There’s a system log that’ll tell you some stuff about what wdmcserver is doing. It’s at
/var/log/wdmcserver.log
Mine only starts when the file system is changed (right now it’s doing it every hour because Windows 8 is doing file history backups to the EX4, but prior to me starting that up a few days ago, it went WEEKS without ever doing anything.
My CPU right now is at 8%, and wdmcserver and wdphotodbmerger processes are both 0%.
