If one does a search they’ll find numerous threads where this is discussed. Here is one such thread:
The thread above goes into much more detail including how to stop the scanning at device bootup, but basically one uses SSH to access the My Cloud and issue the following commands to stop the two services that do the scanning until one restarts/reboots the My Cloud.
/etc/init.d/wdmcserverd stop
/etc/init.d/wdphotodbmergerd stop
Also see the following thread which has much more info on the media server within the My Cloud.

If you don’t plan on using the media server feature of the My Cloud then access the My Cloud Dashboard and disable Media Streaming and iTunes Server. Both settings are found on the Dashboard > Settings > Network page.
