Overview of VHD Corruption

Virtual Hard Disk v2 and VHD (Virtual Hard Disk) are file formats representing virtual hard disk drives used with virtual machines. These formats are commonly associated with Microsoft's Hyper-V virtualization platform and are essentially containers that store the contents of a virtual machine's hard disk drive.

Corruption in VHD files can occur due to various reasons, leading to difficulties in accessing the virtual machines. Here are some common causes and characteristics of VHDX/VHD corruption:

• Improper Shutdowns: If a virtual machine or the host system is not shut down properly, it can lead to corruption of the VHD file. This can happen due to power failures, system crashes, or abrupt termination of the virtualization software.
• Hardware Failures: Issues with the underlying hardware, such as bad sectors on the physical hard drive where the VHDX/VHD file is stored, can lead to corruption. This is especially true if the hardware issue affects the parts of the disk where the VHD file is located.
• Virus or Malware Attacks: Malicious software can corrupt or modify the contents of VHD files, making them inaccessible or unusable.
• Software Bugs or Incompatibilities: Bugs in the virtualization software or compatibility issues between different versions can lead to file corruption. This can occur during operations such as migration, cloning, or conversion of virtual disks.
• Network Issues: If the VHD files are stored on network-attached storage or are being accessed over a network, network interruptions or errors can cause file corruption, especially during data transfer operations.
• Human Error: Accidental deletion of critical files related to the virtual machine or incorrect modifications to the VHD file structure can result in corruption.
• Fragmentation and Over-provisioning: Excessive fragmentation of the VHD file or over-provisioning of storage space can lead to performance issues and potential corruption.

To prevent VHD corruption, it's important to maintain a stable and secure computing environment, ensure regular backups, use reliable hardware, and keep virtualization software updated. In case of corruption, specialized recovery tools or techniques may be required to retrieve data from the corrupted VHD files.

Where are VHD files stored?

VHD files are stored on the host machine or storage device that is running the virtualization software.

In a typical virtual machine setup, the VHD file is created and stored on the physical hard drive of the host machine or on a network-attached storage (NAS) device. The virtual machine software then maps the VHD file to the virtual machine as a virtual hard disk.

In cloud computing, VHD files are typically stored in a cloud storage service provided by the cloud provider, such as Azure Blob Storage or Amazon S3. The cloud provider's virtualization software then maps the VHD file to the virtual machine running in the cloud.

How to Recover Deleted VHD file

Recovering deleted VHD (Virtual Hard Disk) or Virtual Hard Disk version 2 files involves several steps and can be achieved using various methods. The approach to recovery largely depends on the circumstances of the deletion and the availability of backups or recovery tools. Here's a general guide on how to recover deleted VHD files:

1. Check the Recycle Bin

• First Step: If the deletion was recent and you haven't emptied the Recycle Bin, the VHD file might still be there. Check the Recycle Bin and if you find the file, right-click on it and select "Restore".

2. Use File Recovery Software

• Specialized Tools: If the file is not in the Recycle Bin, you'll need to use file recovery software, like DiskInternals VMFS Recovery.
• Scanning Process: Run a deep scan with the recovery software on the drive where the VHD file was stored. This process might take some time depending on the size of the drive.
• Recovering the File: Once the scan is complete, look for your VHD file in the list of recoverable files. Select it and choose a safe location to save the recovered file (preferably a different drive).

3. Utilize Backups

• Regular Backups: If you have a regular backup system in place (like Windows Backup or a third-party solution), check your backups for a copy of the VHD file.
• Restoring from Backup: Follow the specific procedure provided by your backup solution to restore the VHD file from the backup.

4. Use Previous Versions (Shadow Copies)

• Windows Shadow Copy: Windows creates shadow copies that can sometimes be used to recover deleted files. Right-click on the folder where the VHD file was stored, select "Properties", go to the "Previous Versions" tab, and see if there are any restorable versions available.

5. Contact a Professional

• Data Recovery Services: If the above methods do not yield results and the data is critical, consider contacting a professional data recovery service. These services can sometimes recover data when all other methods fail, but they can be costly.

Tips for Successful Recovery

• Stop Using the Drive: To avoid overwriting the deleted file, stop using the drive where the file was stored immediately after deletion.
• Choose a Different Drive for Recovery: Always recover the file to a different drive to prevent overwriting other lost data.
• Regular Backups: Implement a robust backup strategy to avoid data loss in the future.

Remember, the chances of recovery depend on how quickly you attempt the recovery after deletion and whether the space on the drive where the VHD file was stored has been overwritten or not.
