Question Doubts about damage to my external HDD ?

Some people say that there are several models of the same brand and some stop spinning and others don't stop spinning when the HDD is ejected from Windows. Do manufacturers cut costs by reducing parts when manufacturing the 2.5" HDD?

That is a completely new question, and cannot be answered.

2.5" HDDs have been used in laptops for decades.
I have a couple, from before the turn of the century.

If they were as fragile as you seem to think, we would never have had laptops.

Why do some 2.5" HDDs not turn off after ejecting in Windows 10? Is this behavior common? Two people told me that they have several models of the same brand, some turn off, others do not, and this is a problem if when the hand hits the HDD case, the mechanical arm and the needle scratch the HDD. My HDD is very quiet. I only saw the LED turn on after ejecting in Windows 10. I have the models Seagate ST500LM030, WD WD10JPVX-08JC3T5, HGTS HTS541010A99E662
enclosure cases USB 3.0 Orico 25pw1 and Kesu 2530
If Windows 10 eject fails and does not power off the HDD, is there any other protection against hand shocks on the side of the case not damage or generates bad secxtors in hdd?
