Solved – VMDK is Corrupted and Cannot Be Repaired

VMware’s Virtual Machine Disk (VMDK) files are integral to storing the complete data of virtual machines. When these files become corrupted, it can lead to significant data loss and disrupt virtual environments. Addressing VMDK corruption promptly is crucial to maintaining system integrity and preventing permanent data loss. In this article, we delve into the common causes of VMDK file corruption and provide effective methods to repair and recover VMDK is corrupted and cannot be repaired.

What makes VMDK File Corrupted?

Understanding the root causes of VMDK file corruption is vital for prevention and effective recovery. Common causes include:

  • Missing Descriptor File: The descriptor file contains metadata about the VMDK. If it’s missing, the virtual machine may fail to power on, displaying errors like ‘Failed to power on. A file was not found.’
  • Incorrect Descriptor in VMDK Flat File: Errors in the descriptor section can lead to miscommunication between the virtual machine and the VMDK, causing startup failures.
  • Corrupt VMDK or Flat File: Damage to these files can result from various factors, rendering the virtual machine inoperable.

Other reasons for VMDK is corrupted and cannot be repaired

  • Virus Attacks: Malicious software can corrupt VMDK files, making them inaccessible. It’s essential to maintain robust antivirus protection to mitigate this risk.
  • Unexpected File Closure: Abruptly closing files during the saving process can corrupt VMDK files. Always ensure files are properly saved before closing.
  • Forced System Shutdowns: Sudden power failures can abruptly shut down systems, corrupting open VMDK files. Utilizing an Uninterruptible Power Supply (UPS) can help prevent such incidents.

There are several other reasons for VMDK File corruption but I have considered the known ones because in the majority of corruption cases these three reasons are common. I have discussed a lot about the causes now let us move directly to the topic that how to fix VMDK is corrupted and cannot be repaired the issue.

How to Solve “VMDK is corrupted and cannot be Repaired” error in VMware?

Method 1: Use VMDK Recovery Utility

By using VMDK Recovery software one can quickly recover corrupted VMDK files. Using this tool you can recover the maximum amount of corrupt data. It is a direct method, not a time-consuming process, like that of manual methods. It’s always recommended to be the best choice first. Some important steps to download it are given below:

  1. Firstly, Launch VMDK Recovery software and then choose the disk type. After this hit Browse >choose the corrupt VMDK file. Press Next.
  2. Next, either select standard or advance mode and then if the partition table is saved in GPT format define it and choose other options as well. Hit next.
  3. Pick the volume from which you want to recover data. To define the custom settings for selected volume recovery check Custom Settings for selected volume box. Hit Next.
  4. Now, you can choose the recovery mode either Standard, Advanced or Deep. Suppose if you select an advanced mode then define the max file systems to find. Press Next.
  5. The selected volume will be scan within a few seconds. Hit OK.
  6. To check the preview of data click files and folders listed in the tree structure. Then choose all the data that you want to save and press Save.
  7. Choose a path for saving the selected files and folders. Hit OK to start the saving process.

Method 2: Create a Backup

Maintaining regular backups is a proactive measure against data loss. If a VMDK file becomes corrupted, restoring it from a recent backup can be an effective solution.

Steps:

  1. Locate the Backup: Identify the most recent backup of the original VMDK file.
  2. Create a Copy: Duplicate the backup file to ensure the original remains intact.
  3. Replace the Corrupted File: Substitute the corrupted VMDK file with the backup copy in the virtual machine’s directory.
  4. Boot the Virtual Machine: Start the virtual machine to verify that the issue is resolved.

Method 3: Using a Command Prompt

Using Command Prompt is also a good technique for recovering VMDK files, but it is more appropriate for technical users with immense cmd knowledge. Even if you’re newcomer, use this tool to recover VMDK files. Follow the steps below to recover the VMDK file:

  1. Hit Window + R to open the command prompt and then enter cmd.
  2. Next, move towards the path of the local installation of your VMware Dev kit.
  3. Use this command “vmware-vsdiskmanager.exe” – R “the fully qualified path to your corrupt VMDK” in cmd.
  4. At last, press Enter.

But these two manual methods have the same limitations, such as a time-consuming process, low speed of execution, etc. So, choose the software to be the best option first.

Bottom Lines

Corruption of VMware file is a reason for stress. Technically speaking, some professional tools can solve “VMDK is corrupted and cannot be repaired” problem. If you experience problems of damage, inaccessibility in VMDK data or problem of deletion of files & partitions, VMware recovery software is ready to help. This versatile software has been specially designed to restore all your data easily and quickly from the VMDK VMware Virtual machine.
