I use this for the data drive on my mythbox. I just put this in my
# Spin down in 1 hours idle time
hdparm -S 240 /dev/sda

Yep. What kind of safety are you worried about? It should just work,
although you want a long enough idle time that you're not constantly
spinning the disk up and down.
Is there any nice user-friendly frontend to set this? It'd be nice
to expose more power management choices to the users (for anything
that can't be easily defaulted, that is).
