Recently, some people reported that CHKDSK has deleted their data and they need to recover. You may have heard of CHKDSK, but you may not know well about what it is, what it is used for and how to deal with the situation when finding important files/folders are deleted by this command. In this article, I will show you how to recover and what CHKDSK is exactly.
Chapter 1 – CHKDSK Deleted My Data
If you’re careful enough, you’ll find lots of people have reported that “CHKDSK deleted my data”. If you are not so clear of what I’m talking about, please see the following two cases.
I booted up my Win 7 computer today and CHKDSK said my Ex HDD may have been corrupted and proceeded to delete some files. Those were some very important files - how can I get them back? (Video and Adobe Premiere Pro CS4 files). I prefer free methods on this - I know I can buy software to do this, but I currently don't have the money. Or a very cheap method, if nothing else. It's ironic that today was the day I was going to back up this drive. Please help!– posted by Ruester on Seven Forums
The computer he is using run CHKDSK (abbreviation of check disk) to fix the external hard drive that may be corrupted, but it turns out that the command has deleted some files very important to the owner. Now, here comes the most common reaction – he wants to recover files deleted by CHKDSK.
Every time I opened a file or folder on my computer it told me it wasn't there although I could see the icon. It also kept telling me to run chkdsk. I tried to change file extensions on the excel files so I could open them but it didn't work. So chkdsk ran the next time I rebooted and now the files are gone. Does anyone know how get a list of the files that chkdsk removed or is there a way to recover them? Thanks in advance.– asked by pumpkin ridge in Microsoft Community
His computer keeps telling him to run CHKDSK in order to fix the errors it has discovered; he refuses to run and tries to change file extensions to fix. Yet, it doesn’t work and when he boots the computer, he finds the files are gone. What should be done to recover files after check disk? Is there really a free or cheap method for recovering files after CHKDSK?
What to Do When Finding Files or Folders Missing after CHKDSK
As a free Windows command, CHKDSK is used for disk scanning and checking. Whenever unknown errors appear on your storage device (such as hard drive, USB flash drive, SD card, and memory stick), you can try to use this command to fix the error. Usually, it does a great job in checking and fixing the error, but deleting important files that people need also happens every now and then. At this critical moment, you must take measures immediately to recover CHKDSK deleted files.
Firstly, you should find a high-quality recovery tool.
MiniTool Power Data Recovery becomes a wonderful choice at this time. Why? Here are three leading reasons:

Next, you should carry out the data recovery as fast as you can.
As for how to recover deleted files from scan and fix, I’ll offer an in-depth tutorial in the next chapter. And then, in chapter 3, I’ll talk more about the CHKDSK command itself to help you have a better understanding of it.

4 Steps to Recover Files Deleted by CHKDSK
Before the recovery, you should choose from getting the trial edition to experience first or obtaining a license directly. You can click to know the specific differences among different licenses. In both cases, you are expected to finish the installation process properly right after you got the installation program. The last thing you should do to get ready for CHKDSK deleted files recovery is running the software at the end of the installation.
You should do the following things in order to recover data lost through CHKDSK (I take the trial edition as an example in this part).
Firstly, choose the most suitable option in the main interface. You should select “This PC” in the CHKDSK deleting files case.
If the deleted files are included in a mobile hard disk or a USB device, you’d better connect it to your computer before the first step. Besides, you need to select “This PC” to show a USB flash drive or “Hard Disk Drive” to show an external hard drive. Or, you can select “Removable Disk Drive” to show all external devices connected to the computer.
Secondly: select the drive that includes your data deleted by CHKDSK from the drive list on the right side of the software interface. And then, double click on it or press the “Scan” button to detect files.
Files and folders will be missing after CHKDSK is finished. If you would like to recover the lost files and folders successfully, you must figure out which is the drive that has been checked. After that, select it to scan.
Thirdly: open the found partitions one by one to see whether they include the important files and folders deleted by CHKDSK command. Then, check all the files you want to recover and press the “Save” button in the lower right corner.
Please note that you can browse the items and checked needed ones to recover during the scan or at the end of the scan.
Fourthly: the next thing you should do is setting a storage path for the checked files in the pop-up “Select a directory to save files” window. At last, press the “OK” button at the bottom of this window to start recovering lost files and lost folder after CHKDSK.
When all files have been saved to the appointed place, you can see a prompt window and you are allowed to close the software and end the work to recover data deleted by CHKDSK.
Till now, you must know well about how to recover missing files after CHKDSK, right? So please don’t be at a loss and saying “scan and fix deleted my files”. The sooner you take actions to recover files after check disk, the more files you’re able to find by using MiniTool Power Data Recovery.

Chapter 3 – CHKDSK Command Using Tips & Tricks
The full name of CHKDSK is check disk, as I said before, and it is designed for disk inspection after your system was shut down improperly or illegally. Of course, you can also manually call the command to check a specific disk partition, which is based on the file system used by the partition being detected. CHKDSK will create & display disk/partition status reports and list & correct errors on the disk/partition.
Three Stages of CHKDSK
The activities of CHKDSK can be divided into three main stages: check files, check indexes and check security descriptors. Let’s dive into them carefully.
Stage one: check files.
CHKDSK displays a message to inform you that it is verifying the files; the percentage of completed verification tasks (ranging from 0% to 100%) is also displayed. In this stage, CHKDSK will check each file record segment in the master file table (MFT) of the checked drive.
Stage two: check indexes.
CHKDSK also displays a message to inform you that it is verifying the indexes. Meanwhile, the percentage of completed verification tasks is also listed. CHKDSK will verify all the indexes on the checked drive during this process.
Stage three: check security descriptors.
Also, CHKDSK will display a message to inform you that it is verifying the security descriptors and show the percentage of completed verification tasks. In this stage, each security descriptor associated with the file or directory on the volume will be checked.

Notice the Following Things When Running CHKDSK
- CHKDSK can only be applied to check logical disk errors in the file system. To check the physical disk errors, you should use the SCANDISK program.
- CHKDSK can’t be used to allocate drives and networks. CHKDSK can neither be used for the working of drives created by the SUBST command nor be used for disk checks on network drives.
- CHKDSK will mark the bad sectors it found as "bad". Meanwhile, the SCANDISK and other physical disk error correction procedures will also mark the bad sectors as "bad", so they will not cause any damage.
- CHKDSK will report cross-linked file if there are two files or directories share the same disk space. But it will not fix the cross-linked file even if the item “/F” is specified. To repair a cross-linked file, you need to run the SCANDISK program or repair it manually, and then copy it to the specified file & delete the original file.
- Please don’t run CHKDSK when there is an opening The CHKDSK command is designed by assuming that all the disk files are off. So if you run this command when a file is opening, the corresponding MS-DOS will modify the file allocation table and directory structure. Those changes do not necessarily take place immediately; instead, changes in the file allocation table and directory structure occur at different times, so the error may occur, resulting in data loss or file system damage.
Chapter 4 – Verdict
Are you familiar with CHKDSK? Have you ever used CHKDSK to check and fix errors on your drive? If both answers are a big yes, you may understand that “CHKDSK deleted my data” is a common situation. The CHKDSK common is very useful sometimes, but you can’t avoid the troubles it may bring. As a result, the best way to minimize the losses resulting from the data loss trouble brought by CHKDSK is getting a powerful data recovery tool at hand.
Whenever you run CHKDSK and then find it delete your data during the scan and fix process, you should:
- Put an end to the command immediately.
- The next thing to do is starting the recovery tool in order to recover files and folders missing after CHKDSK in time.
The sooner you take action, the more likely you will recover all the deleted data.
You are advised to read the working stages of CHKDSK and the precautions for use to know better about this command and to avoid the unnecessary troubles as much as possible.
In addition, I advise you to backup the important data (if not all) on a regular basis. In this way, no matter what kind of disaster occurs and leads to serious data loss, you can deal with the situation directly and easily, without worrying too much about data security.
