Three passes and a full verify for every drive leaving your bench sounds like a lot of time burned on a problem that barely exists. Who's actually pulling tax returns off a used drive they bought? The skill and gear to run recovery on an overwritten disk isn't something some random buyer at a flea market has, lol. Your accountant drive test is a cool story but it's one drive, and testing recovery right after you wipe is about the easiest case there is. If cold hard proof of a wiped drive got pulled by a real attacker is out there I'd love to see it, because right now this feels like a lot of worry over nothing.

My bathroom sink drain was running slow for like 3 weeks and I kept putting off dealing with it. Finally grabbed one of those cheap plastic zip strip things from the hardware store for about 6 bucks. Pulled out this nasty black gunk that looked like a dead mouse, I almost threw up. Ran hot water after and the drain has been perfect for months now. Best money I ever spent honestly. Way better than dumping a bottle of draino down there and hoping for the best.
