How to Fix Corrupt Master File Table Error on Windows

Encountering a corrupt master file table (MFT) error on your Windows PC is frustrating, indeed. It’s a critical NTFS file system structure holding all the vital information about every single file and directory on an NTFS volume. If you’re currently facing an error message indicating your master file table is corrupt, fear not. In this guide, we’ll explore various methods to fix the aforementioned issue and prevent potential data loss. Learn how to tackle corrupt master file table issues on Windows, with or without software, from personal experience.


Common Scenarios:

Unexpected System Shutdown 🌩

  • An unexpected power outage or forced system shutdown can cause file system inconsistencies, leading to a corrupted master file table.
  • Using the system during severe weather conditions can also risk sudden power loss and damage to the file system.

Malware Attack 🦠

  • Malware or viruses can corrupt system files, including the MFT, sometimes beyond repair if not addressed promptly.
  • Running an anti-virus scan and keeping security software up-to-date is crucial in preventing such scenarios.

Improper Disk Operations 💽

  • Interrupting disk operations such as formatting, partitioning, or resizing may lead to a corrupt master file table.
  • Always ensure that disk management tasks are completed without interruptions to maintain data integrity.

Step-by-Step Guide. Corrupt Master File Table:

Method 1: Use Windows CHKDSK Utility 🛠

  • Boot your computer into Windows Recovery Environment (WinRE).
  • Select Troubleshoot > Advanced options > Command Prompt.
  • Type ‘chkdsk /f /r’ followed by the drive letter (for instance, chkdsk /f /r C:) and press Enter.
  • Wait for the utility to check the disk and automatically fix file system errors.

Note: It’s essential to back up your data before performing this check, as the process may lead to data loss in some cases.

Conclusion: Running the CHKDSK utility can often repair minor file system errors, including issues with the master file table.

Method 2: Perform System Restore 🔄

  • Access System Restore by typing ‘Create a restore point’ in the Windows search bar and selecting the corresponding result.
  • Click on ‘System Restore…’ in the System Properties window.
  • Follow the on-screen instructions to restore your system to a prior state.

Note: System Restore will only be effective if you have previously set up restore points.

Conclusion: Reverting to a point before the corruption occurred can sometimes resolve the issue without affecting your personal files.

Method 3: Use SFC (System File Checker) ✅

  • Open Command Prompt as an administrator by right-clicking on the Start button and selecting ‘Command Prompt (Admin)’.
  • Type ‘sfc /scannow’ and press Enter.
  • The SFC tool will now scan for and attempt to repair any corrupted system files.

Note: This process can take some time, depending on your system’s specs and the extent of the corruption.

Conclusion: System File Checker is an integrated Windows utility that can fix corrupted system files, possibly including those related to the master file table.

Method 4: Check for Malware 🛡

  • Run a full system scan with Windows Security or another reliable antivirus software.
  • Quarantine or remove any detected malware or viruses.
  • Consider using dedicated malware removal tools if infections persist.

Note: Some infections might require the PC to be booted in Safe Mode to be successfully removed.

Conclusion: Eliminating viruses or malware is crucial, as they can be the underlying cause of file system corruption, including a corrupt master file table.

Method 5: Repair Install Windows 🔄

  • Download the Windows Media Creation Tool from Microsoft’s official website.
  • Create a bootable USB or DVD and boot from it.
  • Select ‘Upgrade this PC now’ to initiate a repair install, which will refresh all of Windows’ system files.

Note: A repair install should ideally preserve your personal files and applications but backing them up is recommended.

Conclusion: A repair installation can replace corrupted system files without removing personal data or installed applications.


Precautions and Tips:

Handle with Care ⚠

  • Avoid abrupt system shutdowns by using an Uninterruptible Power Supply (UPS).
  • Regularly create system restore points to facilitate easy recovery in the event of system file corruption.
  • Always use the Safely Remove Hardware and Eject Media option when disconnecting external storage devices.

Maintaining File System Health

The key to preventing file system corruption is regular maintenance and vigilance. Make it a habit to routinely check your system for errors using Windows’ built-in tools, and keep an eye out for signs of malware. Disk optimization through tools like ‘Defragment and Optimize Drives’ can also promote data integrity and performance.

Disk imaging software, such as Macrium Reflect or Acronis True Image, provide an additional layer of data protection by allowing the creation of a complete snapshot of your system, which can be restored in case of corruption.

Moreover, always ensure your software and operating system are up to date with the latest security patches and bug fixes. This includes not only Windows updates but also updates to drivers that can affect your hard drive’s health.


Addressing a corrupt master file table is a delicate task that requires a methodical approach. While the solutions provided here can resolve the majority of issues, it’s imperative to maintain a regular backup routine and promptly address any signs of system instability to reduce the likelihood of serious corruption. Don’t forget, an ounce of prevention is worth a pound of cure. For more detailed assistance on dealing with corrupt master file table, you can delve deeper into technical resources or seek professional help.


A corrupt MFT may lead to error messages indicating missing or damaged files, inaccessible drives, blue screen errors, or system crashes when attempting to access certain files.

The MFT can become corrupted due to hardware failures, software glitches, sudden power outages, or malware attacks that interfere with the file system.

The built-in Windows utility chkdsk can be used to check the integrity of the filesystem and attempt to repair corrupt MFT issues.

Yes, a corrupt MFT can lead to partial or complete data loss if the table cannot map the stored files correctly for retrieval.

Data recovery software may be capable of restoring data from a drive with a corrupt MFT by bypassing the file system and directly accessing files. Visit official data recovery service providers such as Ontrack for professional assistance.

While anti-virus software is crucial for preventing malware attacks, which can cause MFT corruption, it cannot prevent all types of corruption, such as those due to hardware failures.

Formatting the drive will create a new MFT, effectively removing the corruption, but this process will also erase all existing data on the drive.

A disk defragmenter will not fix a corrupt MFT, as its purpose is to reorganize data for efficiency, rather than repair the filesystem structure.

Windows includes features like Shadow Copies and regular automatic backups that help protect against data loss, which may indirectly prevent severe MFT corruption consequences.

If Windows cannot read essential files due to MFT corruption, you may be unable to boot. Booting from a recovery drive or installation media may be necessary.
