VMware Workstation powers virtualization for optimal system utilization. VMware Workstation uses virtual hard disks to simulate the storage capabilities of physical hard drives within virtual machines. Please see how to fix “Error 0xc1420117: The directory could not be completely unmounted“, how to Mount an ISO image in Windows 10 and 11, and how to install Windows Server 2022 on VMware Workstation(Opens in a new browser tab).

Solution

The steps below were relevant for my environment in order to resolve the issue depending on the version you are running.

Ensure that all the necessary libraries and dependencies required for mounting and unmounting virtual disks are installed and properly configured.

Also, Check if there is sufficient disk space available on the system where the virtual disks are located. Lack of disk space can lead to initialization failures.

Check the status of relevant services or daemons associated with virtual disk management. Ensure that these services are running without issues.

Ensure that all relevant software components, including virtualisation software or disk management tools, are up to date with the latest patches and updates.
