EX2 Ultra waking up disc randomly

[locarno]

I noticed that after update to OS5 my EX2 Ultra wake up randomly when it’s not used. On OS4 it only waked up discs when used. No one acessing my cloud and I can hear disc starts spinning. Is that normal ? How I can check what causes my cloud to wake up hdd’s ?

Yes. There is other thread about it.

HDD waking up from sleep every hour

Since I updated my EX2 Ultra to MyCloud OS 5 both HDDs (WD Red 2TB) are spinning up every hour for no reason. No device on my network is trying to connect to the MyCloud, no entries for SAMBA in the Log at this times. I am not using Cloud Connection, no Apps are installed. Only using the MyCloud with SAMBA. HDDs are in JBOD. The log says * HD awake now! * or * HD standby now! * It is annoying that the HDDs are spinning up without accessing any files. [EX2]

Latest software should help but it doesnt.

So same issue on my side.
