operating temperature, storage temperature, humidity, age (manufactured in 2010) on 2.5" and 3.5" HDDs all cause long term demagnetization and bit rot of these HDDs?

No. Thank you.

What causes the demagnetization of 2.5" HDDs? Is it inevitable?
Here where I live it is impossible to control the temperature and humidity, which varies from 34-36C 58-67%

some answers yes, some no, which one is true? which one to trust? that's why I asked here where there are more experts in the HDD area

Do 2.5" HDDs become demagnetized in the long term due to high temperatures and high humidity in the place where they are stored?
For example, in my case, 34-36C humidity 58-68% and the oldest HDDs I have were manufactured in 2010, the others in 2016. I don't use them intensively for backups, I access them once a year.

I see. Is this your new obsession? First the refurbished drives, now this?

It's not an obsession, it's learning about 2.5" HDDs and the serious problems of demagnetization and bit rot.

If you say so ..

Yes. Affirmative.

Some people say that humidity and high temperature (34-36C, 57-67%) causes demagnetization and bit rot in 2.5" HDDs, other people say that it does not and that only strong magnets cause these problems, what is the truth?

They're probably right. Do they also tell the speed of these processes, before they become a problem? Days? Weeks? Years?

What problem are you trying to solve / answer? If it's okay to buy old (refurbished) hard drives and rely on them?

Will long-term storage of 2.5" HDD at 34-36C and 58-68% humidity cause demagnetization of the platters? demagnetize corrupt files

Try restart your chat bot, this makes no sense.

You still haven't answered the question about storage temperature and demagnetization of 2.5" laptop HDDs

This is what AI is bringing us, people.

Your initial question makes zero sense.



For example, you ask, "does storage temperature cause long term demagnetization and bit rot". While storage temperature may be a factor in hard drive degradation, your question is nonsensical. And all you do is ask nonsensical questions. Of course you don't get serious answers.

What would be a meaningful question? I tried to be as serious as possible but you don't like to share knowledge

2.5" laptop HDDs are magnetic items, the loss of magnetism in the platters is something serious that compromises the files, I don't have technical knowledge of what the magnetism of these HDDs is like but my storage conditions are bad I don't have temperature control it varies between 34-36C and I would like to find out if this temperature slowly causes the loss of magnetism in 2.5" laptop HDDs, the humidity is also not perfect it varies between 58-68% does it also cause demagnetization?

Okay, even if you'd rephrase the question into something coherent, then you ask too much, too specific. Say humidity affects metal parts, temperature affects magnetitic properties to a degree, age affects lubrication properties, let's assume all this, then by no means this would be accurate enough to predict failure of shelved hard drives, and whether or not data on them would be intact in 5, 10 or 20 years. And to test these things, you'd actually need to have to an enough large population of drives you test under varying sets of parameters. And by the time you complete the tests the results might very well be irrelevant due to new technology and such, higher densities, different materials etc..

i some reffer demagnetization and high temperature 36C
