What is an MFT Record


Master File Table

MFT stands for Master File Table, which is a database used by the NTFS file system in Windows operating systems to store information about files and directories on a disk. Every file and directory on an NTFS volume has a corresponding record in the MFT, which contains information such as the file name, creation and modification dates, permissions, and attributes.

The MFT record is a data structure that describes a particular file or directory on an NTFS volume. It contains information such as the file or directory's name, size, creation and modification times, ownership, permissions, and data content. Each MFT record has a unique identifier called a file reference number, which is used by the file system to locate the record on the disk.

The MFT record is an essential component of the NTFS file system and is used by many Windows utilities and applications to manage files and directories on the disk. Understanding how the MFT works can be important for tasks such as data recovery, disk analysis, and disk optimization.

What is an unexpected MFT Record


An "unexpected" MFT record typically means that the record is corrupted or damaged in some way, causing the file system to encounter an error when attempting to read or write data to that file or directory. This error can result in a variety of issues, such as file system crashes, data loss, or inability to access certain files or directories.

There can be many reasons why an MFT record becomes unexpected, including hardware failures, software bugs, malware infections, or improper system shutdowns. To fix the issue, the first step is to run a disk check utility to identify and repair any errors on the disk. In some cases, more advanced data recovery tools may be necessary to recover data from the damaged MFT record or repair the file system.

It is always recommended to regularly backup important data to prevent data loss in case of unexpected MFT record issues or other disk-related problems.


How to fix an unexpected MFT Record

Fixing an unexpected MFT record will depend on the specific cause of the issue. Here are some general steps that can be taken to try and resolve the issue:

  1. Run a disk check: The first step is to run a disk check utility such as CHKDSK in Windows to scan the disk for errors and repair any file system issues. To do this, open a command prompt as administrator and type "chkdsk /f /r" and press Enter. This will scan the disk for errors and fix any issues found.

  2. Use data recovery tools: If the disk check utility is unable to fix the MFT record issue, data recovery tools such as EaseUS Data Recovery Wizard or Recuva can be used to recover data from the damaged MFT record.

  3. Use MFT repair tools: If the MFT record is corrupted or damaged, there are specialized MFT repair tools available such as TestDisk, MFT Recovery Toolkit, or DMDE, which can be used to repair or rebuild the MFT record.

  4. Seek professional help: In some cases, if the MFT record issue is severe or data is critical, it may be best to seek professional help from a data recovery service or a computer technician who can perform more advanced repairs.

It is important to note that any attempt to fix the MFT record issue should be done with caution and backup important data before making any changes to the disk.
