About DiskPart virtual disk service error

The Virtual Disk Service is provided by Microsoft Windows and, upon request from its clients or applications, executes commands, and configures the necessary system parameters. These actions are carried out using the DiskPart command, and thus the end-user can manage hard disks, volumes, etc.

However, sometimes the DiskPart virtual disk service cannot complete the task and gives an error; for example, “virtual disk service error cleaning is not allowed on the disk containing the current download”.

This situation can occur while formatting a disk to the FAT32 file system, while cleaning up a disk, deleting partitions, converting a GPT disk to an MBR disk, etc.

Depending on what error occurred in the DiskPart virtual disk service, there are different solutions, which will be discussed in this article.

How to fix “The specified disk is not convertible” error

This error appears when converting GPT or convert MBR and can be fixed with Disk Cleanup. You need to delete partitions before converting the disk to GPT or MBR using the DiskPart convert command. Before this step, you should back up your data to any external hard drive, as the data will be lost.

To open DiskPart, type “cmd” in the search bar. Next, right-click the Command Prompt result and select "Run as administrator".

In the new window, type diskpart and press Enter.

Next, you need the following commands:

  • list the drive and press Enter.
  • select disk 1 (replace 1 with the target disk number) and press Enter.
  • clean and press Enter.
  • convert GPT or convert MBR and press Enter.
  • exit and press Enter.

How to fix “There is no media in the device” error

This error indicates that DiskPart cannot find the specified media. That is, DiskPart could neither download nor access the device.

In such a case, you can proceed as follows:

  • Try plugging the media into a different USB port to reconnect the external storage device or reinstall the hard drive / solid-state drive.
  • ry updating the device driver without media. To do this, right-click on "This PC" and select the line "Management". Next, open the Device Manager tab and expand Disk Drives. Find and right-click the problematic device and click Update Driver. Then select the function "Search automatically for updated drivers'' and wait until the device driver update is completed.

How to fix “The service failed to initialize” error

If the virtual disk service does not start automatically on a Windows PC, you may receive this error. This indicates that the initialization went wrong. To fix the problem, do the following:

  • Type “cmd” in the DiskPart search bar and click OK. Next, right-click the Command Prompt result and select "Run as administrator". Then type net starts VDS and press Enter. This should fix the service failed to initialize error.
  • You can also try restarting manually the virtual disk service. To do this, type “services” in the search box and press Enter. Then select the result "Virtual Disk" with the right mouse button and click "Start". This will change the startup type of the virtual disk service from manual to automatic and restart Windows.
