mdgm: Your q about services made me do some tests.

I found that the problem probably is caused by the ReadyDLNA-service.
By disable the entire ReadyDLNA-service or only it's autoscan functionality I got the
spin-down working with inactivity settings 30 minutes and higher.
Can anyone else confirm this? Is this normal behaviour?

If it is scanning very regularly for new files, yes it will prevent the disks from spinning down.

Disk spin-down is useful for units with low numbers of services running with long periods in the day when data is not being read.

I had some initial problem setting up the disk spin-down functionality.
Is it so that you have to set the start time for spin-down well within the interval for power schedule?

Power 11am - 1am(next day).
1. Spin-down 12am - 12am working
2. Spin-down 10am - 12am and 11am - 12am not working

Running OS 6.2.4 and been seeing this on early 6.2.x.
