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?
