The CHKDSK cannot open volume for direct access error occurs when Windows cannot access a drive for repair. This article explains the common causes and provides effective solutions to restore drive access without losing data.
Quick Answer:
The “CHKDSK cannot open volume for direct access” error usually occurs because another program is locking the drive, the file system is corrupted, or the disk has physical issues.
To fix it, first restart your computer, switch to a rear USB port, or run CHKDSK in Safe Mode. Next, try removing or disabling third-party antivirus programs, antivirus software, or disk monitoring tools.
If the drive contains important files, recover your data first with professional data recovery software before formatting or replacing the disk.
Error Message: CHKDSK Cannot Open Volume for Direct Access
“I need help with my USB. I recently wanted to convert one of my MKV files into MP4 and suddenly the USB was removed from my PC.

The “CHKDSK cannot open volume for direct access” error appears when you run the CHKDSK command to scan and repair a disk, but Windows cannot gain direct access to the target volume.
When this error occurs, CHKDSK cannot complete the repair process, and you are unable to access files through File Explorer or view the drive properly in Disk Management.
This completely prevents you from accessing and backing up files on the disk.

Why Does the CMD Cannot Open Volume for Direct Access Error Appear
Based on many actual examples, before the CHKDSK error occurs, the disk has probably experienced a sudden power outage, abrupt removal, software installation or file transfer interruption, etc.
Various problems may occur during these processes, leading to the occurrence of this error message.
- Some third-party applications or services are occupying the disk which is checked by CHKDSK, making CHKDSK unable to access the disk.
- Third-party antivirus software installed on the computer is interfering with the normal operation of CHKDSK.
- The file system of the disk may have been damaged and cannot be recognized normally by CHKDSK.
- The physical components of the disk are damaged, such as the read/write heads, circuit boards, or other mechanical parts.
After identifying the possible cause, try the following solutions to restore access to the drive and recover your files.
How to Fix Cannot Open Volume for Direct Access CHKDSK
Fix 1. Switch to a Rear USB Port
Applicable case: This solution is especially useful when a USB drive appears as Unknown Device in Device Manager.
A poor USB connection may prevent Windows from identifying the storage device correctly, making CHKDSK unable to access it.
To fix the “cannot open volume for direct access” error, try connecting the USB drive to a rear USB port on your desktop computer.
If the drive becomes accessible after changing the USB port, immediately back up important files to another location.
Fix 2. Run CHKDSK in Safe Mode
Applicable case: This solution is useful when CHKDSK fails because a third-party program, antivirus software, or background service is locking the drive.
To verify whether the error is caused by interference from third-party software or services, you can boot Windows into safe mode and then run CHKDSK.
Safe mode is a specially developed troubleshooting mode that only loads key system components and the most basic drivers. Third-party startup items and services will not run automatically in this mode.
How to run CHKDSK in safe mode?
Step 1. Press the Windows + R key combination to open the Run box.
Step 2. Input msconfig in the input box and hit Enter.
Step 3. In the System Configuration window, go to the Boot tab. Tick the boxes of Safe boot > Network and click OK to start Windows in safe mode with networking.
Step 4. After the system reboots, you can run the CHKDSK again to repair your disk and verify if it can be completed successfully.
Fix 3. Disable Third-party Services & Uninstall Antivirus
Applicable case: This method applies when CHKDSK works in Safe Mode but fails during normal Windows startup.
If CHKDSK works fine in safe mode, it is likely that a third-party application or service is occupying the process, especially if you have recently installed any third-party applications.
You can check your computer to find these programs or services, especially antivirus software or disk management tools, and then disable or uninstall them.
How to disable a service:
Step 1. Press the Windows + R key combination, then type services.msc in the text box and press Enter.
Step 2. Right-click the target service and choose Properties.
Step 3. Expand the Startup type drop-down list and choose Disabled.
Step 4. Click Apply and OK sequentially to make this change take effect.
How to uninstall a program:
Step 1. Use the Windows search box to open the Control Panel.
Step 2. In the top right corner, choose Category from the View by drop-down list.
Step 3. Click Uninstall a program under Programs.
Step 4. Right-click the target application and choose Uninstall.
Fix 4. Recover Files & Format the Disk
Applicable case: This method applies when CHKDSK still cannot open the volume after trying all simple fixes.
If you still get the CHKDSK cannot open volume for direct access error and cannot access your files after trying the methods above, recover your data first. Then, format the drive to remove the corrupted file system and create a new one.
In the following sections, I will show you how to recover files from an inaccessible drive and how to format your disk in different ways.
Process 1. Recover Files From Corrupted Disk
To recover files from your disk, you can use MiniTool Power Data Recovery to scan the drive and check whether your files can be found.
MiniTool Power Data Recovery is a secure file restore tool that is designed for Windows 11/10/8.1/8 to recover all types of files. It is fully compatible with all file storage devices, including internal or external HDDs/SSDs, USB flash drives, SD cards, memory cards, and more.
Regardless of what the disk status is, as long as it can be recognized by the software, the tool can deeply scan the file system and find all existing files and deleted items that have not been overwritten by new data.
MiniTool Power Data Recovery Free allows you to scan and preview recoverable files before recovery. It supports recovering up to 1 GB of data for free.

Now, launch the installed MiniTool file restore tool to start secure data recovery.
Step 1. Scan the drive
When you enter the main interface of this tool, you are defaulted to the Logical Drives recovery module. Here you will see all partitions connected to your computer, including existing partitions, lost partitions, and unallocated space on internal or external disks.
If you are unsure which partition contains your lost files, switch to the Devices tab to scan the entire disk. Select the target disk based on its brand and capacity, then click Scan.
Step 2. Find your files
The scanning time depends on the drive size and the amount of data. For the best recovery results, wait until the scan finishes instead of stopping it midway.
After scanning, MiniTool Power Data Recovery will display all detected files, including existing files, lost files, and deleted files. You can use the following features to quickly locate the files you need:
- Path: This tab organizes files by their original folder structure. Expand folders to find your files. Note that some files may lose their original names or locations due to file system damage.
- Type: This tab sorts files by category and file format, making it easier to find specific data types, such as photos, documents, videos, or emails.
- Filter: Filter files by file type, modification date, size, or category to narrow down the results.
- Search: Enter part or all of the file name in the search box to find files that still have their original names.
Step 3. Recover your files
Double-click the target files to preview them before saving. Finally, click the Save button and select a directory to store the recovered files.
Process 2. Format the Disk for Further Use
Now I will show you how to format the problematic disk to a normal state so that you can use it to store files in the future.
Typically, disk formatting can be easily done by using File Explorer or Disk Management. Simply right-click the disk partition and choose Format, then fill in the required information and start the format.
However, you may be unable to format the disk from File Explorer or Disk Management when the CHKDSK cannot open volume for direct access error occurs.
If so, you can use MiniTool Partition Wizard to format the drive. The Format Partition feature is free to use.

Step 1. On the home page of this partition magic, select the target partition and choose Format Partition from the left menu bar.
Step 2. In the new window, set up the partition label, file system, and cluster size for the selected partition and click OK.
Step 3. Preview the format effect, and if it is satisfying, click the Apply button in the lower left corner to apply the change.
Fix 5. Disable Intel Volume Management Device
Applicable case: This method applies to a specific situation where Windows cannot start, and CHKDSK fails to run on the C drive.
On some newer Intel-based computers, the storage controller is managed through Intel Volume Management Device (VMD) technology. If the VMD setting changes unexpectedly, the system may fail to recognize the boot drive, and CHKDSK may fail to run.
Disabling Intel VMD in BIOS can help fix the CHKDSK error. The steps may vary depending on your computer manufacturer and model. Here we take ASUS as an example to show you the steps.
Step 1. Restart your computer. During booting, press F2 repeatedly to enter BIOS settings.
Step 2. After entering the BIOS configuration, press F7 to enter the Advanced Mode.
Step 3. Go to the Advanced tab, and then select the VMD setup menu option.
Step 4. Select Enable VMD controller, and choose Disabled from the drop-down menu.
