Change mounting orientation after long usage

Hello Peter,

thanks for your answer!
And this is also the case when the drives has already has been ran many hours
in another orientation?
So the “well attuned” mechanics or “ingrained” bearings does not really exist
and somebody told me a urban myth?

Speaking of myth… you wrote “any X, Y, Z orientation”.
I once heard drives should not be mounted at a sloping angle.
For example at 45 degrees. Only 0/90/180/270 degrees.
Also not true?

Thank you!
Greetings,

Martin
