I have a stock 500GB internal drive and a USB3 500GB drive one my Xbox One.
Until this week they showed as a combined available/used space in the apps dashboard and games where automatically installed across both drives, this has now stopped and the drive are displayed as individual drives.
Has anyone else come across this issue? I've searched a few forums with no hits.
BTW I've already switched the unit off and on and disconnected the drive and reattached.
