Do you also disable the drive's own internal cache?

You're right, I can't. I also cannot provide information about electronic
components damaged by a UPS.

Probably will not even try. Power failure does not cause
hardware damage - except where hearsay is promoted as fact.

I agree, power failures don't generally cause hardware damage. Power surges
do.

If a UPS does this hardware protection, then you posted the
manufacturer spec numbers that makes that claim. Again you will not.
Recited myths made so popular by hearsay and advertising is also not
relevant to the OP's post. OP is asking about write-caching. Why are
you posting lies that are also not relevant?

A UPS has only one function. Temporary and 'dirty' power so that
unsaved data can be saved. What is some of the 'dirtiest' power
electronics see? Power from a UPS when in battery backup mode.
'Dirtiest' power also causes no damage due to superior protection
already inside every computer. Facts you should have known. And that
have no relationship to the OP's question about write caching.

The apparent anger in your response has blinded your ability to comprehend
the gyst of my conversation. I was not only discussing power failures but I
also mentioned surges on the order of lightning strikes. I was not
reponding to the OPs question about write caching, I was responding to pjp
who noted that they have experienced multiple power failures. Do you agree
that a power failure could cause you to lose unsaved data ? In that
particular case, do you still reject the use of a UPS to provide enough
power to allow you to save the data ?

Also, I disagree with you. The UPS I use (manufactured by APC) has (per
their claims) at least two functions. 1. To provide battery backup power
(dirty or not) when AC voltage drops too low and 2. Surge supression from
the likes of lightning strikes.

choro - your concerns are relevant. Dirtiest electricity comes from
a UPS in battery backup mode. Electricity so dirty as to even threaten
small electric motors and power strip protectors. Even that dirtiest
electricity made irrelevant by protection always inside computers -
even the original IBM PC.

The "protection always inside computers even the original IBM PC" is called
a fuse. I as well as others would find it hard to believe that my computer
is better able to handle a lighning strike than the UPS. You say it is?
Yeah, it would handle it........by frying every electrical component and
hardware device in it.

Have you ever heard of individuals being electrocuted through their
telephone lines when they were on the telephone and lightning struck ? I
know, that is just retail propaganda by a manufacturer.

As far as I'm concerned a $100 UPS is piece of mind for me whether it
provides clean or dirty electricity. I'd rather have 10 minutes of crap
electricity to save data then none at all and lose data !!!

Thanks a million. I've never used UPS and never really felt the need for one
though I do use surge protectors. Don't know whether Belkin still do this
particular model which also serves as a plinth to raise the monitor screen
around a couple of inches from the desktop and which comes equipped with 4
to 5 electrical sockets at the back with on/off switches at the front + a
master switch. What is more there is a thru unswitched power outlet which
comes in handy for things like a phone that must not be switched off
accidentally. I just use the master on/off switch to turn everything on or
off in one go. Brilliant. I've got several of these plinth type Belkin Surge
Masters. Use them for my hi-fi, in my bedroom for the alarm clock/radio,
digital DAB radio, bedside lights, phone charger etc. Immensely practical.
I'd recommend them highly to anybody.

My guess is that you never used a UPS or felt the need for one because
you've never lost data to a power failure.

Try this:
1. Work on your computer and spend 2 hours on important data.
2. Trip the circuit breaker to the computer
3. Wipe the tears from your face because you just lost important data as
well as 2 hours work you will have to redo.
4. Now wonder why you didn't have a UPS to give you time to save your data.
Surge protectors alone won't do that.

Westom offers a very, very weak argument not to have a UPS. It seems that
he(she) is even against surge protectors. Are you willing to give up your
surge protector because of westcom's remarks ? Would you still recommend
them given westcom's remarks.

I get your point. But as far as I am concerned the Belkin plinth is a very
practical and logically laid out "strip" (extension socket in the UK) with
anti-surge protection thrown in. You get the actual specs with the strip and
Belkin have got various levels of surge protection. To be honest, the
anti-surge capabilities do not much interest me but I'd still recommend the
Belkin plinth type Surge Master for its sheer practicality. I paid £8 for
mine (US$12) and I think I got my money's worth. I could hardly have bought
a normal strip with individually switched sockets for that much. I am
certainly not complaining though I don't know about people who paid the full
whack £60 ( = US$90!!!) when this model first came out.

The blob says it will sacrifice itself to save your equipment. And to be
honest I wouldn't be sorry if my equipment went up in smoke in the case of a
lightning strike as they provide a free insurance for any equipment
connected to a Belkin Power Surge. (Even though I wouldn't really trust the
insurance company to cough up the sum. They are masters of evading paying
out claims. To me insurance companies are the biggest crooks in the world!)

Yes, I must say that I always had my doubts how such a flimsy electrical
circuit could stop the effects of a direct lightning strike which would
probably bring the roof down! ;-)

But in life we have got to learn to take things with a pinch of salt! Still
any protection is better than none at all. Would you agree on this score?

to be), and for proper system shutdown when the power outage is long.

Which is also called time to save unsaved data.

No, not the way I use it. Your fixation on saving unsaved data is pathetic.
/I/ don't use it for that. I use it to turn my desktop into a laptop, so that
occasional power breaks of less than 15 minutes don't make me stop whatever I'm
doing. In addition, (as probably every advanced user should do), my internet is
powered by the UPS too, so if I'm doing something online, and the power
interruption is local, I don't have to stop that either. And the low-power desk
lamp is powered off the same. If /you/ chose to still live in the dark ages,
it's not my problem.
As to the hardware protection - you're wrong again. My UPS has en explicitly
stated warranty of $50,000 connected equipment if it should be damaged by a
surge/strike. While maybe it won't perform any better than the equipment itself,
it is a nice insurance to have around.
While your main objection that the UPS will not make any difference as to
write caching is quite valid, and answers the OP's question, using the UPS will
eliminate any need to even think about it as a problem.
Please learn how a normal user uses UPS.


Please learn how a typical UPS works. When not in battery backup
mode, then the UPS connects a computer to cleanest electricity - AC
mains. How does that relay inside a UPS stop destructive voltage
increases? It doesn't. But the myth sells a UPS to many who do not
ask damning technical questions. And who also ignore manufacturer
spec numbers.

In the 1970s, design standards required 120 volt electronics to
withstand voltage increases up to 600 volts without damage. Today,
those numbers for computers are even higher. You knew these numbers
before posting? No?

How often are you replacing dimmer switches, digital clocks,
dishwasher, and your furnace due to these voltage increases? You are
not. Excessive voltages are myths that promote retail sales. If
destructive voltages exist, then you are replacing bathroom GFCIs
daily. So what does that UPS protect from? Junk science
fabrications?

UPS outputs some of the 'dirtiest' power a computer will see. Power
that can harm small electric motors and power strip protectors is
still ideal perfect power to all computers. Computers are more
robust.

Meanwhile, these UPS protection fables are irrelevant to the OP's
question about write caching. That unsound concern is also solved by
the filesystem.

I have just responded to Weston. You can read my answer to him about Surge
Protectors. Yes, I'd still buy them and recommend them, particularly the
ultra-practical Belkin model I have got, because any protection no matter
how weak is better than none. And they hardly cost more than non-Surge types
of strips with individually switched sockets these days. But AS strips were
certainly way overpriced when they first appeared on the market years ago.

I can see your point re UPS. But living in the UK I'd still not buy one
unless my life depended on it. And then I'd buy the best one I could with
specs far above my requirements. I'd look for a factor of at least 3x to 5x
over my needs. And here I am talking in addition to the manufacturer's
margins.

I know that price doesn't always relate to quality but I'd certainly try to
buy a quality product. I don't believe in being tight-fisted where things
one is going to use for years and years are concerned. And I can well
imagine some cheap and nasty UPS units with no other merits except low
prices. That, as far as I am concerned, is false economy.

This computer that I am using is still going strong ten years after I built
it and it will probably outlast a good many of the brand new desktops and
laptops being sold today. Simply because it was built using quality
components. And in ten years it has only needed two or three fan
replacements. I have very recently built a new desktop, a "Speed Demon", as
somebody has called it and again I have used all quality components.

Buying cheap components is false economy. The same applies to UPS units. I
hope I have made my thinking on this matter clear.

As I live in very rural area, I've had many power failures. Usually only

hardware issues because of it. Last one lost a video card and hard disk
started becoming suspect also. Laptops kinda nice for avoiding that kinda
problem as
they seem to switch fast enough to battery.

Don't you have an uninterruptible power supply (UPS)? It's enitre purpose
is power failures and surge protection. It would (almost) eliminate the
possibility of losing hardware or data.

Nope, had one awhile ago but it was a very old very heavy duty job not used
at work. Found out why, damn thing had the loudest hum. I took it back to
shop after just few days. Kinda wish I'd kept it because could have always
put it "someplace else" and run power from it to where needed. Biggest
problem here is the number of pc's scattered thru house has been as many as
9 at any one time, across three floors. Makes just one affordable ups not
meet needs. Easier to just use laptop during storms etc. and well can't do
much about someone taking out a lamppole at times. I'll add that when the
power goes out is not usually the problem for most things. Seems to be when
it comes back on and more specifically when they try to have it come on but
it goes off to come back on to go off cycle a few times is the biggest
problem times. Have lost VCR's, DVD players, TV over the years. Seems more

You described a UPS doing its only function is - to save unsaved

unsaved data. Why are you arguing this while agreeing with me?

That warranty demonstrates that lying is legal. Did you read the
many fine print exemptions? One APC exemption said any protector from
any other manufacturer in the building voids their warranty. These
many exemptions so that a warranty will not be honored.

Manufacturer protection specs again were not posted for one glaring
reason. You could not find what does not exist. Obviously. Missing
is an always required 'less than 3 meter' connection to earth.
Specifications make no effective protection claims. It does output
dirtiest power 15 minutes (or less) to protect data – its only
purpose. Which does nothing for write caching and why the UPS should
have never been mentioned.

Will you find those spec numbers? Or just post more hearsay
denials?

A majority believe obscene myths such as that $50,000 warranty.
Please read fine print exemptions. Or read so many other's
frustrations to submit a claim. Where does it list protection from
each type of surge? Read numeric specifications. Not quoted here for
one glaring reason. It only does protection when naive consumers
recite what they are told to believe. When they do not ask damning
questions. When they ignore numeric specs which you still do not

The Belkin warranty is reams of find print exemptions. Consumers
quickly learn that a big buck warranty is often attached to the most
inferior products. For example, GM is promoting warranties far
superior to anything from Honda, Toyota, or Hyundai. Does that prove
GM products are better? No. That suggests that GM products are
inferior.

Or learn from other's experiences. Newsman in "SONY TiVo SVR-2000"
described jumping through many hoops to have that claim repeatedly
rejected. He summarized that Belkin warranty in his last sentence:
[quote]Eventually it boiled down to a line in the warranty that said
"Belkin at it's sole discretion can reject any claim for any reason".[/
quote]

MersyBeat apparently did not grasp what was posted. The UPS has one
function. To provide temporary and dirty power. So that unsaved data
can be saved. Hardware protection is implemented elsewhere and for
less money. Neither that Belkin nor UPS do or claim to provide that
hardware protection. And both are relevant to write caching for a
hard drive.

Remove combustible materials adjacent to that Belkin. Or earth a
'whole house' protector to protect that Belkin and everything else.

i have write caching off - still works fine (made windows more reliable
than it was in dos days). With laptops power failure is not an issue
with good battery.
