I don't think the reformat had any effect.

The times I've seen a robot move while disabled, it has been due to a PWM cable that would periodically short, resulting in a very short PWM glitch. I've almost always seen it with Y cables. If you carefully mash on the Y of the cable, you will see the occasional burst from the controller. Rolling it in between the thumb and finger was the most reliable way to make it happen.

I have also seen it in a robot that was shorting power and causing the motor controllers to reboot. On power up, the controllers would glitch and reboot again, rinse, repeat.

I have never seen this with a CAN controller. I'd like to hear details.

Reformatting the RIO is equivalent to formatting the hard drive on a linux computer. It is necessary when you have a corrupted file, which shouldn't really happen, and it is necessary at the beginning of the season to install a new set of files.
