In today’s digital age, efficient file management is crucial for both personal and professional tasks. However, you may occasionally encounter frustrating errors that hinder your workflow. One such issue is the ‘Can’t Read from Source File or Disk’ error, which can prevent you from accessing, copying, or moving your important files. This comprehensive guide will help you understand the causes of this error and provide effective solutions to resolve it.
Understanding the ‘Can’t Read from Source File or Disk’ Error
The ‘Can’t Read from Source File or Disk’ error is a common issue that occurs during file transfer operations, typically when moving data between different drives or storage devices. This error indicates that your system is unable to access a specific file or disk, often due to underlying issues with file systems, hardware, or software compatibility.
When this error occurs, you may find yourself unable to:
- Copy files from one location to another
- Move files between drives
- Delete files that are no longer needed
If left unresolved, this error can lead to data loss, especially if the affected files are stored in damaged sectors of your hard drive. It’s particularly common when transferring large files or when moving data between external and internal storage devices.
Common Causes of the ‘Can’t Read from Source File or Disk’ Error
Understanding the root causes of this error is crucial for effective troubleshooting. Here are the most common reasons you might encounter this issue:
Mismatched File Systems
Different storage devices may use varying file systems, such as NTFS, FAT32, or exFAT. When transferring files between incompatible file systems, you may encounter errors. For instance, FAT32 has a 4GB file size limit, which can cause issues when transferring larger files to or from a FAT32-formatted drive.
Bad Sectors on Hard Drives
Bad sectors are damaged areas on your hard drive that can no longer reliably store data. These can be caused by physical damage, manufacturing defects, or software issues. When your system attempts to read data from a bad sector, it may trigger the ‘Can’t Read from Source File or Disk’ error.
Connection Issues
For external storage devices, problems with USB connections can lead to file transfer errors. This could be due to faulty USB cables, damaged ports, or loose connections. Using a reliable hard drive docking station can help mitigate these issues.
Unsupported File Names
Windows has specific naming conventions for files and folders. Using characters like ?, <, >, :, *, /, , |, or ” in file names can cause compatibility issues and trigger errors during file operations.
Insufficient Storage Space
If the destination drive doesn’t have enough free space to accommodate the files you’re trying to transfer, you may encounter this error. This is often related to the 0x80070070 error, which indicates insufficient disk space.
File Permissions Problems
Incorrect file permissions can prevent your system from accessing certain files, leading to the ‘Can’t Read from Source File or Disk’ error.
Initial Troubleshooting Steps
Before diving into more advanced solutions, try these simple troubleshooting steps:
Restarting Your Computer
A simple restart can often resolve temporary system glitches that may be causing the error. This refreshes your system and clears any transient issues affecting file access.
Checking USB Connections
If you’re working with external drives, ensure all USB connections are secure. Try different USB ports or cables to rule out hardware issues.
Renaming Problem Files
If you suspect the error is due to unsupported characters in file names, try renaming the problematic files. Remove any special characters and use simple, alphanumeric names.
Verifying Available Storage Space
Check that your destination drive has sufficient free space for the files you’re trying to transfer. If necessary, free up space by deleting unnecessary files or moving them to another location.
Advanced Solutions for ‘Can’t Read from Source File or Disk’
If the initial troubleshooting steps don’t resolve the issue, try these more advanced solutions:
Running CHKDSK Command
The Check Disk (CHKDSK) utility can help identify and repair bad sectors on your hard drive. To run CHKDSK:
- Open Command Prompt as Administrator
- Type
chkdsk X: /f(replace X with your drive letter) and press Enter - Wait for the process to complete and restart your computer if prompted
This process is similar to resolving the 0x80300001 error, which often involves disk-related issues.
Using Alternative Software
If the default program can’t open or transfer a file, try using alternative software. Different programs may handle file formats differently, potentially bypassing compatibility issues. This is especially important when dealing with system files like datastore.edb.
Adjusting File Permissions
To check and adjust file permissions:
- Right-click on the problematic file and select ‘Properties‘
- Go to the ‘Security‘ tab
- Click ‘Edit‘ and ensure your user account has ‘Full control‘ permissions
- Apply the changes and try accessing the file again
Compressing Files for Transfer
If you’re dealing with large files, try compressing them into a ZIP archive before transferring. This can reduce file size and potentially avoid errors related to file system limitations.
Preventing ‘Can’t Read from Source File or Disk’ Errors
To minimize the chances of encountering this error in the future, consider these preventive measures:
Regular Disk Maintenance
Perform regular disk checks and defragmentation to keep your storage devices in good health. This can help prevent bad sectors and maintain optimal performance.
Ensuring File System Compatibility
When possible, use the same file system across your storage devices. NTFS is generally recommended for Windows users due to its robustness and lack of file size limitations.
Backing Up Important Data
Regularly back up your important files to multiple locations. This ensures that even if you encounter errors, your data remains safe and accessible. Consider using a high-performance laptop for video editing to handle large file transfers efficiently.
Avoiding Unsupported Characters in File Names
Stick to simple, alphanumeric file names to avoid compatibility issues. This practice can prevent many file-related errors, including the Steam disk write error.

Frequently Asked Questions
- Q: Can this error occur with both internal and external disks? A: Yes, the ‘Can’t Read from Source File or Disk’ error can affect both internal and external storage devices, including hard drives, SSDs, and USB drives.
- Q: Will running a disk error check erase my data? A: Generally, no. Disk checking utilities like CHKDSK are designed to fix errors without deleting data. However, it’s always wise to back up important files before performing any disk operations.
- Q: What should I do if none of the mentioned methods work? A: If you’ve tried all the solutions without success, consider consulting a professional technician or contacting the manufacturer of your storage device for specialized assistance.
- Q: Can I recover files from a physically damaged disk? A: While it’s sometimes possible to recover data from a physically damaged disk, it often requires professional data recovery services. The success rate depends on the extent of the damage.
- Q: How can I differentiate between a software-related issue and a hardware-related issue? A: If the error occurs consistently across multiple files or disks, it’s more likely to be a software issue. If it’s specific to a particular file or disk, it may indicate a hardware problem. Persistent issues after software troubleshooting may point to hardware failure.
By following this guide, you should be well-equipped to tackle the ‘Can’t Read from Source File or Disk’ error and maintain a smooth, error-free file management experience on your Windows system. Remember to keep your system optimized to avoid related issues like screen tearing, which can affect your overall computing experience.
