I have an old type VR X (150GB). I like to remember that the manual stated NOT to mount it vertically. The manual for the latest Raptors only mentions horizontal mounting in the examples, but does not specifically mention not to mount it vertically - I just want to reconfirm I can mount the new models ‘any way I want to’ before it throws discs at me at 10K RPM 
Many thanks!
I don’t think is such a big deal with the new drives, however is better if you get the official response from WD. You can reach them by email or by phone.
