MOST interesting comment from someone with a 13-year old's
nickname (if it's your /real name/, my deepest sympathies) who
(to my recollection) has never posted ANY advice, and who uses
OE for newsgroups.

I am often wrong, and have no problem with admitting it when I
am corrected by someone who knows what they're talking about.

But NO ONE is ALWAYS wrong or ALWAYS right - including you.

Now go **** yourself.

What struck me about their study, is the word "humidity"
doesn't appear anywhere in the report. And humidity is a
factor in disk reliability.

Not heard that touted before.

You sure you're not just confused about the air conditioning issue ?
Reasoning that since big installations are kept in a/c'd rooms (dry
atmosphere), non-a/c'd (relatively humid atmosphere) installations must be
less reliable ?

Big installations aren't air-conditioned because of humidity.
They're a/c'd because that's the only way TO cool a room.
Humidity is purely incidental.

That's some pretty weird-ass reasoning you've got.

I judge studies by their attention to detail.

Without knowing what combination of temperature and humidity
is present in each facility, there is no way to judge whether
the missing factor is important or not.

If you download an OEM spec for a disk drive, there is
a temperature/humidity graph in it. It documents the allowed
values of temperature and humidity for a disk drive. Which
means in any study, humidity should be documented (because the
disk manufacturer acknowledges it is a factor). Or at least the
word should appear in the study at least once, as in
"we chose to ignore humidity".

Yes, but that's for un-a/c'd conditions (under which, the majority will be
used).
In a/c'd conditions, it become irrelevant because the temp is kept low
enough that humidity is of no consequence to the cooling capacity of air.

Okay, extricated from the case and hooked it up with SATA cables, it's
working fine. Apparently the My Book interface/switch died.

Thanks for all input.

I sort of hate to say this, but didn't that sort of imply my
rather simple rule has again proved to be correct?

Now try to sell the external HD case for the $10 it /may/ be
worth and you'll be done.

Rod Speed is the last great polymath. The most that you and I and the
rest of us mere mortals can hope for is to learn a little about a lot,
or a lot about a little.

You are probably encountering him for the first time as an undesirable
consequence of the OP's crossposting. When you crosspost to
comp.sys.ibm.pc.hardware.storage you run the risk of introducing Rod
Speed to an unsuspecting audience. It's a bit like bringing your
neighbour's dog poop to your friend's house on the sole of your shoe.

Most of the regulars have kill-filed the troll, but he still tries to
get through by nym shifting. Pathetic, really.

During the 1980s I was involved with one minicomputer installation
that had problems with a particular Control Data BK7 series disc
drive. After experiencing lots of static related issues (status
errors), the customer installed a humidifier to increase the humidity
to an acceptable level.

In other climates, such as Singapore, the high humidity promotes mould
growth on magnetic media, although I doubt that mould would get a
foothold on disc platters rotating at 7200 RPM. :-)

I found this interesting Samsung patent whose inventors claim that
"flying height drops significantly in humid conditions" and that this
can be remedied "by increasing the temperature of the air flowing
between a slider's air bearing surface and the rotating disk surface
it accesses".

Even if humidity is assumed to be a low, constant in their
study, things held as constants should have been mentioned.

Agreed.
But that has no bearing on the issue of humidity under a/c.
Similarly, there should have been mention of power supply
failures and electrical surges, as these also pose risk to
powered parts.
Click to expand...

Indeed.

There should also have been mention made of
chassis /cooling design if all systems were not identical,
not just temperature of the drive which can vary per make
and model of drive and is not indicative of multiple
regions on a drive like the logic IC or motor controller.

As I said, it was hardly a scientific study.

Well, if the FAQ is correct, at least the poor thing has
something to amuse himself with. There is so much trolling
spamming and crap on the Usenet it makes little difference in
the final analysis, I think.
