This is kind of strange - I pulled a couple of drives off of my Pogo for local re-working of many files - put them back on the then the Pogo came back named "Pogoplug" only, in Finder/Shared/
Bonjour.  My drives were not showing up.

The previous name was "fadsxxxxxxxxxx"

I figured it was maybe trying to rescan them - so I turned everything off for both drives in Media Settings -

Stream - Disable

Optimize - OFF

Create - OFF

Generate - OFF

Double checked WFS and it was still running as before.

Eventually, Pogoplug and fadsxxxxxxx both appeared and my drives were available again (under fadsxxxxxxx)

Ultimately the name "Pogoplug" went away in the list, getting back to where I was before.

Not sure what happened exactly, but the best way to get up and running fast apparently is to turn OFF all the items in Media Settings.... but you still have to wait for something.
