Question about Ultrastar DC HC550 - 461567

Does the WD Ultrastar DC HC550 (18 TB, 3.5", CMR) also click every 5 seconds when it is booted up? It sounds like a drop of water dripping onto the bottom of an upturned plastic bucket. You can still hear the clacking at a distance of 6 metres. I have tried them in 2 external housings. If you touch the external case, you can even feel the clack. When writing data, the read head noise can also be heard, but it is within the normal range as with other disks and much quieter than the "clack every 5 seconds" that also occurs during data writing in addition to the read head noise. It works, but a mechanical noise whose vibration can still be felt on the external housing sounds like a defect to me. When it is not in use, the clacking stops at some point (presumably hibernation), but as soon as I start reading or writing again and it starts up again (with a very loud rattle of about 3 seconds), the clacking every 5 seconds is also back.
