I'm building my marvelous Myth box at the moment and I've been thinking about keeping the discs spun down when the box isn't in use.

After a bit of searching around various man pages I came across the page for hdparm (written by some joker called Mark Lord ) which specifies a spin down period. But I've read on the net that it might not be enough what with logfiles and cron tasks and the like. Anyone care to shed some light on this, or do I have make do with constantly spinning discs?
