My guess (really a SWAG) is that it's bettter to leave things just happily spinning, 24*7. In Nov, '99 a power off//on destryed my new (105-day-old) 9G SCSI drive. Off ffor fewer than five seconds, then a spike or two, and the drive went deadder than a decade-old corpse. Lost 10 months of files. ((Well, my tape backup had flubbed up.)) Who would know??? I've heard both sides, and so far, just leaving drive spin seems slightly better. {Futureistic[?] idea: maybe a new drive can have a mode of Full-Operation and (slower) Spin. It wouldn't take more than a second to transition from the slow-spin to full-op mode. Open files, OS states, and whatever could be stored to RAM... .
