Unable to overwrite files in Google Bucket from Windows

Again, not totally following. Are you saying not to run it as System account (which I am)? I just found this now which says not to run it as System because of the problem creating 4 folders at once (which I have).
And/Or
Should I be using -o uid=-1,gid=11 in the mount command (from the same article) to present the bucket as owned by the System account? Perhaps I should mention that I am mounting the bucket as a service in order for all users to access.
