NoDrive
Mine does it too. I have had every version of SW on it. It goes away after a minute or so, when it finds the drive. Leaving a zip plugged in with no disk, Turning off the other end of an ADAT or SPDIF device will also lock it.
Otherwise I love the VF16. It is a great multitracker for collecting 16 tracks at once and then doing a rough mix.
I am struggling with the result of the exported wave files not sounding as good after mix in Nuendo as they do out of the Fozzi. Man it makes the group sound just like they are playing in the room.
