How to Fix Corrupt Master File Table Error on Windows 10/11 [Safe Guide]
Facing a corrupt master file table error is one of the most stressful experiences for any PC user. When the Master File Table (MFT) fails, your computer effectively loses the map it uses to find every file on your hard drive. You might encounter terrifying messages like “The Master File Table is corrupt. Windows will attempt to recover it from the disk,” or find that your partition has suddenly become “RAW.”
While the situation seems dire, your data is often still physically present on the disk. The primary challenge lies in how you handle the repair process. Many users rush into deep system fixes that can accidentally overwrite their precious photos and documents. In this professional guide, we will explore why this error occurs and provide a step-by-step roadmap to repair corrupt master file table issues without losing your files.

What is the Master File Table (MFT)?
Before diving into the fixes, it is crucial to understand what you are repairing. In an NTFS file system, the Master File Table is a database that contains at least one entry for every file on the volume. It stores metadata, including file names, creation dates, access permissions, and most importantly, the physical location of the file’s data on the hard drive.
If the MFT becomes unreadable, Windows simply cannot “see” your files. Think of it like a library where the index cards have been shredded; the books are still on the shelves, but the librarian has no idea where to find them.
Common Symptoms of a Corrupt Master File Table
Identifying the problem early can save your hardware. Most users report the following “red flag” symptoms:
- CHKDSK Failures: You try to run a system check, but it says, “Windows cannot recover master file table. CHKDSK aborted.”
- RAW Drive Status: In Disk Management, your drive is listed as RAW instead of NTFS.
- Access Denied: You receive an error stating, “Drive is not accessible. The parameter is incorrect.”
- System Boot Failure: Windows fails to start because it cannot read critical system files indexed in the MFT.
Why Does the Master File Table Get Corrupted?
Understanding the root cause is the first step to a permanent repair corrupt master file table strategy. Based on technical evaluations, the most common causes include:
- Improper System Shutdown: A sudden power outage or a forced “hard” shutdown while the MFT is being updated is the leading cause of corruption.
- Malware and Viruses: Certain types of ransomware or boot-sector viruses specifically target the MFT to lock users out of their data.
- Hardware Bad Sectors: Since the MFT resides in a specific physical area of the disk, if that area develops “bad sectors,” the table becomes unreadable.
- External Drive Mishandling: Unplugging a USB hard drive without using the “Safely Remove Hardware” option often leads to a corrupt master file table.
Recover Data Before Attempting Repairs
We must emphasize a critical safety warning: Repairing the MFT is a high-risk operation. Standard Windows tools like CHKDSK work by attempting to move data and rewrite the file index. If the drive has physical damage, these “repairs” can permanently destroy the very data you are trying to save.
To ensure your files are safe, we strongly recommend using a professional recovery solution first.
Introducing Magic Data Recovery
Magic Data Recovery is a specialized tool designed to bypass corrupted file systems. Unlike standard Windows utilities that rely on a healthy MFT, this software performs a deep sector-by-sector scan of your storage media to find “orphaned” files.
Why Choose Magic Data Recovery for MFT Errors?
- RAW Partition Support: It excels at extracting data from drives that Windows labels as “Inaccessible” or “RAW.”
- Non-Destructive Scanning: The software operates in read-only mode, ensuring that it never overwrites the data it is trying to save.
- Comprehensive File Support: Whether you lost family photos (JPG, PNG), work documents (DOCX, PDF), or videos, the tool recognizes over 1,000 file types.
- User-Friendly Interface: You don’t need to be a computer scientist to use it; the three-step process makes recovery accessible to everyone.
How to use it:
- Scan: Select the drive with the corrupt master file table.
- Preview: Browse the found files to verify their integrity.
- Recover: Save your recovered data to a different healthy drive.
If you are looking for a reliable way to secure your digital life before tinkering with system commands, Magic Data Recovery provides the safety net you need.

4 Proven Ways to Repair Corrupt Master File Table
Once you have safely backed up your data using the tool mentioned above, you can proceed with these repair methods.
Method 1: Use the CHKDSK Utility
Windows includes a built-in tool called Check Disk (CHKDSK) that can fix minor MFT issues.
- Type cmd in the Windows search bar.
- Right-click Command Prompt and select Run as Administrator.
- Enter the command:
chkdsk C: /f(Replace “C:” with the letter of your corrupted drive). - If the prompt asks if you want to schedule the volume to be checked at the next restart, type Y and press Enter.
Note: If you see the message “Windows cannot recover master file table,” proceed to Method 2.
Method 2: Run SFC (System File Checker)
Sometimes the MFT error is related to corrupted system files that interact with the drive.
- Open Command Prompt as an administrator.
- Type
sfc /scannowand press Enter. - Wait for the process to complete. This tool will verify and repair protected system files that might be causing communication errors with the NTFS volume.
Method 3: Use TestDisk to Rebuild the MFT
For advanced users, TestDisk is an open-source utility that can specifically target the MFT mirror. NTFS keeps a backup of the MFT (called the MFT Mirror) in the middle of the disk.
- Run TestDisk and select your drive.
- Select the partition table type (usually Intel or EFI GPT).
- Go to Advanced > Boot.
- Select Repair MFT.
- TestDisk will compare the MFT and its mirror. If one is healthy and the other is not, it can use the healthy one to fix the corrupted one.
Method 4: Format the Drive (The “Fresh Start” Solution)
If the software-based repairs fail, the corrupt master file table may be a sign of logical structural collapse. At this stage, the most reliable way to repair corrupt master file table issues is to reformat the drive.
- Right-click the Start button and select Disk Management.
- Find the corrupted drive, right-click it, and select Format.
- Choose NTFS as the file system and perform a Quick Format.
Warning: This will erase all data remaining on the drive. Only do this after using Magic Data Recovery to save your files.
Proactive Tips to Prevent MFT Corruption
Prevention is always better than a cure. To avoid future MFT failures, consider these best practices:
- Use a UPS: An Uninterruptible Power Supply protects your PC from sudden power losses that corrupt file systems.
- Monitor S.M.A.R.T Status: Use tools to check your hard drive’s health. If you see “Reallocated Sectors Count” rising, replace the drive immediately.
- Avoid Overfilling: Try to keep at least 15% of your drive space free so Windows can easily manage the MFT expansion.
Final Thoughts
A corrupt master file table doesn’t have to mean the end of your data. While Windows offers several ways to repair corrupt master file table errors, these methods are often aggressive and risky.
The most professional approach is to prioritize data preservation. By using Magic Data Recovery to extract your files first, you eliminate the risk of permanent loss. Once your files are safe, tools like CHKDSK or TestDisk can be used with peace of mind.
