Here is how you can perform a repair process on your corrupt VMDK:

Basically, a VMDK or a number of VMDK files is made up of 2 types of files:

  • VMDK And
  • *-flat.vmdk

VMDK is like a plain text pointer for the *-flat.vmdk and where the * denoted as the VM Server’s name. Because of some situation if a .vmdk file of your VM gets corrupt and you constantly failing to start the Virtual Machine then following the mentioned steps might help you recover Virtual Machine VMDK:

  3. Make the relevant modifications to the fields and save the changes.
  4. Now boot the Virtual Machine.

Method 2:

  1. Open the command line (cmd.exe)
  2. Navigate to the local installation of your VMware Dev kit  (mine is the default C:\Program Files\VMWare\Virtual Disk Development Kit\bin
  3. Type the following command “vmware-vsdiskmanager.exe” –R “the fully qualified path to your corrupt "vmdk”.
  4. Hit Enter
