WD HD Orientation

This is a dumb question but would really help me out if someone can answer it…The WD My Book External HD is designed to be standing up like a tower, i don’t like that for the obvious reson of someone knocking it over but the question is: can i use it horizontally and is there a particular side it should face? Thank you if anyone can help.

No, it is not recommended as it might damage the platters and affects the internal rotations in My Book.

No, it’s not recommended (laying flat) because of heat and ventilation issues.

WD Hard drives can be mounted in any position (x,y,z) without damage to platters.

Heat, is the only concern particularly in the case of external hard drives.
