Hello, I can't make hdparm works on my NSA which runs Debian Stretch on kirkwood u-boot and kernel, so i shift to hd-idle. If anyone is interested, this is hd-idle 1.05 compiled for Debian Strech armel architecture: https://sourceforge.net/projects/davidegironi/files/deb-packages/hd-idle_1.05_armel.deb/download Full instructions of my experience on running openmediavault on the NSA310by davide.gironi - Debian
