I have a USB Hard Drive

In Windows, i used to click the "Safely remove" icon, and the hdd stopped spinning and was unmounted.

Now, in Linux, unmounting doesn't poweroff the device, and it proceeds spinning when i remove it's cable. Is there a way to poweroff the HDD?

Additionally, I'd like to teach the KDE's "Device notifier" plasmoid to do this :)

Try something like sudo sdparm --command=stop /dev/sd[x]

<b>sudo hdparm -Y /dev/sd[x]</b> also makes the device enter sleep mode. – kolypto Jul 27 '09 at 17:30
