Module Disk Power On Failed – VMWare error – Solved

In the previous article, I have provided the solution for common VMWare workstation errors encountered during bootup. Here is an another common error “Module Disk Power On Failed” that I have recently encountered and you will find the workaround solution for the same.

Module Disk Power On Failed

I had a VMWare Windows 7 operating system image backup that I had created some time back, and I had copied it to one of the Windows 7 (64bit) machines. Later I installed the VMWare workstation player and tried to open my Windows 7 OS image via the “Open a Virtual Machine” option on the VMWare Workstation Player. The “Open a Virtual Machine” option opens the file dialog and requests for the .vmx (VMWare Configuration) file. I have selected the right .vmx file from the VMWare windows 7 OS image, and I receive the following error.

Failed to lock the file
Module ‘Disk’ power on failed.
Failed to start the virtual machine.

Further, I cleaned up .lck files from the virtual machine directory created earlier and tried to start the virtual machine. However still, the problem persists and fails to start the virtual machine.


Later I tried many other workaround options and tried to boot the virtual machine and hit the one workaround solution that worked for me.
I just opened Windows Explorer, navigate to the virtual machine folder where the VMWare windows 7 virtual machine image is located. I double-clicked on the .vmx file. That worked, and virtual machine OS booted up and started.

I had not done further investigation to find the real problem to see why the virtual machine is failed to boot up when the .vmx file opened through the file open dialog. You can try this workaround solution and leave comments if this solution is not working. I will update this post with the actual solution.
