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?

2.5" hdds need refresh rewrite data before 5 years similar flash memory and ssd?
 
  1. Will the magnetic fields or electromagnetic waves generated by a large CRT TV turned on at a distance of 2 or 3 cm from a 2.5" HDD turn on (older model manufactured in 2010 or 2011) disrupt, misalign and interfere with the correct movement of the mechanical arms and read/write heads, causing read/write errors on the 2.5" HDD?
  2. Do these electromagnetic waves and fields from the large CRT TV turned on at a distance of 2 cm from the 2.5" HDD (manufactured in 2010 or 2011) also cause magnetic degradation in the platters, corruption, and deletion of files from the platters?
