One of the nice features of recent Fedoras is that the power managers allows you to spin-down disks when unused. This has been a real power/heat/noise savings.
However sometime in the past few weeks this feature has ceased to work as expected. I have a backup drive (/dev/sdc) this is only used for one period at night, and the normally when I do an "ls -l /backup' (the mountpoint) in the day the drive has to spinup for 3-5 seconds before I get a result. No longer the case - it's always spinning.
In XFCE power manager, under the "On AC" tab, I have the "Spin down hard disks" checked.
In the past that was all it took.
Sadly as with the corresponding Gnome power manager there is no way to debug or monitor this that I am aware of.
Anyone else seeing this ?
Time for bugzilla ?
