Re: Shutting Down a Robot-Mounted Pi

/sigh. No computer system that I've used from mainframes to Raspberry Pi, from MCP to Unix, including Windows and Linux deals well with hard power off when there are IOs in process. You've been lucky.

Lots of people have borked the SD card in a Raspberry Pi. The OP asked a good question, and people are trying to help. Your "whistling in the dark" isn't productive and I predict that someday you will either spend the night hand sewing inodes to restore a file system, or spend most of the day hoping your backup system really works while you boss yells at you about lost orders.
