Hello JohnO,
Thanks for your added input expanding on my opinion.
My (other) opinion is with respect to gasoline/diesel engines is that the
worst thing you can do to them is start them up.
Engines are most happy when their running at a constant nominal RPM, at
normal running temperatures and under a light load.
Starting them on a cold morning (like you mentioned), causes all kinds of
thing to expand due to temperature rise. When the engine cools back down at
shut-off, things loosen up like seals and gaskets and bolts just to mention
a few. And of course all the oil drains back down to the oil pan. But then
the automotive industry does a heck of a good job when it comes to dealing
with this sort of stuff!
My PC has (4) internal hard drives, (2) of which are seldom used. However
(all) drives spin up at boot. So the 2 seldom used drives simply spin down
after 45 minutes. It's a shame that "Power Options" won't allow different
time settings for individual drives. I guess this is another argument in
favor of the USB external Hard Drive. It will only run when you turn on the
power to the enclosure. But then the disadvantage is that if it's powered
up... it's spinning all the time. It doesn't adhere to the "Power Options"
settings and it will sit there running even if the PC is turned off. At
least this is the case with mine. I leave it off unless I need it for
something... like to run a backup every month or so.
The Windows OS default configuration out of the box is set to run the drives
all the time. I've always had to change my settings.
Anyway... to get back to the question from the OP. I agree that the Tech
support people at any of the drives manufacturer's are better prepared to
answer that question. I've called Seagate Tech Support several times and
they are quite helpful.
Now I suppose that my input has pretty much put h4nne5 right back where he
started... sorry.
regards,
Richard In Va.

ok, this might sound a bit bitchy:
isnt there someone who has something usefull to comment? :-)
and thanks for the search tip, thats exactly why i posted! if you go
trough the result you can see everyone tells something different!
That's because the only people who can really answer your question are the
folks at Toshiba, Hitachi, Seagate, etc. They run the long-term life tests
under varying conditions, collecting real actual data and seeing real
actual failures. Everything else is guessing.
As for a guess, I used to do life testing for TVs and cable boxes. Heat is
an enemy, as Richard noted. Overheating is really bad, too. But what
magnifies that problem is constantly changing heat, which makes components
expand and contract regularly. That makes TVs and cable boxes fail, I can
tell you with certainty. Based on my experience, I turn the device on and
leave it on as long as I can, assuming it receives proper airflow or
heatsinks for cooling. Or if I want to save power, I let the drives stop
spinning.
Yet another internet opinion. :-)
