I was looking at this question which is historic but massively upvoted, and I don't understand why it's off topic.
Mounting hard drives would seem to be very much on topic here,https://serverfault.com/help/on-topic
If your question is about:
managing the hardware or software of servers, workstations, storage or networks
I don't see any indication that anything about that question is prohibited or that the question is otherwise unclear.
Moreover, the question doesn't even seem basic to me: do drives having dampening mechanisms that require a specific orientation? Does drive orientation affect heat dissipation? etc. etc.
