Как запустить проверку диска на ошибки в командной строке

Вывод на экран отчета о состоянии диска в форме, зависящей от используемой файловой системы. Команда chkdsk также составляет список ошибок на диске и исправляет их. Выполненная без параметров команда chkdsk выводит информацию о состоянии текущего диска.

Синтаксис

chkdsk [том:][[путь] имя_файла]  [/f]  [ /v]  [/r]  [/x]  [/i]  [/c]  [ /l[:размер]]

Параметры

том:

Указывает букву диска (с последующим двоеточием), точку подключения или имя тома.

[путь] имя_файла

Задает местонахождение и имя файла или имена множества файлов, для которых команда chkdsk проверит степень фрагментации. Для задания нескольких файлов можно использовать подстановочные знаки (* и ?).

/f

Задает исправление ошибок на диске. Диск должен быть заблокирован. Если диск не заблокирован командой chkdsk, отображается запрос на проверку диска при следующей перезагрузке компьютера.

/v

Выводит на экран имена проверяемых файлов и каталогов.

/r

Обнаруживает поврежденные сектора и восстанавливает ту часть данных, которая еще может быть прочитана. Диск должен быть заблокирован.

/x

Используйте только с файловой системой NTFS. При необходимости инициирует операцию отключения тома в качестве первого действия. Все открытые дескрипторы диска будут неверны. Параметр /x включает также функциональные возможности параметра /f.

/i

Используйте только с файловой системой NTFS. Выполняет менее тщательную проверку записей индекса, что уменьшает время, необходимое для работы команды chkdsk.

/c

Используйте только с файловой системой NTFS. Пропускает проверку циклов в структуре папок, что уменьшает время, необходимое для работы командыchkdsk.

/l[:размер]

Используйте только с файловой системой NTFS. Устанавливает указанный размер журнала. Если размер не указан, параметр /l выводит текущий размер.

/?

Отображение справки в командной строке.

Заметки

• Выполнение команды chkdsk

  Чтобы выполнить команду chkdsk для жестких дисков, необходимо быть членом группы администраторов.

• Проверка заблокированных дисков при перезагрузке

  Если требуется исправить ошибки на диске с помощью команды chkdsk, нельзя открывать файлы на этом диске. В противном случае выводится следующее сообщение о ошибке:

  Невозможно выполнить команду Chkdsk, так как указанный том используется другим процессом. Следует ли выполнить проверку этого тома при следующей перезагрузке системы? [Y(да)/N(нет)]

  Если пользователь выберет эту возможность, команда chkdsk проверит диск и автоматически исправит ошибки при перезагрузке компьютера. Если проверяемый раздел диска является загрузочным, команда chkdskавтоматически перезагрузит компьютер после проверки этого диска.

• Отчет об ошибках

  Команда chkdsk выполняет проверку дискового пространства и его использования для файловых систем таблица размещения файлов (FAT) и NTFS. Команда Chkdsk позволяет получить отчет о состоянии со сведениями по каждой файловой системе. Отчет о состоянии диска включает перечень найденных ошибок. Если команда chkdsk запущена без параметра /f в активном разделе, может быть получено сообщение о наличии серьезных ошибок, так как диск нельзя заблокировать. Для поиска ошибок командуchkdsk нужно запускать время от времени на каждом диске.

• Исправление ошибок

  Если указан параметр командной строки /f, программа chkdsk исправляет ошибки на диске. При работе chkdsk должна обеспечиваться возможность блокирования диска для исправления ошибок. Поскольку при исправлении ошибок обычно изменяется таблица размещения файлов и иногда происходит потеря данных, программа chkdsk запрашивает подтверждение в следующем виде:

  Потерянных кластеров: 10; цепочек: 3.

  Преобразовать потерянные цепочки кластеров в файлы [Y(да)/N(нет)]?

  Если ввести Y, Windows сохраняет каждую потерянную цепочку в корневом каталоге как файл с именем формата Filennnn.chk. После завершения выполнения chkdsk можно проверить эти файлы на наличие нужных сведений. Если ввести N, Windows исправляет ошибки на диске без сохранения данных из потерянных блоков.

  Если параметр командной строки /f не используется, программа chkdskтолько выдает сообщение о наличие ошибок в файле, но не исправляет их.

  Если команда chkdsk /f запущена на диске большого объема (например 70 Гб) или диск содержит большое количество файлов (например несколько миллионов), для завершения работы программы chkdsk может потребоваться очень много времени (возможно несколько дней). В течение всего этого времени компьютер будет недоступен для пользователей, так как chkdsk не возвращает управления до завершения работы.

• Проверка дисков с файловой системой FAT

  Система Windows выводит отчет программы chkdsk о состоянии диска с файловой системой FAT в следующем формате:

  Серийный номер тома: B1AF-AFBF

  72214528 байт всего на диске

  73728 байт в 3 скрытых файлах

  30720 байт в 12 каталогах

  11493376 байт в 386 пользовательских файлах

  61440 байт в поврежденных секторах

  60555264 байт доступно на диске

  2048 байт в каждом кластере

  Всего кластеров на диске: 35261.

  29568 кластеров на диске

• Проверка дисков с файловой системой NTFS

  Система Windows выводит отчет программы chkdsk о состоянии диска с файловой системой NTFS в следующем формате:

  Тип файловой системы: NTFS.

  Проверка файлов...

  Проверка файлов завершена.

  Проверка индексов...

  Проверка индесков завершена.

  Проверка описателей защиты...

  Проверка описателей защиты завершена.

  12372 Кбайт всего на диске.

  3 Кбайт в 1 пользовательских файлах.

  2 КБ в 1 индексах.

  4217 КБ используется системой.

  8150 Кбайт свободно на диске.

  Размер кластера: 512 байт.

  Всего кластеров на диске: 24745.

  16301 кластеров на диске.
• Использование chkdsk с открытыми файлами

  Если указан параметр /f, команда chkdsk выводит сообщение об ошибке, если на диске найдены открытые файлы. Если же параметр /f не указан и на диске найдены открытые файлы, chkdsk может выводить сообщения о потерянных блоках на диске. Это произойдет в случае, когда открытые файлы еще не записаны в таблице размещения файлов. Если программа chkdsk сообщает о большом количестве потерянных блоков дискового пространства, должна быть рассмотрена возможность ремонта диска.

• Обнаружение физических ошибок диска

  Используйте параметр командной строки /r для обнаружения физических ошибок диска в файловой системе. Для получения сведений о восстановлении физически поврежденных файлов с помощью команды recover щелкните ссылку.

• Отчет о поврежденных секторах диска

  Испорченные сектора, о которых сообщает команда chkdsk, были маркированы при первом форматировании диска. Такие сектора не представляют опасности.

• Общие сведения о кодах завершения программы

  В следующей таблице перечислены коды завершения, которые могут содержатся в отчете программы chkdsk после окончания ее выполнения.

  Код выхода	Описание
  0	Не найдено ни одной ошибки.
  1	Ошибки найдены и исправлены.
  2	Была выполнена очистка диска, например удалены ненужные файлы, или очистка не была выполнена из-за отсутствия ключа /f.
  3	Диск не может быть проверен, ошибки не могут быть исправлены или ошибки не были исправлены, так как не был задан ключ /f.

• Команда chkdsk с другими параметрами доступна в консоли восстановления.

Примеры

Если требуется проверить диск в дисководе D и исправить все обнаруженные ошибки в Windows, введите следующую команду:

chkdsk d: /f

Если обнаружена ошибка, выполнение программы сhkdsk приостанавливается и выводятся соответствующие сообщения. По окончании выполнения команды chkdskна экран выводится отчет, содержащий сведения о текущем состоянии диска. До завершения работы chkdsk нельзя открывать какие-либо файлы на указанном диске.

Чтобы проверить фрагментацию всех файлов в текущем каталоге на диске с файловой системой FAT, введите следующую команду:

chkdsk *.*

Chkdsk выведет отчет о состоянии диска, а затем список фрагментированных файлов, удовлетворяющих шаблону команды.

chkdsk	Reference article for the chkdsk command, which checks the file system and file system metadata of a volume for logical and physical errors.	reference	62912a3c-d2cc-4ef6-9679-43709a286035	jasongerend	alalve	11/22/2022

Checks the file system and file system metadata of a volume for logical and physical errors. If used without parameters, chkdsk displays only the status of the volume and does not fix any errors. If used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.

[!IMPORTANT]
Membership in the local Administrators group, or equivalent, is the minimum required to run chkdsk. To open a command prompt window as an administrator, right-click Command prompt in the Start menu, and then click Run as administrator.

[!IMPORTANT]
Interrupting chkdsk is not recommended. However, canceling or interrupting chkdsk should not leave the volume any more corrupt than it was before chkdsk was run. Running chkdsk again checks and should repair any remaining corruption on the volume.

[!NOTE]
Chkdsk can be used only for local disks. The command cannot be used with a local drive letter that has been redirected over the network.

Syntax

chkdsk [<volume>[[<path>]<filename>]] [/f] [/v] [/r] [/x] [/i] [/c] [/l[:<size>]] [/b]

Parameters

Parameter	Description
<volume>	Specifies the drive letter (followed by a colon), mount point, or volume name.
[ [<path>]<filename>	Use with file allocation table (FAT) and FAT32 only. Specifies the location and name of a file or set of files that you want chkdsk to check for fragmentation. You can use the ? and * wildcard characters to specify multiple files.
/f	Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.
/v	Displays the name of each file in every directory as the disk is checked.
/r	Locates bad sectors and recovers readable information. The disk must be locked. /r includes the functionality of /f, with the additional analysis of physical disk errors.
/x	Forces the volume to dismount first, if necessary. All open handles to the drive are invalidated. /x also includes the functionality of /f.
/i	Use with NTFS only. Performs a less vigorous check of index entries, which reduces the amount of time required to run chkdsk.
/c	Use with NTFS only. Does not check cycles within the folder structure, which reduces the amount of time required to run chkdsk.
/l[:<size>]	Use with NTFS only. Changes the log file size to the size you type. If you omit the size parameter, /l displays the current size.
/b	Use with NTFS only. Clears the list of bad clusters on the volume and rescans all allocated and free clusters for errors. /b includes the functionality of /r. Use this parameter after imaging a volume to a new hard disk drive.
/scan	Use with NTFS only. Runs an online scan on the volume.
/forceofflinefix	Use with NTFS only (must be used with /scan). Bypass all online repair; all defects found are queued for offline repair (for example, chkdsk /spotfix).
/perf	Use with NTFS only (must be used with /scan). Uses more system resources to complete a scan as fast as possible. This may have a negative performance impact on other tasks running on the system.
/spotfix	Use with NTFS only. Runs spot fixing on the volume.
/sdcleanup	Use with NTFS only. Garbage collect unneeded security descriptor data (implies /f).
/offlinescanandfix	Runs an offline scan and fix on the volume.
/freeorphanedchains	Use with FAT/FAT32/exFAT only. Frees any orphaned cluster chains instead of recovering their contents.
/markclean	Use with FAT/FAT32/exFAT only. Marks the volume clean if no corruption was detected, even if /f was not specified.
/?	Displays help at the command prompt.

Remarks

• The /i or /c switch reduces the amount of time required to run chkdsk by skipping certain volume checks.

• If you want chkdsk to correct disk errors, you can’t have open files on the drive. If files are open, the following error message appears:

  Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
  

• If you choose to check the drive the next time you restart the computer, chkdsk checks the drive and corrects errors automatically when you restart the computer. If the drive partition is a boot partition, chkdsk automatically restarts the computer after it checks the drive.

• You can also use the chkntfs /c command to schedule the volume to be checked the next time the computer is restarted. Use the fsutil dirty set command to set the volume’s dirty bit (indicating corruption), so that Windows runs chkdsk when the computer is restarted.

• You should use chkdsk occasionally on FAT and NTFS file systems to check for disk errors. Chkdsk examines disk space and disk use and provides a status report specific to each file system. The status report shows errors found in the file system. If you run chkdsk without the /f parameter on an active partition, it might report spurious errors because it cannot lock the drive.

• Chkdsk corrects logical disk errors only if you specify the /f parameter. Chkdsk must be able to lock the drive to correct errors.

  Because repairs on FAT file systems usually change a disk’s file allocation table and sometimes cause a loss of data, chkdsk might display a confirmation message similar to the following:

  10 lost allocation units found in 3 chains.
  Convert lost chains to files?
  

  • If you press Y, Windows saves each lost chain in the root directory as a file with a name in the format File<nnnn>.chk. When chkdsk finishes, you can check these files to see if they contain any data you need.

  • If you press N, Windows fixes the disk, but it does not save the contents of the lost allocation units.

• If you don’t use the /f parameter, chkdsk displays a message that the file needs to be fixed, but it does not fix any errors.

• If you use chkdsk /f* on a very large disk or a disk with a very large number of files (for example, millions of files), chkdsk /f might take a long time to complete.

• Use the /r parameter to find physical disk errors in the file system and attempt to recover data from any affected disk sectors.

• If you specify the /f parameter, chkdsk displays an error message if there are open files on the disk. If you do not specify the /f parameter and open files exist, chkdsk might report lost allocation units on the disk. This could happen if open files have not yet been recorded in the file allocation table. If chkdsk reports the loss of a large number of allocation units, consider repairing the disk.

• Because the Shadow Copies for Shared Folders source volume cannot be locked while Shadow Copies for Shared Folders is enabled, running chkdsk against the source volume might report false errors or cause chkdsk to unexpectedly quit. You can, however, check shadow copies for errors by running chkdsk in Read-only mode (without parameters) to check the Shadow Copies for Shared Folders storage volume.

• The chkdsk command, with different parameters, is available from the Recovery Console.

• On servers that are infrequently restarted, you may want to use the chkntfs or the fsutil dirty query commands to determine whether the volume’s dirty bit is already set before running chkdsk.

Understanding exit codes

The following table lists the exit codes that chkdsk reports after it has finished.

Exit code	Description
0	No errors were found.
1	Errors were found and fixed.
2	Performed disk cleanup (such as garbage collection) or did not perform cleanup because /f was not specified.
3	Could not check the disk, errors could not be fixed, or errors were not fixed because /f was not specified.

Examples

To check the disk in drive D and have Windows fix errors, type:

If it encounters errors, chkdsk pauses and displays messages. Chkdsk finishes by displaying a report that lists the status of the disk. You cannot open any files on the specified drive until chkdsk finishes.

To check all files on a FAT disk in the current directory for noncontiguous blocks, type:

Chkdsk displays a status report, and then lists the files that match the file specifications that have noncontiguous blocks.

Viewing chkdsk logs

There are two methods that can be used to retrieve chkdsk log file(s) in Windows. View the methods described below:

Event Viewer

To view logs with Event Viewer, navigate to the following:

1. Start > Control Panel > Administrative Tools > Event Viewer.

   Alternatively, press Win + R keys to bring up the run dialog box, type eventvwr.msc, and select OK.

2. Expand Windows Logs > right-click on Application > select Filter Current Log.

3. Within the Filter Current Log window, navigate to Event sources drop-down menu, select Chkdsk and Wininit.

4. Click OK to finish filtering for these two sources.

PowerShell

There are two source types when retrieving logs in PowerShell, chkdsk and wininit. Run one of the two commands in PowerShell to view the most current chkdsk log:

get-winevent -FilterHashTable @{logname="Application"} | ?{$_.providername -match "chkdsk"} | fl timecreated, message

get-winevent -FilterHashTable @{logname="Application"} | ?{$_.providername -match "wininit"} | fl timecreated, message

To export the log to a specific location, the following can be added to the end of the command | out-file "$env:userprofilelocationfilename.txt". Example:

get-winevent -FilterHashTable @{logname="Application"} | ?{$_.providername -match "chkdsk"} | fl timecreated, message | out-file "C:UsersAdministratorDesktopChkdsk_Log.txt"

get-winevent -FilterHashTable @{logname="Application"} | ?{$_.providername -match "wininit"} | fl timecreated, message | out-file "C:UsersAdministratorDesktopWininit_Log.txt"

Команда CHKDSK предназначена для проверки и устранения логических ошибок на жестком диске. Ниже мы рассмотрим особенности её работы и другие функции утилиты.

Содержание

1. Проверка жесткого диска в работающей Windows
2. Проверка диска из командной строки
3. Команды для работы с CHKDSK в командной строке
4. Восстановление информации с проблемного жесткого диска

Команда CHKDSK является встроенной утилитой, основная функция которой заключается в проверке и исправлении ошибок жесткого диска. Помимо этого, при помощи CHKDSK можно быстро находить и исправлять поврежденные сектора, а также ошибки в файловой системе накопителя.

Таким образом, CHKDSK – важная утилита, позволяющая продлить строк службы жесткого диска, а также увеличить скорость его работы, поэтому абсолютно каждый пользователь ОС Windows должен уметь пользоваться и проверять свои носители встроенными средствами. Ниже будет представлено несколько способов проверки дисков из работающей ОС и командной строки.

Проверка жесткого диска в работающей Windows

Для проверки логических разделов жесткого диска при помощи CHKDSK в работающей Windows необходимо:

Шаг 1. Открыть каталог «Этот компьютер», нажать правой кнопкой мыши по необходимому логическому разделу и выбрать пункт «Свойства».

Шаг 2. В открывшемся окне перейти во вкладку «Сервис» и выбрать пункт «Проверить».

Шаг 3. Подтверждаем проверку диска и после ее завершения нажимаем по кнопке «Показать подробности».

Шаг 4. Вся информация и результаты проверки диска будут доступны в графе «Сведения».

Проверка диска из командной строки

В некоторых ситуациях пользователю может понадобиться запуск утилиты CHKDSK из командной строки. Такая возможность позволит проверить и восстановить диск в том случае, если система не запускается и графический интерфейс Windows остается недоступным.

Чтобы запустить командную строку из среды восстановления ОС, необходимо:

Шаг 1. Воспользоваться установочным диском или загрузочной флешкой Windows и после окна выбора языка нажать по пункту «Восстановление системы». Перейдя в среду восстановления, следует нажать по пункту «Поиск и устранение неисправностей».

Шаг 2. На следующем окне следует выбрать пункт «Дополнительные параметры», после чего можно обнаружить кнопку «Командная строка».

Также всегда остается возможность запустить утилиту проверки дисков через командную строку из работающей системы. Важно! Для использования полного потенциала CHKDSK следует производить запуск командной строки только с правами администратора. В ином случае утилита CHKDSK проведет проверку без устранения выявленных неполадок.

Запустить командную строку или Windows PowerShell от имени администратора можно, нажав правой кнопкой мыши по кнопке «Пуск» и выбрав пункт «Командная строка(администратор)».

Команды для работы с CHKDSK в командной строке

Находясь в командной строке, можно провести быструю проверку жесткого диска (аналогичная проверка была описана в начале) без перезагрузки системы. Для этого достаточно ввести команду «CHKDSK» и подтвердить действие кнопкой Enter.

Для проверки диска и исправления логических ошибок на нем необходимо воспользоваться командой «chkdsk C: /F /R», где С – имя необходимого диска.

Для подтверждения проверки диска после перезагрузки необходимо нажать клавишу «Y».

Помимо полного анализа и по возможности исправления поврежденных секторов, утилита может выполнять проверку и решение ошибок только файловой системы. Для этого следует воспользоваться командой «chkdsk C: /F» и подтвердить действие «Y».

С полным списком и описанием возможностей утилиты можно ознакомится, введя команду «chkdsk /?».

Стоит отметить, что проблемы с диском могут быть вызваны не только программными ошибками, но и физическим износом, механическими повреждениями поверхности и другими факторами, которые невозможно исправить при помощи встроенной утилиты CHKDSK.

Чтобы получить полную картину о состоянии носителя, можно воспользоваться бесплатной программой для проверки дисков Victoria. Узнать о том, как пользоваться, исправлять и проводить диагностику HDD с помощью Victoria Вы сможете в статье: «Используем программу Victoria для тестирования и исправления жесткого диска»

Восстановление информации с проблемного жесткого диска

Проблемы с жестким диском – всегда большая угроза для важной информации и документов, хранящихся на компьютере. Чтобы быть готовым к любым обстоятельствам, рекомендуем всегда иметь под рукой специальную программу для эффективного восстановления файлов RS Partition Recovery. Данная утилита поможет восстановить всю утерянную информацию даже в самых сложных случаях.

При помощи RS Partition Recovery можно восстанавливать:

• Случайно удаленные файлы и документы.
• Отформатированные фотографии и медиафайлы.
• Данные, удаленные вирусами.
• Информацию, которая была утеряна при изменении файловой системы и структуры диска.

FAQs About CHKDSK /F /R That You May Be Interested In

You may encounter CHKDSK related problems; what to do then? Here are the common issues of CHKDSK errors; read on to figure out the solutions.

1. Is CHKDSK R safe?

It’s safe to run the CHKDSK /R command under normal circumstances as long as you’re using the syntax properly. There are different parameters with CHKDSK; you can check the CHKDSK parameters and choose the one that suits your problem to fix disk errors.

2. How long does chkdsk /f /r take?

It depends.

• chkdsk -f should take under an hour on that hard drive.
• chkdsk -r will take some time. It could take over an hour, maybe two, three, or more, depending on your partitioning.

You can interrupt the scan, but not recommended. Canceling or interrupting CHKDSK should not leave the volume any more corrupt than it was before CHKDSK was run. You can start it again, and it will check and repair any remaining corruption on the volume.

3. What to do when CHKDSK is stuck or frozen?

• Restart your computer.
• Press Esc or Enter to stop chkdsk from running.
• Run the Disk Cleanup utility to clear out junk files.
• Open an elevated CMD, type sfc /scannow, and press Enter to run the System File Checker. 
• Restart and exit chkdsk again during the startup by pressing Esc or Enter.
• Open CMD as admin, type Dism /Online /Cleanup-Image /RestoreHealth, and press Enter to repair the Windows image.
• Run CHKDSK again.

The scan should be able to run to completion this time.

4. CHKDSK /F /R VS CHKDSK /R /F on Windows

What’s the difference between CHKDSK /F /R and CHKDSK /R /F commands on Windows computer?

This is no much difference between chkdsk /f /r and chkdsk /r /f. The only difference is the sequence of two parameters /f and /r. /f means to fix errors on target disk and /r means to locate bad sectors and recover readable information. Mostly, the correct form should be chkdsk /f /r. Basically, when we don’t know if the target drive contains bad sectors, we would suggest that you run the overall CHKDSK command: chkdsk /f /r /x together.
