comment How reliable is a write protection switch on a USB flash drive?
So, a bit less specific version - would a read-only switch work as a reliable fail-safe mechanism when a write was not intended? Be it from malicious tampering with the live image or more probably just due to accidental erasing/overwriting when left mounted on another system.

Yes, in general this would help. But to be honest, when I look at the question now, I think my attack vector as described in its current state is purely theoretical and too specific. I also doubt any kind of attack would be that targeted. I should have described it as pertaining to the avoidance of unwanted data corruption.

That's in fact my assumption I'm trying to confirm. As to SD cards, I've added an excerpt from SD specifications showing that mechanical switches are explicitly host based. Only internal card protection would work, but it's not that common (optional to the standard). But I suppose it's this kind of internal solution that is used on flash drives, however I couldn't find anything precise about it.
