Do 2.5" HDDs have any protection against impact or accidental shock hdd 2.5" in power on operates to prevent the needle and mechanical arm from touching the magnetic disks?

Do 2.5" HDDs manufactured in 2012/2013 have this protection or only the most recent ones?

Does shock to the 2.5" HDD case when moving it on the table make a big difference to the HDD falling from the table to the floor?

Make and model HDDs?

Are you referencing "head parking"?

Shock is a matter of G-forces" acceleration/de-acceleration.

Strength and direction matters with respect to the internal components.

Overall if an HDD was "kicked" hard enough across the table the end result would likely be the same as if the HDD dropped from the table.

A car hitting a telephone pole at 60 mph would likely have the same shock as if the car nose rolled off of some parking garage level and hit the ground at 60 mph.

There are variable: a car hitting a telephone pole head on at 60 mph may crumple. If the car hits the telephone pole while sliding sideways at 60 mph then the car may be cut in half.....


As a starting point:

Generally the "real world" damage or consequences of dropped or hit HDD's are due to losing data on the drive.

Hence the need for having multiple, proven recoverable backups.

Just my thoughts on the matter.
