Fix disks appear as portable devices on VMware VM

Nothing is wrong with your Windows Server configuration, and everything is set correctly. But it has to do with the VMware Virtual Machine (VM) configuration settings.

To remove the HotPlug capability on removable devices and have the warning go away, you will need to add a parameter to the Virtual Machine configuration by following the below steps:

  1. From a web browser, connect to the vSphere Web Client.
  2. Log in with Administrator credentials.
  3. Navigate to the virtual machine you want to modify.
  4. Power off the virtual machine.

Important: You must power off the VM and apply the parameter in the configuration. A VM reboot is different, and the change will not apply. Once the parameter is set, start the VM.

  1. Right-click the virtual machine and select Edit Settings.

After the VM starts, open the Device Manager and verify that the Portable Devices section is not present anymore.
