Hello
Tested with different disks and with all versions between 14.0 and 15.2 : the bug is attested. The spin-down function was OK in 13.6.
Do you know why this bug hasn't been solved within more than 19 lonnnnnnnnnnng month ????!!!
Yet it has been reported long time ago !
New RST 14.0.0.1143 doesn't allow HDDs to spin down (bug?)
Thank you
