Just wonder if it's better for an HDD not to spindown at all.
Maybe it's safer to spin in peace than to park/launch?
What do you think?
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... .
Any little old winemakers, er, diskmakers out there?

Good point. The worst stress points during a disks life are at spin-up
from what I've read.
Also, about the disk spinning at different speeds: many contemporary
disks have "acoustics" levels where you can adjust the speed on demand
(assuming you knew the hardware level instructions to send to the
controllers). Unfortunately I don't know those settings, so I can't say
what is and isn't possible.
The only upside is at least all disk makers seem to be amalgamating into
either: Fujitsu, Hitachi, Quantum, Seagate, and WD, so figuring out the
standards shouldn't be *too* hard =).

Hello again all,
I was wondering if there was an automatic, and possibly timed means to
spin down disks available in either ports or the base system, by chance.
Just trying to cut down on energy use, and increase my disks' lives :).
TIA,
-Garrett
