Look, I don't need full drive failure for this to happen. I can just

Given that all events are under my control, statistics make little

I recommend a sledgehammer.

If you want to lose your data, you might as well have some fun.

No need to bore yourself to tears by simulating events that are
unlikely to happen simultaneously to careful system administrators.
