I sure hope not.

All I'm saying is that the "shock protection" effect seems to be largely
imaginary.  Power saving is good, sure, but I really hope this whole
hard drive-destroying problem wasn't created in a misguided attempt to
protect drives when they are dropped.  Dropping a laptop is not exactly
normal use, and the chances that this would actually protect your drive
seem pretty slim.

If you drop it on AC, it's going to break.  If you drop it on batteries
while the head happens to not be parked, it's going to break.  No matter
what hdparm is set to, if you drop it hard enough, it's going to break.
