Definitely true. But do not expect a head crash, if power is removed!
Since many, many years *every* harddisk does auto-parking. This means that
it uses a mechanical spring or the energy of its rotating platters to move
the head in a safe position in case of a power failure.
(see more,for example here: http://www.pcguide.com/ref/hdd/op/actParking-c.html)

Nevertheless I prefer a clean shut-down, because software (especially FAT32!)
does not know anything like "auto-parking". So what might be a problem is a
power-off while writing/deleting/renaming.

Greetings...
