Corruption of VHD files can lead to loss of essential files and folders including the boot files. 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 to VHD. But a VHD file is vulnerable to corruption issues that make it unavailable to be used on a Virtual Machine.
Try Kernel for VHD Recovery, an automated tool to repair and recover all types of files from corrupt or damaged VHD/VHDX partitions in a single attempt.
Reasons for VHD File Corruption
There could be many possible reasons for corruption of VHD files, like:
- Virus infection: It is a very common reason behind corruption of VHD file. 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 software and hardware of your PC. Also, if the Virtual Machine is active at that moment, then it may lead to the corruption or damage of 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.
How to repair a damaged and corrupt VHD file?
As we have discussed a bit about VHD files and the reasons for corruption and damage in a VHD file, now let’s move towards the solution. As we have studied and researched, we have come up with the two best solutions to deal with this scenario. Have a look at the solutions and the processes mentioned below:
Repair Your VDH File Using PowerShell Commands
Many VHD repair methods can be performed to restore your virtual hard disks after corruption issues. Here, the commands used to scan and restore the VHD file are explained one by one.
- Command to scan an image for corruption
- Command: Dism /Online /Clean-Image /CheckHealth
- Description: This command scans the file completely to check for corruption.
- Command for checking an image for corruption
- Command: Dism /Online /Cleanup-Image /ScanHealth
- Description: This command will check whether the image file is corrupted or not and will specify whether it can be repaired or not.
- Command for repairing and restoring from corruption
- Command: Dism /Online /Clean-Image /RestoreHealth
- Description: This command will automatically perform the repair if it finds corruption.
Fix the damaged VHD File by creating 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:
- Start with creating a virtual server.
- Once created, connect a hard drive to it. You can add it by clicking on the Settings option.
- After the successful addition of the hard drive, browse the desired VHD file for the further process.
- Once done, make a click on the Virtual Disk Wizard and select a Compact.
- Check the box next to Convert it to a fixed size virtual hard disk.
- 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.
