Recovering a VMDK file can be tricky and risky as well. A VMDK file contains the entire data of a disk and any errors in the recovery process can lead to data loss. A VMDK file is the file extension for VMware Workstations and machines. Also, these types of files are prone to corruption. Recovering corrupt VMDK files is crucial to saving the entire disk data.

But when it comes to the selection of a method to recover corrupt VMDK file, there are not enough options available. However, we can perform a basic VMDK file repair with the manual method. Let’s check out how the manual process works.

Basic VMDK File Repairing Methods

1st Method:

If you’re unable to access the data of your VMDK file for the first time, then there are some basic repairing tips that can help you resolve this problem. Here is the detailed process to perform basic VMDK file recovery.

A VMDK file is basically a combination of two types of files, which include VMDK and *-flat.vmdk. The VMDK file works as a plain text pointer for the *-flat.vmdk. The (*) denates the VM server’s name. Whenever a VMDK file or VM server gets corrupt, the Virtual Machine fails to start. In such cases, the following steps can help you recover the VMDK file.

  • Create a backup copy of the original VMDK file.
  • Now, make a copy of the pointer file with a different VM to your system.
  • Make the required modifications to the fields and save the changes.
  • Boot the virtual machine to repair the VMDK file.

This process might seem easy to execute. But, the hardest part of this procedure is to get Cylinders, Heads, and Sectors precisely according to the size of the *-flat.vmdk file. Most users, especially beginners often fail to recover their VMDK file with this process and wonder how they can recover their VMDK file.

Well, there is another method to recover the VMDK file using command prompt in the Windows operating system.

2nd Method:

Using Command Prompt is also a great technique to recover VMDK files, but it is more suitable for technical users who have immense knowledge of cmd. Even if you’re a beginner, you can try to recover VMDK files with this method. Follow the below steps to recover the VMDK file with cmd.

  • Open the command prompt by pressing Window + R and enter cmd.
  • Now, go to the location of local installation of your VMware Dev kit.
  • Use this command in the cmd “vmware-vsdiskmanager.exe” – R “the fully qualified path to your corrupt VMDK.”
  • After typing the command hit Enter.

You might be able to recover your corrupt VMDK files using this technique, but this method also has the same limitations as the previous one. So, what is a secure and reliable solution to this problem? – use a third party VMDK recovery software.
