Vmware Workstation - Cannot open disks xxxx or one of the snapshot disks it depends on

I'm running Centos7 using Vmware workstation on windows 7 laptop. All was well until I restarted my laptop this morning & my VM started complaining as below

The parent virtual disk has been modified since the child was created. The content ID of the parent virtual disk does not match the corresponding parent content ID in the child

Cannot open the disk 'C:\Users\<user>\Documents\Virtual Machines\CentOS 64-bit\CentOS 64-bit-000003.vmdk' or one of the snapshot disks it depends on.

Module 'Disk' power on failed.

Failed to start the virtual machine.

Below is the image of the folder containing the VM & the image of the VM itself.

I've looked through the vmware log & found the disk ID

Vmware workstation error

Solution

  • All you have to do is to delete the .lck file from the folder of your vmdk files. It is generally present at C:\Users\UserName\Documents\Virtual Machines\VMWareName

    Also you can just move the lck files one folder up to ensure you do not delete any other file by mistake.
