From the eeePC user guide:
Transportation precautions:

The solid state disk drive's head retracts when the
power is turned OFF to prevent scratching of the solid state disk
drive surface during transport.
Therefore, you should not transport the eeeP when the power is still ON.

FLASH read head?
LOL.


Is this really true even for the usual hard drives?

I routinely (carefully) transport my laptop while it's on. Bad idea?

I've had a laptop with an accelerometer - it parks the heads when it
senses acceleration.

Lack of acceleration, I should think. It would normally measure 1g
(upward), but in free fall that would be just about exactly cancelled
by the accleration of the laptop (downward) toward the floor.

Maybe - it actually measured the direction as well as magnitude,
IIRC. You could pick it up and turn it about, and I think there was a
little picture of the laptop that followed the orientation. Can't
remember exactly now, it came with vista which only lasted a couple of
hours before I stuck linux on it.

Sure, probably a 3-axis acclerometer.

It may have done both- if the laptop was being jostled OR in free
fall, then park the heads for a bit until the turbulence or
weightlessness goes away for a while.

Just wait until they start making a $5 6-degree-of-freedom
IMU-on-a-chip.
