Default Special laptop hard drive for aircraft use

There is no way to park a drive that has heads riding on the surface.
That's been the way nearly all disk drives work since the mid-1980s. I
believe the technology was invented by IBM in their San Jose disk facility.


Modern drives are voice-coil actuated and do not need to be "parked" or
"landed". When the power to the voice coil goes away, the head retracts
*completely off the disk surface* into small plastic storage grooves
just off the outer edge of the disk. There may be slight design
differences - but if you take the lid off a hard drive that's what
you'll see (obviously, don't take the lid off a hard drive you want to
keep using).
