NOTE that Western Digital runs a drive recycling program for EOL hard drives. They may not pay you money, but they do offer credits on new hard drives. Considering that China is constricting the availability of rare earth magnets now I think it behooves us to recycle these drives whenever possible.

There are third-party companies who undertake legally-binding contracts to erase all data on used drives before reselling them. A client of mine gets lots of drives from such a source. Here <https://shop.core.net.nz/products/lenovo-2ru-x3650-m5-rack-server> is an example of the sort of hardware he puts them in. That takes one or two expansion cabinets as well, for an extra 24 drives in each.

Umm .. CAUTION. That contract clause doesn't mean THEY can't pirate the drives BEFORE they re-sell 'em ! > A client of mine gets lots of drives from such a source.

HATE to waste those.

man urandom
When read, the /dev/urandom device returns random bytes using
a pseudorandom number generator seeded from the entropy pool. Reads
from this device do not block (i.e., the CPU is not yielded), but can
incur an appreciable delay when requesting large amounts of data.
My utility in pascal is faster than this, it does not wait.

Yep. Still use Pascal pretty often :-) >> Aside from that, I keep all my hard drives encrypted at rest. Now I do NOT worry about people physically stealing my drives. That's just RARE. The problem is online spies. In that situation you have already unlocked those drives and they are open to being read. Now corps who let people put sensitive data onto laptops they will leave on a park bench, THEN encrypted drives are a good, important, tact.

Some Mickey Mouse companies with > nothing worth stealing might... Physical destruction IS best. This can actually be as simple as a hammer or cold chisel. However the drill-press approach will also getcha there, esp if the drill also ruins the physical mechanism for read/write. Almost all drives these days have it in the SAME location. Good sharp half-inch drillbit ... TWO seconds to ruin the drive. Oh, while for a little while they made HDDs with glass platters, almost all are aluminum. Even a quarter-inch hole, followed by a small drop of toilet-cleaning hydrochloric acid (a pinch of salt added is even better) will absolutely ROT aluminum platters Real Quick. Used to keep a little vial of the brew. Anyway, unless you're the CIA or such, nobody is gonna disassemble yer old drives and try to run a "head on a stick" over them to try and recover bits of data. Defensive measures should be in proportion to the RISK. CIA probably MELTS the things. Joe's Garage does not need to - one good whack with a ball-peen will do it very nicely.

Well ... far more FUN !!! However the office manager wasn't gonna go for that ........ downer ! Oh, be careful with the 45-ACP, low velocity, has a tendency to ricochet. The .357mag is better IMHO :-) For awhile I had a high-voltage transformer meant for a furnace ignitor spark-thing. Little wire, would thunk it and turn on the transformer. Nasty sparks would then trash the chips on the disk control board. Didn't trash the platters alas, but made reading them a LOT more difficult for low-budget spies. OUR stuff wasn't worth the effort. Now likely cia/nsa have a furnace - a big pot of molten metal - and drop all their old drives into that. THEIR stuff IS 'worth it' for high-end hacks.

The office manager wasn't involved but the programming and QA staff had their yearly bonding operation out at the range. We even got the wimpiest QA guy to fire a gun. 'See, just like Star Wars!' We had everything from muzzle loaders to ARs. One of the women's father even showed up with a P08. I always lusted after one of those, well, just because... ' Si vis pacem, para bellum.'

There is no registration or permit required in this state so it's a guess but the estimate is 63% of the households have one or more firearm, often a lot more. They used to require a concealed carry permit for incorporated areas but we got rid of that restriction a couple of years ago. Open carry was always allowed except for a few places like the courthouse and bars.

People with 20/30/50 guns are not uncommon at all. BUT, note, such people almost NEVER do damage, likely to DEFEND the populace. It's the psycho lefties/illegals who are the threat. "Awww ...

Kneeling is a built-in response. SO sad. "Is this not better ? You were born to kneel !" - "Loki" character in "Avengers" movie.

We may not have guns but we have other ways... You joke at how many prime ministers have come and gone in Britain. People power. If they are crap the people get him sacked. The elite than choose another one. Who is equally crap. As I said 'after exhausting every other alternative' The problem with the EU is that it is/was profoundly antidemocratic. There was no way to prosecute , let alone sack the executive or the president(s). -- The New Left are the people they warned you about.

Some of what we did was after dark and if you had to plug a crack-head, well, you weren't gonna get fired for having self-defense. Latter bosses became more sensitive to lawsuit worries however ....
