disk spin down.

[Peter S Galbraith]

I apologize if this isn't the proper forum.  I don't know if this
is handled by the SCSI driver or not.  I use Linux pre-patch-2.0.31-3.

I have a spare disk I use exclusively for nightly backups, and 
optionally seldom used swap.  I'd like to spin down the disk when not 
in use (and unmounted) because of it's whinning sound.  

Can this be done?  
Thanks for any answers, advice, or pointers as to where to look for
answers.

Peter
