So I have 5 SAS Drive in my system currently, 4 of them that's in a array seems to spin down without any issue, but my issue is that I've leave a single drive which I was planning to use as backups that won't spin down. since I won't be around server for almost a year, is there a proper way to have drives in the server that's deactivated until required?

 

Also I did try to click the Spun down on the unassigned drive which sadly doesn't seems work.

Tho for some reason it seems to works fine for both sdd and sdf? (Their both in a Array unlike sde which is currently unassigned).

teh spin down function is esental the disk in idle / sleep a unasgned disk that is not in a pool or array will not triger a spin down as it is already in a idel state untill soemthign is read/wrting to it. It however being a unasgned disk will not gain and performace/power boost and there sin't much there when it is a unasgned disk.

ths can be done via web ui

That's the weird thing tho, UnRAID seems to have no issue spin down drive in a Array, but for some reason when clicking the green dot in the GUI for the unassigned disk, it shows that it's trying to spin down the drive in the log, but green still remains green after wards.

 

And 2 of the drives that's in the array is the exact same model, so there shouldn't be any issue with drives as well.

SAS spin down is not supported by stock Unraid, you can try the plugin.
