Question Power management of eSATA/USB/Docking station via CLI


Hallo,
I want to do something similar to the unanswered question of this post:
http://www.linuxquestions.org/questi...d-cope-424089/
Meaning:
I want to have an external eSATA or USB(3 preferably) or docking station to host a large HDD on which I will save my backups.I really need to control the power on/off of the external HDD via the CLI. How can I do that?

Thank you
Peter.

udevd might control the loading of drivers , mainly by triggering the modprobe command or a shellscript using the modprobe command , after some files for the new device show up somewhere in /sys .

I don't know if it possible to poweroff an external /dev but the hdparm command could be cabable of spinning down a drive .
Aditionally there is also a sdparm command .
