Files Get Lost After CHKDSK

Since you are here, it’s likely that you ran CHKDSK recently and finally found your files get lost after CHKDSK. Actually, you are not alone in this issue. Here are some real cases I’ve found on the internet.

Case 1: Files get lost after CHKDSK.

When Vista told me to run CHKDSK for my external hard drive, I foolishly did it. Then I saw a lot of "deleting index..." messages and I knew it was bad news. After CHKDSK, a whole lot of files, including personal backups, photos, videos, and some other files, got lost. Is there a good way to get these deleted data back? – MackoGetData forum

Case 2: All files disappeared on my secondary HD.

On my computer with Win7, after only one execution of CHKDSK, all files disappeared on my secondary HD (around 500 GB of very important data). I read the CHKDSK log file and it has found many mistakes on the HD including on the MFT. Is it possible to recover missing files as well as MTF? – GuukSuperuser

Then, I’d like to show you three methods about how to restore CHKDSK deleted files. Please keep reading.

Recover CHKDSK Deleted Data Using File History

File History is a backup tool included in the Windows operating system. It backs up files stored in Desktop, Documents, Downloads, Music, OneDrive, Pictures, and other standard Windows libraries.

If you have enabled File History before your data is lost, it is a good choice to restore data deleted by CHKDSK with it.

Step 1: Press Win + S and type Control Panel into the search box.

Step 2: Hit Enter to open the Control Panel window.

Step 3: Navigate to System and Security > File History > Restore personal files.

Step 4: Select the wanted file and click on the Restore button.

Recover CHKDSK Deleted Data from FOUND.000 Folder

FOUND.000 is a system folder that stores fragmented files recovered by CHKDSK. This folder often appears when you run the CHKDSK command to fix the disk error, like an incorrect system shutdown. You can recover files from the FOUND.000 folder but not a large amount of data. If you want to try this method to recover data deleted by CHKDSK, please follow the next steps.

Step 1: Press Win + E to open File Explorer.

Step 2: Select View on the top toolbar and check Hidden items to show the hidden folders.

Step 3: Then, you can find and double-click on the FOUND.000 folder.

Step 4: You will find lots of files with .chk extensions. To recover files from the folder, you can change the extension to the original extension of the file. For instance, if the file you want to restore is a PNG image, you can change the .chk to .png to achieve the goal.

However, there are numerous CHK files and it’s difficult for you to recognize the original format of every lost file. If you just need to recover a few files, you can try this method. If not, I heartily suggest you use MiniTool Power Data Recovery to retrieve files.

When and How to Run CHKDSK Properly

When to run?

Case 2:

When you open a file, you might receive an error message saying the file is corrupted and asking you to run the CHKDSK utility. Of course, such an error message might pop up from the lower right corner even if you are doing nothing. To deal with this issue, you can choose to delete the corrupted file or run CHKDSK to fix it. As long as the corrupted data is not that important, just delete it. On the contrary, run the CHKDSK utility to fix the problem.

If Windows asks you to run the CHKDSK utility frequently and report corruption on different files, it's likely that there are serious problems on your hard disk, and it may fail before long. To avoid data loss, it is wise to back up the hard disk with professional software, like MiniTool ShadowMaker.

Common CHKDSK Parameters

Functions of commonly used CHKDSK parameters are as follows:

  • /F: Fix 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.
  • /R: Locate bad sectors and recover readable information. The disk must be locked, too. In addition, /r does things /f does, but it is more multifunctional and powerful, and the only defect is that it costs much more time.
  • /I: Use with NTFS only. Performs a less vigorous check of index entries, reducing the amount of time needed to run CHKDSK.

For more parameters, please see Microsoft’s introduction to CHKDSK.

Recover Data after CHKDSK FAQ

Does <a href=https://www.minitool.com/data-recovery/chkdsk-f-or-r.html target='_blank' rel='noopener noreferrer' >CHKDSK /f</a> fix bad sectors?
The CHKDSK /f command will not check the drive it scans for bad sectors. In fact, this command is mainly used to check for software problems, such as file system corruption and other logical errors. To check & fix bad sectors, you should run the CHKDSK /r command.
How do I run CHKDSK /f?
Here’s how to run CHKDSK /f in Windows 10:
1.Click on the search icon/box on the taskbar.
2.Type cmd and choose Command Prompt.
3.Select Run as administrator.
4.Click Yes in the User Account Control window.
5.Type CHKDSK /f.
6.Press Enter on the keyboard.
Will CHKDSK fix corrupt files?
No, the CHKDSK will only fix the logical problems on the drive, not repair corrupt files. If you run CHKDSK without any parameters, it will scan your drive in read-only mode and report the errors it found. You should add the /f to it for repairing logical file system errors.
How long does a disk check take
There’s no exact answer to this question. However, the study shows it will generally take less than 30 minutes to run the disk check completely. It should be finished within 5 minutes to check a clean 1TB volume while the time will be much longer when checking a dirty one.
