The virtual world is a vast and complex place. Within it are countless digital files that make up the fabric of its existence. Among these files are the virtual hard drives, or VHDs.

When a VHD becomes damaged or corrupt, it can result in data inaccessibility. The file may be damaged beyond repair, leading to permanent deletion from the virtual world.

Fortunately, there are experts who know how to repair corrupted VHDs. Let’s discuss what this VHD file is all about, its reasons for corruption, and how can you solve it using PowerShell commands locally on your machine.

Know About VHD File

VHD is a format for Virtual Hard Disk Drive. It is primarily used for backing up a system image. The data on your hard drive can also be stored in VHD. But a VHD file is vulnerable to corruption issues that make it unavailable to be used on a Virtual Machine. You can also remove a VHD from a virtual machine when it has fulfilled its purpose.

Reasons for VHD File Corruption

There could be many possible reasons for the corruption of VHD files, like:

  • Virus infection: It is a very common reason behind the corruption of VHD files. Once a system is attacked, it ruins files on the system, including the VHD files.
  • Failure of storage media: Due to corruption or failure of storage media, the files become inaccessible, and with that VHD file also gets corrupted.
  • Abrupt system shutdown: Accidental or sudden closure of your computer can cause severe damage to the software and hardware of your PC. Also, if the Virtual Machine is active at that moment, it may lead to the corruption or damage of the VHD file.
  • Paused state of Virtual Machines: If we do not notice the early signs of VM (Virtual Machines) failure or paused state of Virtual Machines, it leads to VHD file damage.
  • Due to human errors: Intentional/accidental deletion or removal of stored files, registry modification errors, force shutdown of the system, and improper disk management are some of the human errors that can damage VHD files.

Fix the damaged VHD File by creating a Virtual Server

Another way to fix a VHD file is by creating a virtual server. This method is very cost-effective also. Virtual servers are hosted on an operating system and are designed to share software as well as hardware resources. Without making any further delay, let’s learn how to do this:

  1. Start with creating a virtual server.
  2. Once created, connect a hard drive to it. You can add it by clicking on the Settings option.
  3. After the successful addition of the hard drive, browse the desired VHD file for further process.
  4. Once done, make a click on the Virtual Disk Wizard and select a Compact.
  5. Check the box next to Convert it to a fixed size virtual hard disk.
  6. Once you have performed all the above steps successfully, save the VHD file at the desired location on your system.

So, this is how you can fix a damaged VHD file with two different methods. There are possible chances that one of these two methods would work for you. But in any case, if none of them is providing you the results you desire, we would recommend you to read further.
