A search through data recovery forums like hddguru.com (they tend to have a secretive "trade union" attitude, but some useful stuff leaks through...) and the Internet reveals some more info like this: https://www.recoveryforce.ca/forums/viewtopic.php?f=12&t=157 Most of them seem to be head problems, and there are some outright head crashes too. Seems like bad media (leading to head failure) is mainly to blame: https:…

Huh. So many fixes in there are listed as 'replace head(s)'. I didn't realize that was a common fix for hard drives, thinking it would require near cleanroom conditions to ensure no dust got into the drive as its being worked on, and that it would be much cheaper/faster to maintain backups and swap in a new drive.

It's a "fix" in the context of data recovery business. The aim is to get the drive in a working condition for a few hours, just enough to get an image of it. After that the drive is trashed (or more precisely, put in a big box so it can be used as a donor for other drivers in future)

I've read that the replacement heads also often get damaged while reading the media during the recovery process.

Sounds like something you can solve with a labelmaker unless it's over the "do not cover" portions.

On the one hand, you can make 600-labels per rack. On the other hand, you could just buy WD hard drives at virtually the same price and not have to worry about those labels at all since the sticker is in the correct spot. Its not that its an unsolvable problem. Its that the solution is not worth the price difference between the drives.

You could put diodes next to each drive so the tech doesnt even have to read serial numbers.

Because of Big Santa (ie. parents). And that promptly fails when the cost of maintaining the Santa system gets too big (ie. as the child's mental faculties develop, plus as the child interacts with the outside world not controlled by the parents). So unless we all are living in a very well orchestrated NSA Truman show, it's unlikely that your argument applies.

That doesn't matter. Millions of adults orchestrate a secret conspiracy without any direct coordination even. The faculties of the target will only change the coordination and sophistication required.

If everything in the world were an illusion, I doubt that any group would be able to orchestrate that for all of us. But large groups can coordinate secret happenings, and they do, all the time.

Perhaps you should read Hogfather or Making Money by Terry Pratchett. In which the importance of the lies that society tells itself is touched upon. "All right," said Susan. "I'm not stupid. You're saying humans need... fantasies to make life bearable." REALLY? AS IF IT WAS SOME KIND OF PINK PILL? NO. HUMANS NEED FANTASY TO BE HUMAN. TO BE THE PLACE WHERE THE FALLING ANGEL MEETS THE RISING APE. "Tooth fairies? Hogfat…

Satirical fiction is probably not a great measuring stick to judge reality by.

Why not? Isn't that the whole point of satirical fiction?

> the pervasive belief in Santa Clause among children disproves your point No, it proves it. Default hypothesis: Santa is real. For Santa to be a conspiracy: my parents and all my friends’ parents must be lying to their children. Therefore: Santa is believed.

Would you care to elaborate on that logic chain?

Damn, I have a 12 disk RAID-Z2 with that, almost all of them failed in about 1~2 years, luckily because of Z2, I didn't lose any data. I'll never buy seagate again.

I bought a 500GB WD Green drive in 2010, and in 2011 I needed a second 500GB disk in a hurry. I went to a local supplier and all I could get was a Seagate 500GB disk. Oh well, beggars can't be choosers. I retired them both earlier this year, replacing them with a single 2TB WD Blue drive to augment my SSD. They are both still fully functional, not so much as a SMART error. I chalk it up to two things: The first is an…

Mine was in a home NAS server, almost never powered down, or moved, they die nonetheless, the replacement I bought, mostly TOSHIBA models, still works at this very moment, NONE of them failed.

Perhaps that's because you know the model number? When people browse the list of titles on the front mpage, they should know what the story is about. So, in this case, something like: "ST3000DM001 - A disk model number that would live in infamy" or: "Seagate's infamous ST3000DM001" etc.

There’s this aura of mystery and adventure to it. Who knows what it could be? It sounds like one of those sci fi wall-e tier robots.

I once replaced all of my friend's filing box labels with new labels, whose cryptic text had an aura of mystery and adventure. Strangely, my friend did not enjoy the adventure I had set him upon. If you know what I mean.

Every time a submission like this pops up I expect someone who worked at Seagate during that era to pipe up and explain what went wrong and why ... but I haven't seen it yet. Surprising.

I think it's sad that the hacker/maker community doesn't have enough knowledge/skill/inclination to disassemble this kind of thing and figure it out for themselves. It's a bad sign when tech complexity gets out of the expertise of a hobbyist - I believe that's the start of a stagnation of that technology as new young engineers never get excited about disassembling and modding hard drives in their free time, and in tu…

If you want to give it a go, I've still got a bunch of these drives lying around. We also have some still running in our zpool which I would gladly replace with something else, we're running out of space yet again... ;)
