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.

Решение ошибки контрольной суммы при распаковке файла RAR

Способ 1: Обновление версии архиватора

Рассматриваемая ошибка возникает в том числе из-за несовместимости алгоритмов разных вариантов ВинРАР: например, архив, созданный в пятой версии, получится распаковать только ею, так как в более старых отсутствует требуемая функция. Поэтому первое, что необходимо сделать при столкновении с подобной проблемой – убедиться, что установлена самая свежая версия приложения.

Способ 2: Использование функции восстановления

В WinRAR практически с момента появления присутствовала возможность, известная как «Лечение»: если при распаковке файлов будет обнаружено, что они повреждены, задействование этой опции поможет вернуть архиву работоспособность, но только при условии, что в сжатых данных есть код для восстановления.

1. Откройте ВинРАР и с помощью встроенного в программу файлового менеджера найдите требуемый документ.
2. Выделите его, один раз нажав левую кнопку мыши, затем на панели инструментов воспользуйтесь элементом «Исправить».
3. Утилита восстановления автоматически подбирает оптимальные параметры, поэтому рекомендуем оставить их как есть и нажать «ОК».

Эта функция позволяет устранить проблему, но только при условии, что информация для восстановления присутствует в архиве.

Способ 3: Проверка ввода пароля

Если рассматриваемая ошибка появляется при попытках распаковать запароленный архив, причина элементарна – пользователь вводит неверные данные. Если сложно ориентироваться с закрытыми символами, отметьте опцию «Отображать пароль при вводе», после чего они будут видны.

Но если ключ верный, данные, скорее всего, действительно повреждены – воспользуйтесь соответствующими способами для устранения проблемы.

Способ 4: Загрузка архива заново

Иногда ни попытки восстановления, ни ввод корректного пароля не позволяют устранить ошибку. В такой ситуации единственной действенной мерой будет новая загрузка проблемного архива из интернета или копирование с оригинального источника, так как, скорее всего, данные действительно безвозвратно повреждены. В дальнейшем во избежание подобного придерживайтесь следующих советов:

• не доверяйте скачивание объёмных (размером 500 Мб и больше) запакованных файлов встроенному загрузчику веб-обозревателя, если соединение с сервером или интернетом нестабильно – воспользуйтесь одним из сторонних менеджеров загрузок вроде Download Master;
• для копирования или переноса данных используйте только заведомо рабочие носители, в процессе работы с ними не нагружайте компьютер трудными задачами.

При соблюдении этих рекомендаций вероятность столкновения с рассматриваемой ошибкой стремится к нулю.

Способ 5: Устранение проблем с ОЗУ и накопителем

Порой ошибка контрольной суммы может быть симптомом неполадок с рабочим компьютером, а именно, его накопителем или оперативной памятью, поскольку в процессе разархивации они нагружаются больше всего. Методика проверки очень простая – попробуйте распаковать другой, заведомо рабочий архив, который находится на том же диске, что и проблемный. Если сбой наблюдается, это верный признак аппаратных поломок. Протестируйте память, жёсткий/твердотельный диск и при обнаружении проблем замените устройства.

Начиная с самых первых поколений персональных компьютеров, проблема дефицита дискового пространства была одной из самых актуальных. Над её решением работали лучшие умы отрасли, и одним из эффективных способов решения, как вы уже догадались, оказалось использование архиваторов. Как оказалось, степень сжатия файла сильно зависит от его типа. Например, при упаковке текстов размер файла уменьшается в разы, а для большого текста – даже на порядок. Исполняемые файлы сжимаются хуже, а некоторые виды файлов, изначально созданных с использованием упаковщиков, практически не сжимаются.

Так или иначе, но архиваторы и поныне используются повсеместно – как правило, пакеты программ для установки поставляются именно в виде архивов, в том числе самораспаковывающихся. Но иногда при распаковке сжатых файлов пользователи сталкиваются с ошибкой несовпадения контрольной суммы, в результате чего очень нужный файл извлечь из архива не удаётся. Сегодня мы рассмотрим основные причины возникновения ошибки CRC и способы её устранения.

Причины появления ошибки

Для начала стоит вкратце ознакомиться с азами теории сжатия. Алгоритмы компрессии данных основываются на поиске одинаковых длинных фрагментов и их кодировании менее ёмким кодом. Даже в этом тексте таких фрагментов предостаточно. Например, двухбуквенных повторений. Но программы-архиваторы ищут более длинные повторяющиеся последовательности, так что коэффициент сжатия в итоге получается очень даже существенным.

При создании архива в него, кроме закодированной последовательности, включается таблица кодов и некоторые другие данные, в том числе контрольная сумма архива. Это число, хранимое в шестнадцатеричном виде, представляющее собой значение, рассчитанное на основании основной последовательности данных с применением специальных математических алгоритмов. Оно является уникальным именно для такой последовательности данных. Внесение любого изменения, даже однобитного, приведёт к кардинально другой контрольной сумме.

Особенность контрольной суммы (её принято называть хэш-суммой) заключается в том, что по ней невозможно восстановить исходную последовательность данных, но она является идеальным инструментом для определения подлинности полученного файла. Итак, в сам архив вносится контрольная сумма, она же вычисляется при разархивировании файла. Если хэш-суммы не совпадают, это говорит о том, что архив изменён уже после его создания.

В подобных случаях при распаковке файлов архиватор выдаёт соответствующее сообщение об ошибке несовпадения контрольной суммы, прекращая дальнейшую работу.

Итак, если при распаковке архива RAR вы получили сообщение об ошибке контрольной суммы, это может означать следующее:

• сам архив создан некорректно – например, если программа-архиватор, создавшая архив, заражена вирусом;
• используемый вами архиватор для распаковки архивов повреждён или работает со сбоями;
• иногда причиной становится несовпадение версий архиватора;
• ещё одной причиной появления ошибки может быть наличие кириллических символов при указании каталога распаковки;
• ошибка несовпадения CRC-кода может возникать и вследствие проблем с железом: при наличии сбойных секторов на накопителе или если модуль ОЗУ работает со сбоями.

Рассмотрим основные методы устранения данной ошибки.

Способы решения проблемы

В большинстве случаев виновником возникновения ошибки контрольной суммы в заархивированном файле является сам архив, про который в таких случаях говорят «битый».

Проверка источника данных

Если вы скачали файл с оптического диска – возможно, он получил повреждения из-за дефектов DVD-носителя. Проверьте, нет ли на нём царапин, сколов, потёртостей или трещин. При их наличии стоит поискать исходный файл в другом месте.

Если архив загружен из сети, есть вероятность, что файл получил повреждения в процессе скачивания – такое иногда случается, пакеты теряются. Можно попытаться скачать его повторно, но если ошибка не исчезнет, возможно, битый архив уже лежит на сервере. Тогда имеет смысл поискать этот же пакет в другом месте.

Словом, первое, что нужно сделать, получив данную ошибку при распаковке, – скачать файл с нескольких источников.

Исключение кириллицы из полного пути установки

Дистрибутивы программ далеко не всегда пишут программисты высокой квалификации. В силу этого нередки случаи, когда пакет содержит компоненты, которые не адаптированы под некоторые языки, в частности – кириллицу. И тогда такие дистрибутивы при распаковке могут генерировать ошибку контрольной суммы, касается ли это 7ZIP или WINRAR.

Если тот архиватор, которым вы пользуетесь, предлагает распаковать архив с документами в папку «Документы», или же вы сознательно разархивируете дистрибутивы программ в каталог «Софт», вам стоит попробовать использовать имена, не содержащие русских букв, – например, Docs или Soft.

То есть при распаковке внимательно следите за тем, в какую папку архиватор предлагает распаковать архив, причём кириллица может быть в любом участке пути.

Распаковщики, если речь идёт о старых версиях Windows, могут выдавать ошибку и из-за того, что кириллица присутствует в имени учётной записи. Изменить имя можно через «параметры», но если это для вас неприемлемо, можно создать нового пользователя с английским написанием его имени – это должно решить проблему.

Обновление версии архиватора

Операционная система Windows имеет собственные средства распаковки наиболее распространённых форматов архивов – zip, arj, rar, 7z, однако их функционал недостаточен по сравнению со специализированными пакетами.

Если во время распаковки архива произошла ошибка несовпадения контрольной суммы, стоит воспользоваться именно такими программами, например, WinRAR или упоминавшийся уже 7ZIP. Любая из них может справиться практически с любым типом архива. Скачивать нужно с официального сайта – это гарантирует отсутствие таких проблем, как заражение вирусом, чем грешат многие файлообменники. После установки архиватора нужно перегрузить компьютер и приступить к распаковке файла, вызвавшего ошибку.

Если и при использовании архиватора ошибка CRC не исчезла, вполне возможно, что это из-за того, что вы пользуетесь устаревшей программой. Не поленитесь посетить официальный сайт разработчика на предмет скачивания самой последней версии инсталляционного пакета – обычно это устраняет все возможные проблемы.

До сих пор мы рассматривали только программные способы устранения ошибки контрольной суммы, но она может возникнуть и по аппаратным причинам. В частности, такое нередко случается на компьютерах с разогнанным процессором или оперативкой. Оверклокинг хорош для выполнения ресурсоёмких задач, но в случае с работой архиватора он может вместо пользы принести вред, инициировав сбой при распаковке архива, что в итоге выльется в ошибку CRC.

Решение проблемы – отключение разгона. Проще всего это сделать, выполнив сброс BIOS до заводских настроек, после чего можно проверить работоспособность архиватора.

Устранение неполадок с диском компьютера

Более вероятным виновником появления ошибки несовпадения контрольной суммы при установке программ является наличие сбойных секторов на диске. Если ваш HDD возрастной, то стоит проверить его специализированной утилитой (можно и встроенными средствами Windows). С твердотельными накопителями такая неприятность случается чаще – в силу ограничений по циклам записи/чтения, свойственным для SSD.

Если ячейка памяти нечитабельна, очевидно, что при считывании файла его целостность будет нарушена, а значит, подсчёт контрольной суммы выдаст несовпадение со значением, записанным в самом архиве.

В обоих случаях нужно просканировать диск с опцией исправления ошибок, после чего снова скачать архив и распаковать его.

Как правило, в 95% случаев проблема кроется именно в битом архиве, поэтому с такой же вероятностью вам не понадобятся все изложенные способы решения проблемы несовпадения контрольной суммы, кроме первого.

Ошибка контрольной суммы (CRC) в WinRAR

Бывает качаешь целый час большой архив с какого-нибудь сайта, пытаешься открыть его в WinRAR и получаешь сообщение: «ошибка контрольной суммы» или «ошибка CRC сжатых данных». Что делать и почему такое происходит?

Данная ошибка возникает, если во время загрузки архива были потери пакетов, то есть он скачался вроде бы полностью, но несколько байтов информации в нем не хватает или они отличаются от того, что должно быть. Потеря пакетов – частое явление при нестабильном интернет-соединении. Чем больше размер загружаемого архива и дольше происходит его скачивание – тем больше вероятность возникновения подобной ошибки.

Как решить проблему?

Есть 2 способа, с помощью которых можно исправить ошибку контрольной суммы.

Способ 1

Самое элементарное – скачать архив заново. Для скачивания лучше использовать специальную программу, загрузчик файлов, например, Download Master.

Способ 2

Можно попытаться восстановить архив с помощью встроенной функции WinRAR. В архиве может содержаться информация для восстановления, которая будет использована архиватором для «оживления» поврежденного архива.

Запустите WinRAR и через его интерфейс найдите проблемный архив. Щелкните на нем правой кнопкой мыши и выберите «восстановить архив(ы)».

В некоторых случаях может появиться окно, предлагающее указать, какой формат у архива, который вы хотите восстановить. Укажите правильный формат файла (его расширение) и нажмите «ОК».

Если повезет, архив будет восстановлен.

*если ошибка CRC у вас возникает постоянно при открытии любых архивов на вашем компьютере, рекомендуем проверить оперативную память и жесткие диски на предмет потери данных, с помощью такой программы, как AIDA или обратившись к специалистам.
