To straighten up things, I would go ahead, delete all snapshots, move the "/Users/danhair/Virtualbox/Go Fast/Go Fast.vmdk" file(s) to the VM's "Go Fast.vmwarevm" folder and edit the .vmx file (with Fusion closed) to point the virtual disk to this file.
ide0:0.fileName = "Go Fast.vmdk"
Are there other files in the VirtualBox folder for this VM too?
