In Law Enforcement an image or clone file is created FYI .

Its an exact sector copy of the entire hard drive and there are loads of 3rd
party apps that do the same and reproduce this on an identical physical or
logical drive .

How did I have it wrong ? , I think your wrong in your conclusions . Have
another go on this most basic of topics .

Yes it is.

It is if the wood is wet. Take a look at any photo of a lab strike to
a dry peice of timber. The lighning travels around the outside of the
timber. Put a piece of plastic next to the piece of wood, and the
plastic will also produce the same effect. I beleive the term is
called flashover. The same phenomena affects ceramic insulators.

So pray tell what it is that does the conducting?

And don't say electrons, because by that logic metals wouldn't be
considered conductors.

Me thinks you should go back to physics and chem 101. Or maybe better,
go back and start in say... year 10 or 11.

I thought air was a good insulator too. How does ligning travel
through air? I beleive the term is called ionisation.

Well in the context of grounding a laptop,

The thread had diverged from that.
wood is useless and would act as an insulator.
In the context of the 'bandstand' incident,
water was the conductor - NOT wood.
In both instatnces wood was/is not a conductor.

Irrelevant to the general question about whether
wood, like any insulator CAN BE a conductor.
Somehow we diverged to the Geelong incident. The lightning
was conducted by water from the thunderstorm - not the wood.

Irrelevant to the general question about whether
wood, like any insulator CAN BE a conductor.
Which was the situation where water was the
main conductive substance - NOT the wood.

Irrelevant to the general question about whether
wood, like any insulator CAN BE a conductor.
You said wood was doing the conducting - it wasn't.

wood, like any insulator CAN BE a conductor.

No such animal.

How did I have it wrong ? ,

You claimed that an image file is always involved. You are wrong.
I think your wrong in your conclusions .

Nope, as I proved with the example of an almost full hard drive being
cloned to the same sized drive, there is nowhere to put the image file.
Have another go on this most basic of topics .

Its you that need to do that.

The point being dickhead? Its not the material that is conducting the
lightning, it is only assisting it. It is ionised air that conducts.
So the answer is no, the wood is not conducting electricity.

Here: http://wvlightning.com/trees.shtml

"Electricity seeks the path of least resistance, and the moisture (sap
and water) inside a tree is a much better conductor than air. The
result: a tree provides a preferred path for lightning to reach ground."

Now for the trick question: what contains the sap and moisture?
The answer starts with a "w" and ends with a "d" and has four letters.

I expect you'll now try to play with definitions about wood moisture
content or something.

I was gunna opt out of this thread but I have to clarify a point or two.

The people under the bandstand were covered by the roof. Now it may have
been that the strike ionised the air all around, and inside, but I
guarantee that the wooden structure (mostly dry - it had a roof
remember) was also a path.

Have you ever seen a large tree split in half by lightning? What has
happened? Think about what forces are occurring in that tree to
literally blow it apart. What is it that has passed through the wood, to
cause, I assume, a large build up of gas?

I get the feeling that a few otherwise intelligent engineers, techs etc,
don't quite appreciate just how powerful lightning is...

Check out * encase * dickhead . Its the only software used in courts in the
US .

You sure havnt got a clue fool .


You claimed that an image file is always involved. You are wrong.

Its an option and it * depends * on the software used . You only use True
Image , sure its does on the fly cloning but thats only one small option for
cloning drives , there are 50 products out there and your speaking about 1
thats not used by the professionals . Why take an image if its not a backup
and repeatable on the deployment .Also a file is much easier to audit for
backup retrieval , rather than a physical drive . This argument is typical
homeboy stuff.

Wrong, as always.
It is ionised air that conducts.

Sometimes it is, sometimes it aint.
So the answer is no, the wood is not conducting electricity.

Wrong, as always.

Check out * encase * dickhead .

Dont need to, the term 'clone file' isnt commonly used.
Its the only software used in courts in the US .

Irrelevant to the use of that term, fuckwit.
Its an option

Nothing like what you originally pig ignorantly claimed.
and it * depends * on the software used .

Wrong, as always. There is no image file involved with a clone
of an almost full hard drive to a drive of the same size when using
Drive Image, Ghost, True Image, xxcopy, xxclone, etc etc etc.
You only use True Image ,

Wrong, as always.
sure its does on the fly cloning

So does Drive Image, Ghost, True Image, xxcopy, xxclone, etc etc etc.
but thats only one small option for cloning drives ,

Its the ONLY option possible when cloning an almost
full hard drive to a drive of the same size because
there is nowhere to put the image file, fuckwit.
there are 50 products out there
Duh.

and your speaking about 1 thats not used by the professionals .

Pity its also true of Drive Image, Ghost, True Image, xxcopy, xxclone,
etc etc etc when cloning an almost full drive to another of the same size.
Why take an image if its not a backup and repeatable on the deployment .

What matters is whether its FUNCTIONALLY identical.

There are significant downsides with sector by sector clones,
most obviously that the two physical drives need to be identical.
That is NOT the situation in which most cloning is done. Its MUCH
more often done when upgrading the boot drive to a new bigger
drive and a sector by sector clone wont work in that case
because the clone will be the same sized as the original, stupid.
Also a file is much easier to audit for backup
retrieval, rather than a physical drive.

Pity that the most common use of cloning doesnt need any audit.
This argument is typical homeboy stuff.

Couldnt bullshit its way out of a wet paper bag even
if its pathetic excuse for a 'life' depended on it.

There was no general question, it was in relation to a specific incident.
You diverged from what was being discussed and now you claim that your
divergence is right.

In context, you are wrong.

I beleive i have already quoted elsewhere a 'dry' piece of timber. I
beleive that the article you suggest also specifies 'sap and water'?

BTW. I have seen the results of dry, seasoned timber in lab lightning
tests. I can assure you that a 'dry' peice of timber will not conduct
any better than a piece of ceramic.

Some recent research has suggested that the rare positive ground
strikes can be upto 6 times more powerful than is commonly believed.
Likewise, the sprites from positive CG strikes have only been really
discovered in the last ten or so years, and a sprite projects 90km up
into the atmosphere. That's about 60-70km above the higher clouds. not
bad when you consider the average ground strike is only around 10km
max.

I was watching a doco that other night that made a suggestion that
space shuttle columbia crash may have been a result of a positive CG
strike.

Plenty of dry wood in a thunderstorm.
