The point is, however, that modern disks have enough time, on a
powerfail, to retract the heads before the cushion fails.

Modern disks don't retract the heads like the old ones did. The old
ones
had ramps which the head carriers went up when the heads retracted,
this
removed them from the surface. Modern ones land on the disk surface,
they retract to a "safe" landing zone.

Of course, dennis. Just like the latest WD Caviar Black, which uses
ramp
load.

That's one of the latest ones with shock protection isn't it?
Not all have that.

and yet a sentence earlier, you claimed that "Modern disks don't
retract the heads"... Does this not cause you cognitive dissonance?

No, why would it.

Because the two are contradictory.

Anyway its easy to wriggle out of as you would have to prove no modern
disks land their heads to show what I said was actually untrue.

No, your logic is flawed...

Take it a step at a time, its quit easy. You said:

Modern disks don't retract the heads like the old ones did.

Yes, and if any modern disk doesn't then that logic is true.

You don't understand logic is what the evidence suggests.
