Most survivability standards I have seen talk about G's as in Gravity's.
The same type of shock you would sustain when going from a moving
state to one of no motion (I cannot remember the scientific terms)
You know how many G's force does your body absorb when you car goes
from 60 MPH to 0 MPH when you hit a brick wall?
A falling drive does not really sustain damage if it is in an off
state. Heads parked, no movement. But if the drive is spinning and
the drive goes from one of motion to one of no motion can it
survive? If so what is the G force needed to cause it to stop working?
That to me would make more sense.
(I have seen some where they talk about dropping it so many feet
before it caves.)

I suppose a lot depends on what "G" is. 1000 grams is only 2 pounds.
But this seems to be talking about electrical standards, and maybe
it's too early for me, but I can't imagine what a G might be. Without
a link to the source of the data it would be hard to dispute the guy.

1/2 sine pulse, and 2.5" laptop drives ~1000G, when not operating.
Server-grade drives have lower ratings.

steel billet survives a 1000g impact.
