I've had devices fail, a Tivo and a fax machine. This was due to a surge.
Since the utilities are buried for the last 1/2 mile to my house, and I did
not have a direct hit on the house this was not a failure due to a direct
hit. Yet, according to you, the built in protection should have worked.

Problem solved!

Take a few minutes to execute another Windows utility that would/
should have solved the problem. Find the Disk Manager – found in many
placed such as Computer Management under the name Disk Management. If
necessary, use Windows Help to load it. This powerful utility is for
the problem you were having. Learn about it now so that, if you need
it, you understand it.

You said I have posted contradictions. I suggested you don't have
grasp of the basic concepts. Well understood is that direct lightning
strikes to appliances can even be via buried wires. IOW those
contradictions are traceable to facts you have not yet learned.

In a similar example, lightning struck a nearby tree. Therefore the
horse standing 25 feet away suffered a direct lightning strike. Why?
Again, learn how surges work. Lightning was seeking a shortest path
to earthborn charges 5 miles away. So lightning traveled 3 miles down
to a tree, then four miles through earth to complete an electrical
circuit. A shortest path through 4 miles of earth was up the horse’s
hind legs and down its fore legs. The naive said the horse was not
struck directly. False. Another example of a direct strike to the
horse (or to household appliances). But those who did not first learn
the science - who only knew by what they saw - never learned why a
horse was killed by a direct lightning strike. BTW, golfers suffer the
same threat - death by a direct strike that did not strike his head.

Lightning striking utility wires out on the street are a direct
lightning strike to appliances ... if properly earthed protectors are
not installed.

You thought buried wires are protected? Just another example of why
you have not yet grasped basic surge protection principles. If you
were correct, then the above horse was not killed by a direct
lightning strike via the nearby tree.

Your question is admiral – an example of how one wants to learn.
But your accusations are typical of one who knows without first
learning facts.

I never said the built in protection should have worked for direct
lightning strikes. But you did not understand that the Tivo, et al
could have been victims of a direct strike to underground wires.
Again, you knew without first learning so basic facts about surge
protection.
