December 25, 20205 yr Simple question and the search didn't bring up a clear answer. I have a 4 TB WD USB disk which I use as a backup target. I already tried to spin down the disk by clicking on the dot next to the device, however, this seem to do nothing. Hence my ask for advise - can I spin down a usb disk? I don't want the disk to run 24/7, especially since they are not made for this purpose. And second question, can UnRaid eject disks like I can do on a Desktop OS? Or is pulling the cable the only way? Thanks!

December 26, 20205 yr 12 hours ago, doesntaffect said: I am using 6.9 RC2 I think it may also depend on the usb to sata controller. I know a Sony drive I have always report standby even when in use with hdparm. There is some useful info in the link below and may work for your requirements. https://unix.stackexchange.com/questions/35508/eject-usb-drives-eject-command
December 27, 20205 yr Author sys log has following entries: Dec 27 19:44:17 Ryzen emhttpd: spinning down /dev/sdb Dec 27 20:14:18 Ryzen emhttpd: spinning down /dev/sdb Dec 27 20:16:52 Ryzen emhttpd: spinning down /dev/sdb However, the green circle next to the device in the Main tab stays green, even after clicking on it. The grey turning arrows seem to be only a visual, without any effect in the background.
