My Refined Storage system ran out of power and when I turned it back on their was not items in it but the storage still says their is
did you try replacing the storage drive(the block)? also is it connected to the terminal you are using? it might not have enough power, it might still light up, but wont work
Can you create a new Refined storage system? Take out the disks and use a new drive and controller with a terminal. See what happens.
