RAD: Drive not saving contents on reboot

[10MARC]

I don't often use a RAD: drive, but I created a 13 Gig one today. It acts normally and data can be copied back and forth to it. But it does not survive a reboot like a RAD: drive should. Is this a known issue?
I am using a Pi3B in my A1200 with an Amigakit PiStorm.
