Is it safe to place the HDD inclined?

[l_r_c_t]

alright, the question is as written above.
what i mean is that the HDD is not placed with his four "legs" on the table his a bit inclined, and I wonder if it can disturb the HDD work. (just to be clear I'm talking about an exteriour disk).
Thank You all.

yes they will work at all different orientations.

the main thing is not to move it when it's running.
