[RC5] MacOS X - Hard disk sleep

Why not let it spin 24/7?

True, you save power by sleeping the harddisk, but from my experience,
the drives and the unit burn more power and experience more wear by
spinning up from sleep mode.   Really nasty if your drive goes to sleep
after 5mins and you return from coffee pot or phone conversation.

I burned through 5 SyJet cartridges using "sleep mode" on SyJet.
I wasted another 3 hard drives before learning to turn off the sleep mode.

Sleep the drives only when there is NO system activity.  This lesson
also comes from working as operator of Wang/DEC cartridge
disk computer units.
