Just out of curiosity, is it possible to power down an unmounted disk on

One I keep in my desktop for "backing up" the home fileserver critical
files is 'orribly noisy and if I could get it to shut up until I want to
mount it again...

You can even do that while it's mounted, on a shared ide channel!

The command is hdparm (as root of course).
You'll want 'hdparm -y /dev/hda' to put it in standby mode
or 'hdparm -Y /dev/hda' to put it to sleep.
They should (from my experience) come back online when they're wanted.
