How to Fix Can't Read from the Source File or Disk?

File transfer errors are fairly common on Windows, especially when moving large folders or data between devices. A frequent issue is the “can’t read source file or disk” message, which halts the process instantly. This can occur with external drives, memory cards, or even internal transfers, leaving users worried about data safety and frustrated when it interrupts important work without a clear cause.

Such errors can affect any storage hardware, though older drives are more prone due to wear and faults. Even newer devices may trigger the problem because of loose connections or file system glitches. The good news is that these issues are usually fixable.

Methods like checking connections, repairing the file system, or retrying transfers often restore access. With patience, users can recover their data and return the device to normal operation.

How to Fix "Can't Read from the Source File or Disk"?

This section explains practical solutions that help resolve issues found earlier. These steps work on most devices such as USB drives, memory cards, portable SSDs, and internal hard drives.

If you saw messages like can't read source file or disk or can't read file from source or disk, the methods below target every likely cause. Each method includes an explanation and steps that anyone can follow.

Method 1: Restart your computer and try again

Restarting the system may look basic, but it fixes many hidden issues. When your system runs for long periods, it collects temporary faults. These faults disrupt file paths and interrupt the connection between drives. A restart clears the memory, resets driver processes, and reconnects hardware components.

Many people dealing with how to fix can't read from the source file or disk find that a simple restart solves the problem.

Step 1: Save your work and close all open apps.

Step 2: Restart the computer and try copying the file again.

Method 2: Check and repair bad sectors using CHKDSK

Bad sectors cause many reading errors. CHKDSK scans the entire drive and marks or repairs damaged areas. This tool checks the surface of the drive and the file table structure. If your file sits on a bad spot, the system cannot read it.

This method helps restore access and often solves issues that cause messages like can't read file from source or disk.

Steps:

Step 1: Open Command Prompt as an administrator.

Step 2: Type chkdsk X: /f /r then press Enter.

Method 3: Run the disk error-checking tool in Windows

Windows has a built-in tool for checking file system errors. It is easy to use and helps locate broken paths inside the drive. It does not require typing commands. It is helpful for people who want to check the drive quickly.

This method solves many issues related to cannot read the source file or disk.

Steps:

Step 1: Open File Explorer and right-click the drive.

Step 2: Select Properties, choose Tools, then click Check.

Method 4: Try copying files with administrator privileges

Some files are locked behind admin controls. Without permission, Windows blocks access. This can cause can't read from the source file or disk in many cases.

Granting admin rights gives the system full control over the file.

Steps:

Step 1: Right-click the file or folder.

Step 2: Choose Run as administrator or open with admin rights.

Method 5: Use a different USB port, cable, or card reader

Hardware issues often look like software errors. A worn cable or loose connection interrupts data reading. Changing the port or using a new cable improves the stability of the transfer and often removes errors linked with faulty connectors.

Steps:

Step 1: Remove the device safely.

Step 2: Connect it using a new port, cable, or reader.

Method 6: Convert or reformat the drive to a compatible file system

If the drive uses a format that Windows does not support well, you may see read errors. Many external drives come pre-formatted for other systems. Reformatting removes conflicts. It is important to back up your data before formatting.

Steps:

Step 1: Back up your files to another location.

Step 2: Right-click the drive, choose Format, and select NTFS or exFAT.

Method 7: Scan for malware or viruses that may corrupt files

Viruses damage files and rewrite file paths. Some hide or lock items and stop the system from accessing them. A full scan removes threats and restores normal file behavior. This step is important because malware often causes read failures.

Steps:

Step 1: Update your antivirus program.

Step 2: Run a full scan of your system and the drive.
