USB Flash Corrupted Possibly after UPS initiated shutdown

Over the weekend I unplugged my UPS to do some cleaning. All systems were running off of battery normally. Based on my configuration (below) my Unraid initiated a shutdown after the battery levels/duration criteria was met.

 

However, when I went to turn the Unraid server back on, it booted to BIOS instead of Unraid. After further review, the computer couldn't see the Unraid USB Flash. 

 

I plugged the USB Flash into a Windows PC that stated it was corrupted. I used a data recovery tool to image the Flash and see if data was recoverable. For the most part it seemed I could pull most data of the drive, albeit it not gracefully.

 

I ended up formatting/reinstalling Unraid on the same USB Flash (new one ordered) and copied my /config over. The system came back up (based on the older backup I had).

 

Any idea why the USB Flash got corrupted? Any logs I can review?
