an actual photo of a hard disk label where it is printed in large, friendly letters:
Caution, product warranty is void if any seal or label is removed, or if the drive experiences shock in excess of 300 Gs
I got curious in what 300 Gs (which should actually read as g -you normally don't put the plural on symbols of units of measurement ) do represent in layman's terms.
There are quite a number of posts in forums around where mostly inexperienced people threw in hearsay, absurd calculations, semi-random numbers and what not.
A quick check on Wikipedia clears some aspects:
whilst documents from the actual manufacturers, like these:
once stripped off the fluff, say next to nothng useful.
Anyway I seem no to be able to find ANYTHING giving an adequate answer to this question:
Can you provide a common practical example of a situation where a hard disk will experience a shock of roughly 300 g's?
(backed up by some calculation OR test data)
This document is finally clearing something:
though knowing that
The acceleration experienced by a laptop if it is dropped from a height of three feet onto a
can hardly be called "narrowing" the problem.
Would anyone REALLY (which means NOT "from what I remember from physics at high school, if you divide space by mass and multiply by PI you get ....." kind of thing) understanding the matter provide some calculations/examples?
