All of the data was read-only, regardless of what adapter we put it in (we tried like five different ones). So you could retrieve the data that was baked onto it, but formatting the card was a lost cause.

So getting it to format was like trying to pull Excalibur out of the stone!

the joke became that as we explained the futility of formatting the SD card to any new person, they'd instantly think "oh no, they probably haven't tried x, I bet I could do it" and try it and fail in a similar fashion to how everyone thought pulling excalibur from stone would be an easy feat, but trying it, they failed
