When I power off the system (with poweroff) the connected USB HDD makes a noise that comes from the heads. A distinct clicking noise.
This sounds like the head-assembly being retracted.
I wanted to know if there is a way, when powering off the system, any usb hdd drive that is connected to the system be stopped properly, and the disk heads are parked?
To power-off my external USB HDD on FreeBSD I do: $ sudo devctl disable umass0 $ sudo usbconfig ugen0.3 power_off (umass0 and ugen0.3 may differ) On NetBSD I do: $ sudo drvctl -S umass0 $ sudo drvctl -d umass0 before unplugging the drive. (not exactly equivalent as there's no power-off.) -RVP
