Hi Douglas,
After our previous discussion on USB/Firewire start/stop, I asked on our 
dk LUG for info on external interfaces, but found none that seems to 
implement the needed SCSI functionality.
Too bad, would've been great being able to spin an external drive 
down/up as needed.

I think I read somewhere that one ATA disk (HItachi og Fujitsu) can do 
something similar automatically (i.e. adhering to a timeout), once 
configured to do so, using MS-based utils.
Dunno if those/similar are available for *nix.
