How to Restore Partition Table?

Partition Table is a data structure on physical hard drives that provides an efficient way to manage logical partitions present on that drive. It is a part of Master Boot Record (MBR) that is stored in boot sector, which is a crucial section on the hard drive responsible to carry out tasks like computer start up, loading OS, etc. Partition Table holds all the information regarding all the logical partitions of that hard disk like size, start and end points of each partition, total number of partitions, etc. Hence, it is an essential part to perform data activities on partitions of the hard drive.

However, this partition Table can get corrupt and unresponsive due to many factors which in turn result to inaccessibility of partition data on the drives. For instance consider that, you used an unknown partitioning tool to create new partitions on your computer hard drive. During the process, you were misled by giving wrong commands and the process failed saying that Partition Table is invalid. Apart from this, there are other reasons too that end in corrupting Partition Table of a hard drive.

Few common scenarios that affect partition table of a hard disk are:

  • Using command prompt to erase / clean MBR of hard drive without backing up data will delete the entries of partitions in partition table
  • Accessing Disk Management utility without sufficient knowledge might sometimes lead to loss or deletion or corruption of partition table on the system drive
  • Undesirable changes made to boot sector or master boot record can also result in damaging partition table in unseen scenarios
  • Abrupt termination of system like switching off the power button instead of performing formal shut down process, use of inefficient defragmentation tool, repartitioning tool, disk cleaner, etc. will also render loss or damage of partition table
  • Most of the other times, virus infection, improper installation of OS, installing multiple OS, etc. can all lead to corruption of partition table or complete hard drive leading to severe data loss

When partition table is corrupt or lost from MBR of the hard drive, the partitions present on hard drive becomes unreadable and hence, users suffer from data loss. In all such instances, the best and first thing to do is to stop using the hard drive for any data activities. Because, performing any activities like storing new data, or reinstalling OS, etc. might overwrite original data and cause permanent loss of entire crucial data from the drive.

Now, let us see how to perform recovery of partition table:

In order to get back partition table and all the partition data from the hard drive after encountering any of the situations, make use of Yodot Hard Drive Recovery software. It is a simple-to-use recovery tool that retrieves all your data from damaged, corrupted, unbootable, failed and dead hard drives of Windows PCs and laptops with utmost ease. The software is excellent in restoring data like documents, text, pictures, videos, partitions, folders and other system related program files from hard drives interfaced with SATA, SCSI, ATA, IDE, PATA, etc. This application can recover data from internal as well as external hard drives formatted or reformatted with FAT32, FAT16, NTFS, NTFS5, ExFAT and ReFS file systems. Apart from hard disk drives, it can even bring back lost data from USB drives, Firewire drives, etc. storage components. The tool is compatible to work on Windows computers like Windows 8, Windows 7, Windows XP, Windows Vista, Windows Server 2003 and Windows 2008.

Steps to get back partition table:

  • Connect the victim hard drive to a healthy Windows computer
  • Then download and install Yodot Hard Drive Recovery on that Windows system
  • Launch the utility after complete installation and stick to the main screen
  • Here, click on ‘Partition Recovery’ option to bring back partition table data
  • In next screen, choose the drive from which partition table has to be recovered (click on the drive representing externally connected victim hard drive)
  • Then, if required select the file types that you wish to recover or simply click on Mark All
  • Software performs a quick scan and results with a list of restorable files from the drive
  • Go through the files in Data View or File Type view options and mark required ones
  • Save the rescued files in target location on host system drive or other external storage drives other than the victim drive

Things to Remember:

  • Do not perform unknown changes to boot record or Master Boot sector as it may result to corruption issues
  • Always have proper backup of entire hard drive data on external storage components to avoid data mishaps
