Question HDDs + case usb

[nogueiraat]

I use a USB3.0 enclosure case, brand and model Kesu 2530 and Orico 25PW1 black, i use 2.5" HDDs models and brands Seagate ST500LM030 and WDC WD10JPVX-08JC3T5, APPLE HDD HTS541010A99E662
In Windows 10 and others Windows there is an eject function (safely remove hardware) when this function is executed and the HDD + case does not appear in Windows, for example "E:" even with the USB3.0 cable connected to the PC on/case. After all this happened, my hand hit the USB3.0 enclosure case and it moved on the table. Did this hit cause friction between the 2.5" HDD read/write heads and the magnetic platters, scratching them?

One would expect the heads to be parked (off the platters) if not actively in use.

If it still works then it must be okay?

but I thought the parking only happened when disconnecting the USB cables and cutting the power

after eject windows disappear letter E:

Your HDD is just slowly dying and you won't revert it from doing it

1) When the Windows "safely remove hardware" eject is invoked and the letter E: disappears from Windows, what type of command does Windows send to the 2.5" HDD and the HDD understands that it is time to park the heads?

2) Do the model, brand, chip of the USB3.0 enclosure case and Windows power settings have any relation to the parking of the heads of a 2.5" HDD after the Windows "safely remove hardware" eject command is completed and the letter E: disappears from the system?

3) In what year on 2.5" HDDs and in what version of Windows was parking the heads of 2.5" HDDs implemented after the Windows "safely remove hardware" eject command is completed and the letter E: disappears? even if the USB3.0 cable of the enclosure case remains connected to the PC/enclosure?
