Raspian For Robots

The Raspian for Robots SD card will not run. We get an error that says “Not syncing”. This is only the second time we have used the SD card. Suggestions?
Thanks!

My suggestion is to plug the sd card into your computer and get any files you need off and redo the card following these instructions:

That’s the easiest way.
