Folklore for PC's was that if you recorded data on
a hard drive with the
platters horizontal, remounting it vertically could cause read errors. Any
truth to this?
It might be true for the old hard drives that used stepper motor
positioners, or some other system where the positioning was 'absolute'
rather than taking a position reference (servo) signal off the platters.
With those drives, the force of gravity on the head assembly might move
it slightly off-track.
Servo-tracked drives position the head by reading signals off the
platters, and will correct automatically for gravity, etc.
