I have a Roku 3 and I recently bought a micro sd card from Roku. I inserted the card and it was recognized after a pause. When it came to formatting, it got to 5% and then seemed to stick. Eventually I got a message telling me “this micro sd card could not be formatted”. I took it out and tried again. This time when I pressed “continue” the little circle just kept going around. Now I can’t even get the sd card to be recognized. I have tried when the Roku is fully booted up and before booting up. No success. Any solution? I am surprised that Roku would supply a card which results in a message saying that particular card cannot be formatted!
Try formatting the card in your computer, if it has a card reader that can handle SD cards. After formatting, see if the Roku will detect and reformat the card successfully.
Windows instructions, don't know what would differ on other systems:
Do a slow (i.e. not "fast") format of the card via your computer. Be sure to select FAT32 and select it to use the default allocation size.
