его снова, я получил сообщение об ошибке, которое вы видите выше. У меня нет резервной копии RAR, поэтому я надеялся, что смогу изменить то, что сделал я.

There must be taken into account that WinRAR.exe (Windows GUI version) and Rar.exe (Windows console version) support two different types of encryption on creating a RAR archive:

1. file data encryption and
2. encryption of really all data including file names, sizes, attributes, comments and other blocks.

In first case a RAR archive file can be opened to get the list of file names, their original file sizes, their packed sizes, the last modification dates, etc. without the need of the password which means with decryption of any data.

In second case the password is even necessary to get the list of files and folders inside the archive file and all the other metadata.

There must be also taken into account if a RAR archive file is in RAR format 4 or in RAR format 5. The reason is explained below.

I created on Windows three RAR archive files using licensed Rar.exe.

1. The RAR file FileDataEncrypted.rar with just file data encrypted using the command line:

   "%ProgramFiles%WinRARRar.exe" a -cfg- -ep -idq -m5 -ma5 -mt1 -psecret FileDataEncrypted.rar "%ProgramFiles%WinRARRar.txt"
   

2. The RAR file FullyEncrypted.rar with all data encrypted using the command line:

   "%ProgramFiles%WinRARRar.exe" a -cfg- -ep -idq -m5 -ma5 -mt1 "-hpmore secret" FullyEncrypted.rar "%ProgramFiles%WinRARRar.txt"
   

3. The corrupted RAR file CorruptedArchive.rar with using first the command line:

   copy FileDataEncrypted.rar CorruptedArchive.rar
   

   Then I opened the file CorruptedArchive.rar in text editor UltraEdit in hex edit mode and modified 16 bytes at hexadecimal offset 2000 to hexadecimal value FF and saved the modified file.

See the text file Rar.txt for the meaning of the uses switches.

The three RAR archive files are all in RAR format 5 (switch -ma5).

Then I executed in the Windows command prompt window a batch file with the following command lines:

@echo off
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ -psecret FileDataEncrypted.rar
echo Exit code of FileDataEncrypted.rar extraction with correct password is: %ERRORLEVEL%
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ -pwrong FileDataEncrypted.rar
echo Exit code of FileDataEncrypted.rar extraction with wrong password is: %ERRORLEVEL%
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ "-hpmore secret" FullyEncrypted.rar
echo Exit code of FullyEncrypted.rar extraction with correct password is: %ERRORLEVEL%
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ "-hpwrong secret" FullyEncrypted.rar
echo Exit code of FullyEncrypted.rar extraction with wrong password is: %ERRORLEVEL%
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ -psecret CorruptedArchive.rar
echo Exit code of CorruptedArchive.rar extraction with correct password is: %ERRORLEVEL%
"%ProgramFiles%WinRARUnRAR.exe" x -idcdp -o+ -psecret CorruptedArchive.rar
echo Exit code of CorruptedArchive.rar extraction with wrong password is: %ERRORLEVEL%

The output was:

Extracting from FileDataEncrypted.rar

Extracting  Rar.txt                                                   OK
Exit code of FileDataEncrypted.rar extraction with correct password is: 0

Extracting from FileDataEncrypted.rar

Incorrect password for Rar.txt
Exit code of FileDataEncrypted.rar extraction with wrong password is: 11

Extracting from FullyEncrypted.rar

Extracting  Rar.txt                                                   OK
Exit code of FullyEncrypted.rar extraction with correct password is: 0

Incorrect password for FullyEncrypted.rar
Exit code of FullyEncrypted.rar extraction with wrong password is: 11

Extracting from CorruptedArchive.rar

Extracting  Rar.txt
Rar.txt              - checksum error
Exit code of CorruptedArchive.rar extraction with correct password is: 3

Extracting from CorruptedArchive.rar

Extracting  Rar.txt
Rar.txt              - checksum error
Exit code of CorruptedArchive.rar extraction with wrong password is: 3

The text file Rar.txt explains the exit values at bottom with:

   Code   Description   

    0     Successful operation.
    1     Non fatal error(s) occurred.
    2     A fatal error occurred.
    3     Invalid checksum. Data is damaged.
    4     Attempt to modify an archive locked by 'k' command.
    5     Write error.
    6     File open error.
    7     Wrong command line option.
    8     Not enough memory.
    9     File create error
   10     No files matching the specified mask and options were found.
   11     Wrong password.
   12     Read error.
  255     User stopped the process.

The usage of the wrong password on the command line for the two valid RAR archives results in an output of the error message Incorrect password for ... of the archived file inside the RAR archive file (first case) or the entire RAR archive file (second case) and an exit with the value 11.

The error message is always checksum error and the exit code is always 3 on RAR archive file being corrupted independent on using correct or wrong password.

The RAR archive format 5 makes it possible for the RAR extraction code to determine if the password for decryption is wrong or the archive file itself is corrupted.

I created next the three RAR archive files once again, but using the switch -ma4 instead of -ma5 to create two valid and a corrupted RAR archive files in RAR archive format 4.

Next I executed the same batch file for extraction as before. The output was this time:

Extracting from FileDataEncrypted.rar

Extracting  Rar.txt                                                   OK
Exit code of FileDataEncrypted.rar extraction with correct password is: 0

Extracting from FileDataEncrypted.rar

Extracting  Rar.txt
Checksum error in the encrypted file Rar.txt. Corrupt file or wrong password.
Exit code of FileDataEncrypted.rar extraction with wrong password is: 3

Extracting from FullyEncrypted.rar

Extracting  Rar.txt                                                   OK
Exit code of FullyEncrypted.rar extraction with correct password is: 0

Checksum error in the encrypted file FullyEncrypted.rar. Corrupt file or wrong password.
No files to extract
Exit code of FullyEncrypted.rar extraction with wrong password is: 3

Extracting from CorruptedArchive.rar

Extracting  Rar.txt
Checksum error in the encrypted file Rar.txt. Corrupt file or wrong password.
Exit code of CorruptedArchive.rar extraction with correct password is: 3

Extracting from CorruptedArchive.rar

Extracting  Rar.txt
Checksum error in the encrypted file Rar.txt. Corrupt file or wrong password.
Exit code of CorruptedArchive.rar extraction with wrong password is: 3

It can be seen on the error messages as well as on always same exit code 3 that it is not possible for the extraction code to determine if the password is wrong or there is a corruption of the archive file data on RAR archive file being in format 4.

The currently latest UnRAR C++ source code can be downloaded from the WinRAR and RAR archiver addons page as it is freeware, see license.txt in the source archive file. There are also UnRAR binaries available for download many platforms on same page.

UnRAR and 7-Zip used on Ubuntu output the same error message as UnRAR.exe and of course also Rar.exe on Windows on extraction of a RAR archive file in RAR format 4 being either corrupted or on which the wrong password is entered by the user. It is not possible to find out the cause of the checksum error as it can be seen above. UnRAR and 7-Zip are compiled with using the UnRAR source code.

The Ubuntu documentation page for File Roller in chapter Supported Formats in the section Not installed by default in Ubuntu the information that format RAR is supported only by File Roller with using unrar (non-free) or unrar-free package to extract .rar archives. So it depends on how old is the extra installed unrar package for extraction of RAR archive file and how new is the RAR archive file.

The question in title is:

Can Archive Manager distinguish between wrong password and corrupted file?

The answer is:

Yes, if the used UnRAR code is up-to-date and the RAR archive file is in RAR format 5.
No, if the used UnRAR code is pretty old or the RAR archive file is in RAR format 4.
