dropped hard drive onto concrete...what to check for?

[VirtualLarry]

I must say, given how little external physical damage the drive took from its drop onto the concrete these drive manufacturers are clearly waaaaay over-engineering the shell on the drives.

If I can drop it 3ft to concrete and the internals of the drive are dead then the outside of the drive can be equally destroyed for all that it matters.

Why design the shell to be capable of surviving plummets of doom (just adding production cost) that will render the internals destroyed anyways? Just sayin...

It's for mass dampening, for the platters.
