CHKDSK Deleted Files: How to Undelete/Recover Files Deleted by CHKDSK CMD Command

CHKDSK is a utility commonly used by Windows users to repair errors on their storage devices. However, in some instances, running this utility can lead to data loss. In this guide, we’ll provide an overview of CHKDSK and demonstrate how to recover files lost after using the CHKDSK Windows utility.

What is CHKDSK?

CHKDSK is a tool included in Windows that ensures that the file system isn’t corrupt and it can also fix logical file errors. Actions such as improperly shutting down a computer, removing USB drives without safely ejecting them, and other things like viruses and malware can possibly corrupt the file system or cause logical file errors. If CHKDSK happens to cause files on your computer to be deleted, you have some options for recovering them which we will examine below.

What Can Cause CHKDSK to Delete Data

While CHKDSK is useful, there are a few scenarios that might cause it to delete files. Unfortunately, Superuser user Chindraba experienced this, as did this Reddit user and this Spiceworks user.

We will cover some of the scenarios that might cause something like this to happen, below:

• 🚫 CHKDSK is interrupted: An event such as a shutdown or a restart while running CHKDSK can result in your files being deleted. Avoid shutting down or restarting your computer while running CHKDSK to avoid running into any issues.
• 💾 Running CHKDSK on a corrupt or damaged hard disk: If a hard drive is damaged or corrupted, there are sectors that may become inaccessible eventually. The more you use the drive, the faster these sectors will become inaccessible. If your hard disk is corrupt or damaged, you should back up your data immediately or seek out the services of a professional data recovery service if the damage is severe.
• ⛔ CHKDSK finds bad sectors: If CHKDSK finds bad sectors on your hard drive, it will mark them as bad. Windows will see this and won’t store or read data from these bad sectors. If data is stored on these bad sectors, it could be lost permanently.

Is It Possible to Recover Files Deleted by CHKDSK?

It is possible to recover data from a storage device that has had files deleted by CHKDSK even if the issue is related to the drive having bad sectors. Advanced data recovery software such as Disk Drill Data Recovery has the scanning algorithms to handle tricky scenarios like this.

After a while, the files in these blocks are permanently deleted. If this happens, you won’t be able to recover your files. You will need to do the following if you are trying to recover files deleted by CHKDSK on an SSD with TRIM enabled:

1. Create an image of your SSD. If your drive is failing, this is crucial since your drive could stop working at any moment.
2. Scan the backup image with data recovery software to attempt file recovery. We cover how to use data recovery software below.

How to Recover Files Deleted by CHKDSK

Since files aren’t immediately removed from your computer’s hard drive after the deletion, we can take advantage of this to actually recover data deleted by CHKDSK. A third-party tool such as Disk Drill can be used to recover these files or, if you keep regular backups, you may be able to restore a copy of the file that was deleted.

Using Disk Drill to Recover Files That Were Deleted by CHKDSK

Disk Drill is an advanced file recovery application that is available for Windows and macOS. It can recover more than 400 different types of files, which makes it one of the best data recovery applications that is available on the market. Although it is quite an advanced tool, it is still easy to use.

Here’s how you can use Disk Drill to recover files that were deleted by CHKDSK:

1. You will first need to download and install Disk Drill. After Disk Drill is installed, when you go to run it, you will be asked to grant the application admin permissions. This allows Disk Drill to run its advanced algorithms so that it can attempt to recover the maximum amount of files. When the Disk Drill window opens, select the drive that you want to recover files from to get the process started.
2. Selecting “Search for lost data” will start the search. This initiates an in-depth scan of the selected drive, allowing Disk Drill to identify any recoverable data. Depending on the size of the drive and the amount of data, this process can take some time.
3. After the search has been completed, you will then need to locate the files that you actually want to recover. After the search, Disk Drill displays a list of the files that it found. You can filter by category to help you to quickly locate the type of file that you want to find. For example, searching under Audio will show you all of the audio files that were found in the search.
4. Now, save the files that you want to recover. Make sure that you save these files to a storage device that isn’t the one you’re recovering from. Doing this may overwrite the files that you’re trying to save. When the files have been saved, Disk Drill will display a confirmation message letting you know if the process worked or not.

Recovering Files Deleted By CHKDSK Using Windows’ File History Feature

If you had previously set up Windows’ File History feature before the data loss occurred, you’re in luck. This feature can help you recover files that may have been deleted by CHKDSK. If you didn’t have this feature enabled before the loss, unfortunately, it won’t help in recovering the lost data.

How to Restore Deleted Files Using File History

For those who had it set up, here’s how you can use it to restore your files:

1. First, you need to start the restore process. To do this, in the Windows Settings app, go to Update & Security followed by Backup, then select Restore files.
2. You will now be able to browse to the folder where the files were originally located. If there is a backup of the file, you will see it, and from there you can restore it by selecting the green Restore button.

Setting Up File History for Future Protection

To prevent future data losses, it’s a good idea to set up File History now. Here’s how you can do it: You will need to do the following to get set up with File History:

1. Open the Settings app in Windows 10 and go to Update and Security.
2. Now, select the Backup option from the left sidebar.
3. After selecting the Backup screen, you will be able to select the drive that you want to use for backing up your files by selecting Add a drive.
4. After completing this, switch on automatic backups to ensure that you don’t have to think about manually completing backups. You can do this by switching the “Automatically back up my files” toggle on.

Wrapping Up

CHKDSK is a useful Windows utility, but under some circumstances, it may lead to data loss. Luckily, using data recovery software such as Disk Drill can help users recover data if they ever run into issues with CHKDSK deleting files. In addition, the File History feature can also help users recover CHKDSK deleted data.

Additional Tips for Using CHKDSK Safely:

• Always back up your data before running CHKDSK, especially if you suspect the hard drive is corrupt or damaged.
• Avoid interrupting CHKDSK once it’s in progress.
• If you’re running CHKDSK on a system drive, ensure you boot from a Windows installation disk or a recovery drive.
