Posted on Mar 28 2017 - 4:06pm by Techy Hints

Every file on the NTFS (New Technology File System) volume is presented in a particular file, known as MFT (Master File Table). This is the most significant system file, which defines the NTFS file system volume. In fact it is a relational database that contains different several about different files and directories. It works as central management feature and ‘starting point’ of NTFS partition. For proper accessing of a NTFS partition, it is required that the MFT must work properly. Sometimes, it gets damaged and you come across partitions loss situations. In order to retrieve lost partitions in such cases, Windows Partition Recovery is required.

In a practical scenario, when you boot your system Microsoft Windows XP SP2 (Service Pack 2) based computer, the Chkdsk utility automatically starts scanning the hard drive. Furthermore, the below error message is logged into the System Event log of your Windows computer:

“Event Type: Error

Event Category: Disk

Event ID: 55

Date: date

Time: time

User: N/A

Computer: computer name

Description: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume disk letter.”

After successful completion of the scanning process through Chkdsk tool, you can not access files and directories from Windows hard drive. All NTFS disk partitions experience this issue and serious partition loss situations arise. To retrieve lost partitions, you need to identify the cause of this problem and perform Partition Recovery by fixing it.


The problem generally occurs due to damaged or corrupted Master File Table of Windows hard drive. The corruption may occur due to virus infection, operating system malfunction, power surges, improper system shutdown, and user errors.
