Spin down disk if swap is used?

The title says it all... is it possible to spin down the HDD, if you have swap partition on it, and torrent_watchdog in cron, running every 30 mins?
Thanks

Not totally sure of this, but I presume spin-down would not be functional.

If you'd set the spin-down timeout short enough it will spin-down, but then probably spin-up rather quickly after that. Many spin-down/up cycles aren't good for your harddisk....
