This post is mainly about how to recover files deleted by CHKDSK. Specifically, 4 options are introduced. If you have lost your files after running CHKDSK, read this post carefully to get back your files.
“I ran CHKDSK to repair the file system corruptions on my hard drive. However, in the process of fixing the errors, CHKDSK deleted my files. These removed files are important to me. How can I recover files deleted by CHKDSK?”
Before getting to know how to recover files deleted by CHKDSK, you’d better get to know some common questions about CHKDSK.
CHKDSK, which stands for “check disk”, is a Windows utility that checks the file system integrity of a volume on your hard drive and repairs logical errors and bad sectors. It goes through all of the data listings, making sure that everything on the disk is correct.
The CHKDSK utility marks bad sectors on the hard disk so that Windows knows not to store or read data from those bad sectors. As a result, Windows stops accessing the marked bad sectors, resulting in the data stored in those bad sectors being permanently lost.
When you run CHKDSK, it does whatever is necessary to repair the logical file system, though it may result in data loss. The CHKDSK process has five stages, three of which are mandatory and two of which are optional. When you run CHKDSK in CMD, you can see the various stages of the utility.
Stage 1. File checks and verification
Stage 2. Examines volume indexes
Stage 3. Verifies the security descriptors for each Volume
Stage 4. Data verification (optional)
Stage 5. Checks for free space (optional)
Note: Stages 4 and 5 are two additional passes to look for bad sectors that are performed when the parameter /r is used while running CHKDSK; for example, chkdsk X: /r where X is the drive letter.
It is not a data recovery tool and will not recover lost or damaged files. CHKDSK will simply ensure the information currently on the disk is in a consistent and safe state. If files are damaged, the CHKDSK utility attempts to separate the damaged files and save the remnants as Filenn.chk.
Next, it's time to learn how to recover files that have been lost due to the CHKDSK utility. 4 tried-and-true methods for recovering files deleted by CHKDSK are mentioned here.
The first option to retrieve deleted files is to use professional data recovery software, such as MyRecover.
Download, install and launch MyRecover on your computer.
Step 1. Hover the mouse over the partition used to store the deleted files. Click Scan.
Step 2. Then the scanning process will start automatically. You don’t need to wait for the process to complete if you find the PowerPoint files you want to recover.
Step 3. Choose the files that you want to recover. Click Recover xx files and choose a destination path to save the restored files.
The second option to recover data with backup is to use Backup and Restore utility provided by Microsoft. But you need to make sure that you have enabled this service in advance.
Step 1. Navigate here: Control Panel > System and Security > Backup and Restore (Windows 7). Click on Restore my files to selectively recover permanently deleted files. You can also choose Restore all users’ files to get all deleted files back.
Step 2. Search for your PowerPoint files by using the Browse for files or Browse for folders option.
Step 3. Choose a location to save the backup, select your files and click Restore to recover them.
If you have turned on File History to save copies of your files, then you can get them back if they are deleted.
Step 1. Input Control Panel in the Windows search bar, and start it.
Step 2. Click System and Security.
Step 3. Click File History.
Step 4. Click Restore personal files.
Step 5. Select the files you need to recover and then click the Restore button.
The final option is to recover permanently deleted files using CMD via the tool Windows File Recovery.
Notes: The outcomes of this tool are unpredictable and it is only compatible with Windows 10 versions 2004 and up.
Preparation work before using Windows File Recovery:
To use this tool, check out your File System first. Go to This PC > right-click on the external drive that contains the deleted files > click Properties.
In addition, you need to use recovery mode and switches to get back your files. To decide which mode to use, refer to this table.
| File system | Scenarios | Mode |
| NTFS | Deleted recently | Regular |
| NTFS | Deleted for a while | Extensive |
| NTFS | Formatted disk | Extensive |
| NTFS | Corrupted disk | Extensive |
| FAT and exFAT | Any | Extensive |
Switches are used to filter the scanning range, thus can save the scanning time.
| Switches | Meaning | Supported mode(s) |
| /n | Filter the scan range: scans for a specific file with its file name/path/type, etc. | All |
| /y: | Recover specific extension groups. | Signature |
| /k | Recovers system files. | NTFSSegment |
| /u | Recovers undeleted files, for example, from the Recycle Bin. | NTFSSegment |
Step 1. Download and install Window File Recovery on your computer from Microsoft Store and then open it.
Step 2. Open Powershell or Command Prompt (run as administrator). In the Command Prompt, enter commands in the following command format:
winfr source-drive: destination-drive: [/mode] [/switches]
For example, if you need to recover deleted pdf files from F: drive (the external hard drive) to D: drive, then the command will be like:
winfr F: D: /regular /n *.pdf
The comments on CHKDSK are extremely polarizing. There have been numerous discussions in which CHKDSK has failed to repair a file and made it worse, while others believe that failing to use the CHKDSK utility even when prompted will result in a disk failure and, ultimately, data loss.
Whatever, you shall not be worried about data loss whether you have used CHKDSK or not as we have introduced 4 options on how to recover files deleted by CHKDSK command in this post. Besides, you can also use AOMEI Backupper to back up your system, disks, partitions, or files to avoid any kind of data loss.
