Presence of a Removable Storage Device Might Prevent Converter from Successfully Converting a Physical Machine to an ESX Server Virtual Machine (1003042)
Remove any removable storage devices from the physical machine and wait 24 hours or set the credentials for the system to refresh the inventory before conversion. Setting the credentials with the same information that you have been using will still refresh the inventory.
To set credentials for the system:
In VMware Converter, navigate to the Analysis tab.
Right-click the system that you want to modify.
Select Set Authentication from the drop-down menu.
Enter the user name and password.
