there is additional photo scanning / thumbnails beside twonky. this is used to the WD photos & WD my cloud apps. If you don’t use either of these and are even a little bit comfortable using SSH in Linux you may want to disable these
to put them back later just change stop to start & disable to enable
these stop the current processes
/etc/init.d/wdmcserverd stop
/etc/init.d/wdphotodbmergerd stop
these prevent them from restarting at boot
update-rc.d wdphotodbmergerd disable
update-rc.d wdmcserverd disable
