plastic ABS doubt shocks protection Hard disk

[jonas778]

ABS plastic case provides some kind of protection against accidental hand shocks and tabletop case for 2.5" HDD hard drives? I know that HDDs have a mechanical needle and arm, some types of knocks or shocks scratch the magnetic disk

Not really, but portable external HDs would probably benefit.
Any time I put HDs in external enclosures I usually slip some foam in there, because I tend to be rough with them.

I don't recall exactly, but an HD, with heads parked, should survive 50G.
If spinning, and heads travelling over the platters, even small bumps could cause the heads to crash.

In my case, I ejected the external HDD (2.5" HDD + plastic USB 3.0 enclosure case) in Windows 10, then I pulled the USB 3.0 cable from the PC, the cable came out and my hand hit the case with a shock and the case moved to the left of the table.

In the old days we used to click on  'disconnect USB device' to allow the HD to park the heads, before disconnecting.
I don't think I've done that in the last 20 years.

Is your drive not working ? Doesn't seem like you bumped it too hard.
If it makes weird noises when you plug it in, you may have crashed it.
If it sounds normal, but doesn't show up, try going into disk management to re-enable/re-partition/re-format.
Or you can, try opening it and checking any internal connections that may have come loose.

It's likely alright the read/ write heads have some protection to prevent the heads from damaging the disks
