Reverting a Formatted Hard Disk Drive (HDD): A Step-by-Step Guide

Understanding the Problem

A formatted hard disk drive (HDD) is a disk that has been intentionally formatted by a user, which means that the operating system has changed the file system structure, making it inaccessible to the user. This can happen due to various reasons such as accidental formatting, malware, or intentional actions. If you’ve formatted your HDD and now want to revert it to its original state, this article will guide you through the process.

Precautions and Preparations

Before you start the process, make sure to:

• Backup your data: Before attempting to revert your HDD, make sure to backup all your important files and data to an external hard drive or cloud storage.
• Disconnect the power: Unplug the power cord from the back of the HDD to prevent any accidental power-ons.
• Ground yourself: Static electricity can damage your electronics. Touch a grounded metal object or wear an anti-static wrist strap to discharge any static electricity from your body.

Step 1: Identify the Type of Formatting

To revert a formatted HDD, you need to identify the type of formatting it was done. There are two main types of formatting:

• NTFS (New Technology File System): This is the most common file system used by Windows operating systems.
• FAT (File Allocation Table): This is the file system used by older operating systems such as MS-DOS and Windows 95/98.

Step 2: Determine the File System Type

To determine the file system type, you can use the following methods:

• Check the file system label: Look for the label on the HDD, which should indicate the file system type.
• Use the built-in file system check: Open the Command Prompt and type chkdsk /f /r to check the file system.
• Use a third-party tool: Use a tool such as chkdsk or fsck to check the file system.

Step 3: Revert the Formatting

Once you’ve determined the file system type, you can revert the formatting. Here are the steps:

• NTFS (New Technology File System):

  • Open the Command Prompt and type chkdsk /f /r to check the file system.
  • If the file system is corrupted, you may need to run the chkdsk command again.
  • To revert the formatting, type chkdsk /f /r /u to unformat the entire drive.

• FAT (File Allocation Table):

  • Open the Command Prompt and type chkdsk /f /r to check the file system.
  • If the file system is corrupted, you may need to run the chkdsk command again.
  • To revert the formatting, type chkdsk /f /r /u to unformat the entire drive.

Step 4: Reinstall the Operating System

After reverting the formatting, you need to reinstall the operating system. Here are the steps:

• Windows 10 and later:

  • Boot into the BIOS settings and set the HDD as the primary boot device.
  • Save the changes and exit the BIOS settings.
  • Reinstall the operating system using the Windows 10 installation media.

• Windows 7 and earlier:

  • Boot into the BIOS settings and set the HDD as the primary boot device.
  • Save the changes and exit the BIOS settings.
  • Reinstall the operating system using the Windows installation media.

Step 5: Reinstall the Operating System (continued)

After reinstalling the operating system, you need to reinstall the necessary drivers and software. Here are the steps:

• Windows 10 and later:

  • Boot into the Windows 10 installation media.
  • Follow the on-screen instructions to install the operating system.
  • During the installation process, select the "Customize" option and choose the "Install Windows" option.
  • During the installation process, select the "Reinstall Windows" option.

Additional Tips and Considerations

• Use a third-party tool: Consider using a third-party tool such as chkdsk or fsck to check and repair the file system.
