Question HDD laptop

Do 2.5" laptop HDDs have a temperature range for long-term storage without risk of demagnetization of the platters causing data loss and corruption? Or does any temperature above 25C slowly cause the platters to demagnetize?

Yes... Cloudflare added problems to normal users of the forum, but did not get rid of abnormal ones. 
And for this, apparently, you need to pay... Sorry. Maybe I do not know the real reasons.

Especially WD10JPVX drives exhibit demagnetization. The more they approach the Curie temperature the more they are at risk to loosing data.

Does the Curie temperature work on 2.5" laptop HDDs or only on other magnetic materials that are not present in HDDs?

Eh, let's flood. I have never come across any information from HDD manufacturers about the magnetic material of the plates.
Trade secret. You can ask the manufacturers about the Curie point of their material yourself.
The loss of information is most affected by the tendency of magnetic charges to average over the surface. Google to the rescue.
If you are not going to heat the HDD above 150 degrees...

In the datasheet of 2.5" HDDs there is a specification for temperature operation and temperature non operation, does this have any relation to problems related to demagnetization if the temperature is outside the range?

No, it doesn't.

SWM,
in cause you may not have noticed:
The famous SonicMario who left his traces in all computer forums of the world under a variety of names that even CIA, KGB and Mossad together could not create together, is articulating his "doubts".
Today it is demagnetization, tomorrow it will be sun bursts and EMPs.

What is the Curie temperature of 2.5" HDDs? Is it much lower than the operating and non-operating temperatures shown in the datasheet?
When the Curie temperature is reached, does demagnetization begin?

rec,
It was interesting to assess the level of this AI. But it is only very interested in questions of self-preservation. Which are not available on the Internet. So it has already realized.
