If my three year old 350€ fridge has a no frost option that never failed or had hiccups in all that time, I assume the industrial one bought to store drives in that hypothetical situation would do to.

You can generally drench electronics as long as they aren't electrically loaded

Corrosion might be a concern but meh, wet for a moment doesn't matter. The drive forgets that part

If truly concerned, treat it like a slab of meat and put it in a bag
