It just might work out.
I get the impression putting WD on a USB stick was only intended for one-off use. Although the method of determining the update state is messy for a portable, I guess it might not be so bad if you could find a way of getting the updates on there which you were eventually able to trust without checking each time.
Always pop back and let us know the outcome - thanks
