Not entirely clear what you mean.

 

Are you mounting it with the Unassigned Devices plugin? Or do you have it in the array somehow?

There isn't a control in UD to spin down devices on demand. Doing it through USB is also a hit-and-miss.

However, most external HDD controllers will spin down on its own after a while without any user intervention. If yours isn't spinning down, it's likely that something is still accessing the drive.

But I used Synology's usb device sleep function before using unRaid and it is supported under the same conditions (installed a docker of jellyfin and set its media path with my usb device) even without use the hdparm command. I don't know which process accessing the drive when I'm not using the jellyfin docker.
