Can CHKDSK cause data loss? Does CHKDSK delete files?

Have you ever used CHKDSK to scan the hard disk for bad sectors? Users who want to recover corrupted hard drive might choose to use the CHKDSK command in Command Prompt to fix the errors.

But, to their astonishment, it sometimes runs into errors like CHKDSK cannot continue in read only mode; what's worse, it is said to cause data loss.


Lost files after chkdsk


Windows 7 Chkdsk searched my external hard drive for bad sector recovery, and it deleted hundreds of my most important folders and files. Unfortunately, I do have not any new backup from them.


- Question from SevenForums



Many customers have reported missing data after running the CHKDSK command, and they were asking does CHKDSK delete files on earth, and how to recover the files deleted by CHKDSK.

To begin with, it is necessary to figure out what does CHKDSK do.

What is CHKDSK? What does CHKDSK do?

CHKDSK is one of the Windows commands. It is used to check the physical and logical errors in the file system.

According to the Microsoft documentation, running chkdsk requires administrator authorization, and is only used for a local disk but not a net drive.

The chkdsk utility can work with parameters to execute some operations. When without any parameters, it only shows the status of the specified drive but won’t fix any problems.

The command format is:

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

Among these parameters, /f, /r, /b, etc., are used more frequently. Check the brief introduction.

/f Fix the errors on the disk.
/r Find and analyze the bad sectors on the disk and also recover readable info.
/b Clear the list of the bad clusters on the NTFS drive, and check the allocated and free clusters for possible errors.

The /r parameter is quite similar to the Recover command in CMD, some users will use it to recover data from corrupted hard drives.

Why does CHKDSK delete files?

So, why do files disappear after running chkdsk? Data loss may occur as a result of:

  • The chkdsk execution process is halted/interrupted.
  • Crash/shutdown/power off/restart without warning.
  • Virus infection of the file system or files.
  • Disconnect before the process is completed (for an external storage device).

Don't worry, we'll go through how to restore data erased by the chkdsk command in the next section.

How to recover files deleted by CHKDSK?

2 methods can help you restore files deleted after using the chkdsk command.

1. Convert files in the FOUND.000 folder into their original formats

After using the chkdsk command, you won’t notice any difference except the data loss, but a folder will be generated.

It is named FOUND.000, since it is a hidden system folder, you cannot access it normally as usual. But you could unhide it.

Step 1. Go to the source drive where the files were lost from > click View > toggle Hidden items.


Step 2. Find and open the FOUND.000 folder.


Step 3. Remember to tick the option File name extensions in View > right-click the CHK file > change the extension to the original extension of the lost files, e.g., jpg.


Thus the CHK files could be viewed and moved as normal.

If this method does not help, just move on to the next one.
