Something Different

That you had it completely wrong is immutable fact - not an option.

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 .

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.

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

The thread had diverged from that.

Irrelevant to the general question about whether wood, like any insulator CAN BE a conductor.

No such animal.

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

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.

Its you that need to do that.

The point being d*****ad? 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:

"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 * d*****ad . Its the only software used in courts in the US .

You sure havnt got a clue fool .

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.

Dont need to, the term 'clone file' isnt commonly used.

Irrelevant to the use of that term, f****it.

Nothing like what you originally pig ignorantly claimed.

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.

Wrong, as always.

So does Drive Image, Ghost, True Image, xxcopy, xxclone, etc etc etc.

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, f****it.

Duh.

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.

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.

Pity that the most common use of cloning doesnt need any audit.

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.

I have also seen lab tests on dry timber.

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.
