My observation is that crappy RAID, when it fails, can mimic a HD failure, by randomly nuking and/or rearranging sectors. I came to this conclusion after doing a massive extraction on data scraped from a "failed" RAID array. Turns out the data was almost all there, but randomly rewritten all over the place. Far as I could tell from the data, nothing wrong with the HD (failing HD makes a different sort of garble). But it was called a HD failure by the server's owner.
My first real computer (a 286 that I finally retired for good in 2001, tho I still have it) has an ST-225. Ran hot, slow, and needed a fresh low-level format every couple years, but the durn thing still worked. You could tell exactly what it was doing -- seek, read, write, and delete were four distinct sounds. Unrecognised sounds were a sign that a LLF was in its near future.:(
I've had about the same experiences, probably covering a couple hundred HDs. Maxtors die early and often and with no warning; Seagates tend to die of bad bearings (sudden overheat death syndrome) tho not so often as Maxtor; WD last a very long time, and give a lot of warning before going tits-up. I have a bunch of WDs with over 10 years on 'em, 24/7.
When Seagate bought Connor they just relabeled the crappy Connor drives that came with the deal and sold 'em as Seagates, but the firmware still reported as Connor, and still had the same issue (extended time powered off == lost data).
As I recall the whole story (from the book on the history of DRDOS, which had some details I've not seen elsewhere, including the relevant code snippets) was that Windows had issues with DRDOS *due to a bug in DRDOS*, tho MSFT took advantage of it.
I used DRDOS7 for years, and it did take some jiggery-pokery to get it to play nice -- Windows wasn't much of an issue (I never had a bit of trouble with Win3.x over DRDOS) but any DOS app that used a protected-mode memory manager required its own config settings. Notably it was ill-mannered with DOS games.
Once M$DOS7 was available, my DR/NWDOS went, uh, out the window. It had its good points but overall it was too much trouble, and it was noticeably slower.
I've lived in Montana, and in southern California. Speaking from experience with the contrasting styles of gov't and enforcement, I'd say you've about nailed it.
Mmm, I used a regular wood stove (nothing special, just a firebox and flue) in a house that was very well insulated -- I only had to heat or cool it about every 3rd day, year round. The walls had been redone, but I think the real key was the 1950s foundation slab -- guy didn't know what he was doing, so he just dug a hole and filled it with concrete -- it was about 3 feet thick. Huge heatsink for the whole house.
Vague anecdote -- I'd go thru about a cord of wood a month, or 80-100 gallons of propane. Even at retail for firewood of around $130/cord delivered, that beats retail for propane at $3.35/gallon.
[Tho I always cut my own, and the source was free scrap that I'd pick up on my way home, so it cost me a few hours with the chainsaw and a quart of gas.]
No, they won't go door to door inspecting every rural home, but mark my words, it WILL be used to selectively condemn property, much as the "oh no you don't have a building permit" (even tho none was required) crap that's going on in Los Angeles County.
And in rural areas, the question isn't just wood heat vs some other fuel; it's often wood heat vs NO heat, because the alternatives are too damned expensive. (Frex, propane, which can be as bad as $3 every ten MINUTES.)
One suspects some very selective measurements (perhaps inside the firebox) have been made to ensure that a certain segment of the population can't afford heat, thus adding them to the welfare rolls. And we all know which way =those= folks vote.:/
And what would happen to home heating costs without wood-burning stoves?
I can tell you from living in a cold climate... the difference was keeping the house at 40F degrees (yes, you read that right) at the price of propane, or comfortable at the price of wood.

HSUS is, bluntly, a money laundry based on the animal rights schtick. Since one of the AR goals is no more pets, making pet deaths as ugly and expensive as possible is seen as one way of reducing pet ownership.
My mom has that same trait I've seen in films of wild monkeys -- if she sees a snake, ANY snake, she immediately screams and points and jumps onto the nearest raised object. It's hardwired, totally instinctive reaction on her part.
I react the other way around -- if I see a poisonous snake, I instantly go into hunter/killer mode, and woe unto the rattlesnake that crosses my path.

I seem to recall it's not the reallocated sectors that's the issue, but whether that's successful or not. If not... run to store. Do not walk.

The EPA won't, but local code enforcement will. As you say, any new pretext...

I did wonder how many of these modern efficient stoves require electricity to operate. (Most pellet stoves do, regardless of efficiency.)
Older ones are mostly owned, not rented. And at the price of propane... probably sitting empty.

Well, here's the questions that came into my head:
How is a password, generated for your employer, any different from any other work-for-hire?
How is a password, generated to inconvenience your employer, any different from any other sabotage?

So to prevent bad things, one winds up with a worse thing! :(
