I get the same message on the Xperia Z3+ after Mashmallow update.
Think its just saying it can see the SD Card and it's using the old system.
Again, the message you get when you boot/restart your phone is normal with the Marshmallow update. What most of us on this forum are suffering from is the random and unexpected dismounting of the card, which results in the annoying notification.
