Fix “Can’t Read from the Source File or Disk” Error in Windows 11

The “Can’t read from the source file or disk” error in Windows 11 is a frustrating issue that usually appears when you try to copy, move, or delete files. This error typically indicates a problem with file accessibility, storage media, or system-level conflicts. 

It can occur due to corrupted files, bad sectors on a disk, file system errors, permission restrictions, or even issues with external devices like USB drives or external hard disks.

In this guide, you will learn a step-by-step approach to diagnose and resolve the issue using built-in Windows tools and practical troubleshooting methods.

Let’s do it!

Fix “Can’t Read from the Source File or Disk” Error in Windows 11

To fix the “Can’t read from the source file or disk” error in Windows 11, check the disk for errors, ensure proper file permissions, verify file paths, and repair corrupted sectors using built-in tools like CHKDSK. Updating drivers and reconnecting storage devices can also resolve the issue.

Step 1: Restart Your Computer and Reconnect Devices

Start with the simplest solution. Restarting your system refreshes background processes and clears temporary glitches.

If you are working with an external storage device such as a USB drive or external hard disk, disconnect it safely and reconnect it after restarting your computer.

Ensure that the cable is properly connected and try using a different USB port. Sometimes, loose connections or faulty ports can trigger read errors.

Step 2: Check File Name and Path Length

Windows has a limitation on the length of file paths. If the file name or folder structure is too long, the system may fail to access it.

Rename the file or move it to a location with a shorter path, such as the Desktop. Avoid using special characters or excessively long folder names.

This simple adjustment can resolve the issue if it is caused by path length restrictions.

Step 3: Run CHKDSK to Repair Disk Errors

The CHKDSK utility is one of the most effective tools for fixing disk-related problems. It scans your drive for errors and repairs bad sectors.

Open Command Prompt as an administrator and type the command to scan the affected drive.

Allow the process to complete fully. This may take time depending on the size of the disk.

After the scan, restart your system and check if the issue is resolved.

Step 4: Check for Bad Sectors on the Drive

Bad sectors can prevent files from being read or written properly. These are damaged areas on a disk that cannot store data reliably.

Use the built-in disk checking tool in Windows by accessing the drive properties. Navigate to the Tools tab and run the error-checking feature.

If bad sectors are detected, Windows will attempt to repair them or isolate them to prevent further issues.

Step 5: Verify File Permissions

Sometimes, the error occurs because you do not have the required permissions to access a file.

Right-click the file or folder and open its Properties. Go to the Security tab and ensure that your user account has full control.

If necessary, modify the permissions to grant access. This step is especially important when dealing with files copied from another system.

Step 6: Disable Antivirus Temporarily

Certain antivirus programs may block file operations if they detect suspicious behavior.

Temporarily disable your antivirus software and try the file operation again. If the issue is resolved, add the file or folder to the antivirus exclusion list.

Remember to re-enable your antivirus after completing this step to maintain system security.

Step 7: Update Disk Drivers

Outdated or corrupted drivers can cause communication issues between the system and storage devices.

Open Device Manager and locate your disk drives. Check for updates and install the latest drivers available.

Restart your computer after updating the drivers to apply the changes.

Step 8: Use Safe Mode to Access Files

Booting into Safe Mode loads only essential system services and drivers. This can help bypass conflicts caused by third-party applications.

Enter Safe Mode and attempt to copy or access the file again. If it works, the issue is likely caused by a background program interfering with the process.

Step 9: Try Copying Files Using Command Prompt

If File Explorer fails to read the file, you can use Command Prompt as an alternative.

Use commands like copy or xcopy to transfer the file. These tools can sometimes bypass errors that occur in the graphical interface.

This method is particularly useful for recovering important files.

Step 10: Format the Drive as a Last Resort

If the issue persists and affects an entire drive, formatting may be necessary.

Before proceeding, back up all important data if possible. Formatting will erase all files on the drive.

After formatting, the drive will have a fresh file system, which often resolves persistent errors.
