How to recover data from corrupt VMDK file

This blog gives various methods on how to recover data from corrupt VMDK files. If you are searching for it, then you get to read on about its resolutions.

We are living in a world defined by boundaries. But, there is another world that is the Virtual reality to connect with users without restrictions of boundaries. This virtual world works on a Virtual Machine (VM). It corresponds to a computing resource that uses software instead of a physical computer to run programs and deploy apps. So, VM allows you to run an operating system in an app window on your desktop that behaves like a full, separate computer. 

Let us get to know better about the VM files called the VMDK files.

What is Filename.VMDK?

It is a virtual disk file, which contains the contents of the virtual machine’s hard disk drive. It is made available by VMware products. A virtual disk consists of one or more .vmdk files. The increase or decrease in the number of .vmdk files depends on the size of the virtual disk.

Previously VMware products used the extension .dsk for virtual disk files. VMDK data is supported by Virtualbox, QUMU, and XVM, among other virtual machine applications.

What happens when all the information about the virtual machine on the VMDK file is damaged or becomes inaccessible? Read further to know how to recover data from corrupt VMDK.

A combination of two types of files, namely-VMDK, and *-flat.vmdk, form a VMDK file. The plain text pointer is contained in the VMDK file for the *-flat.vmdk. The VM server name is denoted as (*). Whenever a VM server or VMDK file gets corrupt, the Virtual Machine fails to start. In such a scenario, the following steps can help you recover the VMDK file. 

  1. Firstly, make a backup copy of the original VMDK file.
  2. Secondly, make a copy of the pointer file with a different VM to your system.
  3. Thirdly, do the required modifications to the fields and save the changes.
  4. Initiate the virtual machine to repair the VMDK file.

This process seems like an easy task. But, it is the hardest job to get Cylinders, Heads, and Sectors precisely according to the size of the *-flat.vmdk file. Beginner users often feel confused and fail to recover their VMDK files with this process.
