CHKDSK is a utility that checks and repairs disk errors to ensure that your computer's files and file systems are in logical order, while detecting and repairing bad sectors. Although CHKDSK is very powerful, in some cases, you may receive a 'CHKDSK cannot continue in read-only mode' error message during use, as described in the above case. If you want to fix the CHKDSK cannot continue error as soon as possible, please understand thecause of the error first.
The following are common causes of errors.
The following 8 methods can help you to fix 'CHKDSK cannot continue in read-only mode' error easily, just follow the steps.
If the target drive is being used by another application, you will receive the 'CHKDSK cannot continue in read-only mode' error during the CHKDSK process. At this point, you can set the next reboot to perform a CHKDSK scan to bypass the above error.
If the above method fails, you can also use CHKDSK from Windows Recovery Environment (Windows RE), which will help you fix the error that CHKDSK cannot execute in read-only mode.
3. Next, your computer will restart automatically. You can enter the following commands in the command prompt character window according to actual requirements, and press Enter to execute the command.
chkdsk x: (check disk for errors and not fix)
chkdsk x:/f (checks and fixes disk errors but does not scan for bad sectors)
chkdsk x:/r (checks and fixes disk errors and scans for bad sectors)
Please replace the x in the above command with another disk letter.
If the target hard disk is set to read-only mode, it will result in CHKDSK read-only mode and you will receive the error 'CHKDSK cannot continue in read-only mode'. Therefore, to fix the above error, you can change the read-only mode to normal mode.
In some cases, a 'CHKDSK cannot continue in read-only mode' error occurs when the disk is write-protected. If you want to fix the above error, you can try removing the write-protect feature on the disk from the login editor.
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBHUB3
If the target drive is being used by another application, you can try closing all executing files or applications to fix the 'CHKDSK cannot continue in read-only mode' error. It is recommended that you do this in the Task Manager.
Use ESC+Shift+Ctrl to open Task Manager and view suspicious files or applications in the Handlers tab list. If you find a suspicious file or application, right-click it and select End Task.
You may also encounter the 'CHKDSK cannot continue in read-only mode' error while using CHKDSK if there is a virus or malware on the disk. To fix the above errors, you need to scan for and remove these viruses and malware.
Note: If you are not confident enough about Windows Defender's antivirus capabilities, you can also install and run powerful third-party antivirus software such as Bitdefender,Norton, Kaspersky, etc. to scan again to ensure that the disk is not compromised by viruses.
Windows System File Checker (SFC) is a utility that can help you check and repair corrupted system files. Since corrupted system files are a significant cause of the 'CHKDSK cannot continue in read-only mode' error, you can fix this error through SFC.
If none of the above methods help you to fix the 'CHKDSK cannot continue in read-onlymode' error, then you can only format the disk to fix the above error. Please be aware that formatting a disk will result in the loss of all data on it, and it is recommended that you make a disk backup before proceeding .
Note: As long as there are no special needs, it is recommended that you choose the NTFS format. Also, since the full format automatically scans and repairs bad sectors in the disk, it is recommended that you need to cancel the quick format.
