Proper Jevois Shutdown? (Without unplugging)

We have been experimenting with the JeVois vision system and are getting frustrated with having to replace all the corrupted SD cards that come from shutting it off/unplugging it repeatedly. There has to be some way to avoid this, but we haven’t found any info on how to properly do this. Our worry is that this would happen when we shut the robot off or if the robot went dead on the field. Has anyone else experienced a similar issue?

This might help you but I have not tried and I do know the JeVois is odd when it comes to USB power.
