Hello, Arno:
Sorry, disagree. My SimpleTech "SimpleDrive" external hard drive (160GB,
USB 2.0, 7,200 RPM, 3.5") contains a power switch, on its enclosure.
Hence, I only leave the disk running, fairly briefy (i.e., long enough
to back up new files, daily).
My old Micro Solutions "Backpack" external HDD (30GB, USB 1.1/parallel
port, 5,400 RPM, 3.5") was a different story, however. It had no
such switch, and its rotational speed was somewhat slower.
Besides, unlike the SimpleDrive, the Backpack would automatically spin
down, if it wasn't accessed within a relatively short period of time.
(Neither device has ever caused any problems, either.)
Cordially,
John Turco <jtur DeleteThis @concentric.net> |

You disagree about my general statement, because specifically you
do something more sensible?

Well, a sample of two. That is not the way to evaluate reliability
of specific ways to operate some thing. No failure => Tells you
the failure rate is not astronomically high. Failure => Tells you
nothing.
Also I have evidence that not all enclosures do automatic spin-down,
since I happen to have 4 different models and not one of them does
spin-down. Of course these were all bought without drives, so there
may be some connection to that.

Well, there you have it. In a nutshell.

Wow, a sample of 4. So much better than a sample of 2.

There you go, babblebot: no drive to spin down. You nailed it.

Hello, Arno:
The point is, why does the SimpleDrive feature an on/off switch, in the
first place? I believe it's to keep it from overheating.

Just offering an opposing view, nothing more.

Well, I never claimed to have made a scientific study of the issue. <g>

Hello, Folkert:
I couldn't reply to Arno's post, directly, because it never appeared
on my news server. (Oddly, the same thing has happened with >all< of
Timothy Daniels' messages, lately.)

Ah, that would make sense. It also is an indicator that coooing
is inadequate then.

Ok.

True. I am just pointing that out. If you aready know that, fine.

That was not claimed or implied.

Wrong as allways. What I saitd was "there are drives that do not spin
down". A negative can never be demonstrated with a sample. A positive
can. But I guess thet is way beyond your mental capabilities....

Strange. Maybe complain to your news-operator, since I post
via News.Individual.NET, which is pretty large.

That's why my posts have attribution lines with the original message's
address in it so you can still download it.

Some news servers now filter sporger posts.

Hello, Arno:
I've been using Aioe.org (a free NNTP server), for about the past ten
months or so. My dial-up ISP (Concentric) had canceled its own news
server, shortly beforehand.

Because that is what Comstar says in the manual themselves. I think they
