... some vendors have been found tampering with SMART data which can be done on certain models ...
In the post-chia[1] landscape, I would advise extreme caution in sourcing drives and a decent shortcut is to not buy from Amazon ...
Anything could be on there
edit: of course who knows what's on the hardware, but I haven't heard of the exploit that would doom me.
Some of those chips are straight up salvaged from other electronics. Some are "known bad" chips, hanging in by a thread while the flash controller is fighting to sweep all the bad blocks under the rug. Some are dead MicroSD cards - with the dead MicroSD controllers bypassed to access the NAND die directly.
NAND flash chips are "everything but the squeal" of electronics. There is a lot of chips that "somewhat work", and a lot of people trying to "upcycle" them into something that works long enough to be sold.
Rather, it is a combination of a highly intensive use case and a relatively morally bankrupt user base that results in a supply chain full of burned out SSDs.
I say relatively morally bankrupt… I am sure there are many delightful people out there mining Chia coin …
Barring that "evil twist", they'd not be doing anything all that uncommon/illegal but refurbished hard drives and the companies that sell them have been a bit scammy/"buyer beware" hardware for as long as I can remember.
Back in the early 90s, I spent a year saving up for and building the best 486 PC I could buy. I went with a 330MB[0] SCSI drive that I picked up from a small magazine advertisement in Computer Shopper. They advertised it as refurbished, and there was no such thing as SMART parameters to reset (were there even counters of any kind back then, I can't remember?) so there was no way to tell how long it had been used except for the price. These were more than half off.
It seemed shady, the price was still several hundred dollars (though, I want to say something like $500 off of the cheapest new option) and being a dumb teenager, I called the number and placed the order.
My heart sunk a bit when it arrived. If memory serves, this was the one that came with all but one of the threaded screw slots completely stripped (of the four I needed to use given my case). Technically, they were all stripped, but one of them still had the screw -- left behind, evidently, because it became welded to the hole.
After some delicate work with a metal file, I got it all installed and nothing worked. So I called the manufacturer who took about ten seconds to find the problem: That's a Differential SCSI drive. It took another few minutes for him to explain what that meant. There was no mention of this in the advertisement (they didn't even include the model number, just "330GB SCSI DRIVES!" I think these were common in AS/400s or something along those lines.
fsck.
So ... I bought a differential SCSI controller, cable and terminator, which set me back more than half of the savings from the drive. Because, as a teenager, I hadn't learned about the sunk cost fallacy.
I hadn't appreciated, then, what a miracle it was that when everything was plugged in correctly, it all worked and continued to work until I upgraded the drive. The thing was extremely loud (occasionally making a unique sound similar to when wood hits a circular saw, like the magnetic head was grinding off some of the platter -- given its size, it had plenty of room to chisel the bits onto the surface ...). It was a massive heat source for not just the case, but the room. But it served my stupid BBS for several years, somehow.
[0] It's been so long, I may not have that capacity right. It was 3-4 times what was typical at that time (I ran a BBS with file"z"). It was a 5.25" drive that required a full height slot (it was about 3/4 full height) to give you an idea.
I assume that was the original business this outfit was involved in, anyway, since most of those companies are shady, already. :)
I remember being in a computer store, and this woman was being told she should buy a 2x SCSI CDR, rather than the 8x IDE one she'd been eyeing (plus controller and cables, etc., of course), "Because SCSI is a much better interface and performs better so the two-speed drive will be faster than the eight".
I couldn't let that go, waited til the sales guy stopped buzzing, and told her the truth of the matter, and showed the specs... 300KB/s versus 1200KB/s has nothing to do with the interface. Yeah, the bus or whatever might be more performant (and do its own controlling, versus offloading), but immaterial.
An 8x SCSI drive would be preferrable to an 8x IDE drive, but he was obviously trying to sell what thought he could unload with that half-truth.
I know even long after IDE was mainstreamed, cost-no-object builds (think Boot/Maximum PC's annual Dream Machine) would have SCSI for reasons like that.
I know I went with SCSI, originally, because I had actually purchased two drives -- the huge one, and another one that was a bit faster but smaller and something had led me to believe that SCSI lent itself better to that configuration. I can't remember, specifically, what though.
I recall with CD-ROM drives -- earlier ones -- it was similar. Actually, in a few ways it was worse because the earliest CD-ROM drives came as SCSI or "Parallel Port to SCSI" which I'm not sure anyone ever got to work completely right.
But ... and I could just Google it but I'm being lazy ... I recall it had something to do with Bus Disconnection and Native Command Queuing in SCSI that allowed the CD-ROM drive and the HDD to operate without waiting on one another (as much?).
I know SCSI drives basically disappeared once IDE drives became common. You didn't see SCSI controllers often outside of servers, ever, in the PC world except for a brief period when that was the most common CD-ROM drive.
The writer waited his entire life for this moment xD
I would have missed it if it weren't for your comment.

Thank you, Bert Healy.
Or is it even more clever than I can parse?
Could be criminals are spilling the beans by writing down confessions. (I don't know the original intent.)
And organized criminality is unlikely, more or less ewaste recycler got a ton of hdds, wants to maximize, hired people to do the physical and not be around. If that’s organized criminal activity akin to how the writer described it.. eh it’s really weak.
More fraud happens on eBay daily and I haven’t heard any of this go down in the USA …
But yeah resetting smart values bad.
To write as if it’s the next cartel driven industry, no.
