I just plugged a new SD Card into my Roku 3. While the SD card is plugged in, I don't think Roku sees it or gives me any sort of prompt to format the card. What Roku screen do I need to go into to make the Roku format the card? When I go into the settings-System-about screen, it says SD Card not installed.
It should recognize it automatically and offer to format it. Make sure the card is fully inserted. You have to push it in with a fingernail or something to get it to click into place. It should not be sticking out of the little slot at all once it's fully inserted.
