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?

Every drive has a different temperature, and there is always a risk regarding data storage.

My HDDs 2.5 models ST500LM030, WD10JPVX-08JC3T5 and HGST HTS541010A99E662

. Regarding HGST, I can't find any information on temperatures. But I, for example, have 4 WD Purple 10 TB drives on the site and under load 35 degrees, but on the other hand the WD Gold 10 TB has 45/50 degrees under load. The fact that these drives you have are already quite old, show smart of these drives with CDI.

What temperatures? For My models not Demagnetize?
