SSDs and flash memory need to be refreshed (rewriting all the same files) at intervals of 1 year or more to keep the data intact and free from corruption and bitrot.
Do 2.5" and 3.5" HDDs also have this problem? Even if the drive is in good health, if the data was written many years ago, are they at risk of corruption, loss of magnetism, bitrot, and other problems?
generally i acess energize my drives 1 once year more no nothiting write
Do 2.5" HDDs for long-term storage require specific, perfect conditions of 50% humidity and 25°C? Is oxidation and corrosion possible above that?

The WD10JPVX is an old 1TB hard disk which is probably close to the end of the road. Not sure about the HTS541010A99E662. Can you post screenshots from Crystal Disk Reports.
USB sticks at 1TB are available and are not that expensive.
HDDs do not need periodic rewriting like SSDs. Magnetic data does not fade on a healthy drive just because time passes. Bit rot on HDDs is rare and usually tied to failing sectors not age alone.
Powering the drive once a year is fine but it does not refresh data. What it really does is keep the motor and bearings from seizing and lets you catch failures early. Loss of magnetism is not a real concern for modern HDDs stored indoors. You would need extreme heat strong magnets or physical damage.
Temperature swings are a bigger risk than steady warmth. Your 33–38°C range is warm but not dangerous for stored HDDs if airflow is decent and the drive is powered off most of the time.
55–66% humidity is higher than ideal but not catastrophic. Corrosion happens over many years and mostly affects connectors not the platters which are sealed.
2.5" and 3.5" HDDs behave the same for long term storage. Laptop drives are not more fragile when sitting unused.
my hdds 2.5" models: WD10JPVX‑08JC3T5 and HGST HTS541010A99E662, ST500LM030
Are the arms and heads of the 2.5" HDDs sensitive to external electromagnetic fields at close range? Example: big crt TV 29" turn on 2cm distance for HDD 2.5" will the sensitivity cause wrong random movements and lack of control of the heads and arms of the 2.5" HDD?
So, a 2.5" HDD at a distance of 2cm from a large TV turn-on, and any magnetic degradation weakening in the HDD, exposure for a few minutes versus several hours or even 48 hours, is the result the same? Does the magnetic degradation in this case depend more on the strength of the external magnetic field or the exposure time?
Can 2.5" HDDs be used for long-term archiving data, or do only 3.5" models have different and more resistant platters and mechanical?
Regarding the mechanics and lubricant, do the platters of 2.5" HDDs degrade faster with several hours of use every day, or with use powered on once a year for a few minutes? They are both in the same environment with the same humidity and temperature.
HDD 2.5" stored in 31-38C generates slow demagnetization platters?
2.5" HDDs lose magnetic strength and degradation of the dishes near 2cm of big crt tv 29" turn on a distance 2cm hdd and tv?
No, a big CRT turning on 2 cm away will not mess with the heads or demagnetize a 2.5" HDD, especially if the drive is powered off with heads parked. The magnetic pulse is brief and drops off fast, so exposure time doesn’t really matter here. What actually hurts 2.5" drives long term is heat, shock, and sitting unpowered for years, not nearby TVs. For archiving, 2.5" HDDs are fine if kept cool and spun up once or twice a year.

HDD 2.5" stored in 31-38C generates slow demagnetization platters?
2.5" HDDs lose magnetic strength and degradation of the dishes near 2cm of big crt tv 29" turn on a distance 2cm hdd and tv?
No a 2.5 inch HDD sitting 2 cm from a big CRT TV will not lose data or have its heads go wild. Hard drives are sealed and shielded and the heads are positioned by a closed loop system that ignores outside noise. The magnetic field from a CRT drops off fast with distance and is nowhere near strong enough to demagnetize platters even over days.
Time does not really matter here because the field strength is too weak to begin with. Heat and vibration are far bigger risks than magnetism. Using a 2.5 inch HDD for long term archive is fine and the platters are not weaker than 3.5 inch ones just smaller.
Occasional power on is healthier than running them for hours every day and your 31 to 38C storage temps will not slowly erase data. Bottom line a nearby CRT will not cause head movement damage magnetic loss or corruption in these drives.
I have used LCD for so long that CRT issues are long gone. An old CRT television lacks the picture quality and clarity that even low cost LCD televisions can offer.
SATA SSD costs are low and for media containers even USB sticks can handle a lot of content.
Please explain to me how the shielding and sealing of these 2.5" HDDs works, especially my older models that I mentioned before.
And if the magnetic fields from the large 29" CRT TV turn on at a distance from the 2.5" HDD turn on, will the magnetic fields destabilize the movements of the arms and heads, potentially scratching the platters, and will these magnetic fields from the CRT TV weaken the magnetism of the platters and data?
What maximum temperature this modelos support in storage mode without demagnetize? My varies 31-38C
Your environment is fine. HDDs do not need perfect 25C and 50 percent humidity to keep data safe. 33–38C and 55–66 percent humidity will not cause magnetism loss or corrosion unless moisture actually condenses which usually only happens with rapid temp changes. HDD data is very stable sitting powered off for years and powering it on once a year is enough. Just avoid heat trapped spaces and keep it dry with silica gel if possible.
