How to stop any file indexing?

I see .wdmc folder, every time i delete it, it appears again with thumbnails of all my files.
I use drive only as SMB-drive, and i do not need any additional “services” that freezing my device.

Plex and twonky are down, but no any changes.

Maybe you are not supposed to delete it, and if you do the system rebuilds it. It is a hidden folder containing a databse for the MPW. I have same folder on my device. It is dated 2015, so it has been on drive a long time. My MPW works flawlessly and it too is used for sharing the media files via the My Cloud app and other SMB apps.

Still no solution? It is making disturbing noise, decreasing drive lifespan, wasting battery, producing excess heat, slowing performance, why was it ever a good idea to force the drive read/write continuosly?

Maybe ssh command lines?

cd /etc/init.d/

chmod a-x S85wdmcserverd

chmod a-x S92wdnotifierd

chmod a-x S55netatalk
