Another explanation could be: heavy trucks stopping outside near a traffic
light, the whole room vibrates, even my ears vibrate a bit, I can also feel
the secured/fastened harddisks vibrate a little bit.
I wonder what that vibration effect would have on unsecured/unfastened
harddisks.
It's a rare kind of event though, many trucks go by, but only some of them,
perhaps maybe even a single one has just the right frequency and perhaps a
heavy motor or weight that creates big vibrations on the building in which I
and my PC are at.
Perhaps this could cause some short lived super vibration/resoning. It's
somewhat far-fetched but otherwise I cannot imagine my gentle actions to
have caused any damage.
Yes I did move the harddisks a little bit while they were on but only to
remove the dust filters.
Your claim that harddisks rarely recover goes directly into what I am
seeing, my harddisks are still working and recovering, so this seems to
confirm your mentioned "rare events".
This is not a typical harddisk damage scenerio that I am facing it was
something special/rare I think...
(Though I could be wrong I can remember one instance where I came home and
bumped the table and I was like: "oh shit I shouldn't have done that"... but
I already tried that kind of bumping I think and didn't do any further
damage... hmm bit strange... maybe PC wasn't even on or maybe it was...
vague...)
Hopefully it/the rare events/possible vibration hypo won't happen again now
that all 24 screws are in !
Thanks for the reply it was interesting to read and also seems to explain
the ticking noise I heard !
