    Anyone use these bags to protect from electromagnetic waves? For laptops, seperate drives, etc. Like placing a hard drive inside one or two of them.

    I've noticed where some are used by the department of defense, but are the private bags for consumers actually tested to withstand?

    Relaibility, a huge question.

    Sounds pretty worthless to me. They would help an ordinary PC owner only in the event of an EMP such as results from a nuclear detonation. And if THAT happened, you've have FAR more to be concerned about than the data on a hard drive!

    There is also the case of the solar flare.

    The largest solar flare we've ever experienced (sorry, can't remember the date) had absolutely NO effect on personal computers.

    Pardon me for pointing this out so bluntly, but the people selling these things are relying on ignorance and fear in the general population to lead them into buying them. In a word, it's nothing but a scam.

    One of the stories in my family legacy is from 1859 when my great great grandfather Otis lost all of his data. He had this awesome Macbook at the time, and nearly .0000000001 bit of really important data that he couldn't afford to lose (that was a lot of data for those times). All of a sudden, a bunch of sparks spontaneously flew out of his Macbook, and no matter how many times he tried to turn the crank to make it boot, nothing would happen. I think that was the first year they made models without cattle or steam powered hard drives.
    That disaster cost him his livelihood. He soon lost his life savings of 40 dollars, and was forced to move out west where he died of tuberculosis.

    dude you cant have .000000000001 bits, a bit is either a 1 or a 0 so how do you have .0000000001 of A 1 or A 0

    It was a quantum computer.

    That was very interesting, thank you.

    But coming back to your original question...

    If you feel compelled to throw away your money on the off-chance that something that MIGHT happen every 150 to 500 years (and probably much longer than that) is going to recur DURING your lifetime, then go ahead and and buy those bags.

    In the meanwhile, though, I'd advise you to stay out of casinos since figuring odds and probabilities doesn't seem to be your thing.

    So I take it that my SF brothers aren't currently using the bags!

    Some of the replies are leaning toward sarcasm, almost! But aren't the military using these types of things, along with hardened electronics -- for a reason? And isn't NASA predicting we are entering a stage of high solar activity? That is, if their word means anything.

    But there's another important question here aside from the original question and that is -- do we really need past disasters in order to prepare for what may rear its head in the future, without getting paranoid? If that's true, again putting the 'bags' temporarily aside, then we might be in trouble in different areas.

    But, thankfully they'll be people like Otis to lead us.

    Even at the minimum, our power generating stations should be hardened, which they are not. Something Newt Gingrich was is in favor of. Haven't heard anything from the other two.

    None of the military computers that I have been on have them.

    Apparently you don't realize how you're making yourself look here. Much like a guy with a single tree 1000 yards from his house that he's afraid is going to fall on him. Sure, there's probably something like a 1 in 10 million chance that a tornado MIGHT pick up the tree and JUST HAPPEN to drop it on his house. Shucks, the odds are much higher that one morning he will trip while getting out of bed, fall and break his neck killing himself.

    Newt was bit foolish also. The power generating stations themselves are in little danger - it's the transmission lines that are at risk from a powerful solar storm.

    And I've NO idea who this "Otis" or "the other two" are that you're talking about. <shrug> Means nothing to me.

    You are obviously entitled to your own opinion. Although your analogy has the relevance of someone really groping for something, whatever that is. To be fair, you may think its me!

    Forget Gingrich, if you're that sensitive to him.

    So speaking of facts -- where do you get the info that the power generating stations are "in little danger"?

    If you're that worried just burn the data you don't want to lose (like family photos?) onto a blueray disk and store it in a vault with your other precious stuff (like gold and silver

    My "opinion" has nothing to with it - I AM talking about facts. And I'm not groping for anything, it's you that's lost and blowing around like a leaf in wind. Also, I have no "sensitivity" to Gingrich in any form. What you failed to understand about his statement is that he was talking about possible damage to generation plants from terrorist's attacks, not solar activity.

    But the interesting thing about this post (and all your others, for that matter) is that you've finally revealed your problem and have shown why everything I've explained to you has gone right over your head - you do not understand the first thing about electricity, electromagnetism and induction. For example, in that article about the 19th century event, you again failed to understand that it was NOT the telegraph stations themselves that were directly hit and affected by the storms - it was the hundreds of miles of telegraph LINES that captured the energy by INDUCTION and carried it to those offices.

    And if you've been paying attention and had ANY grasp of those basic principles of electricity your question about those bags would have been resolved long ago.

    Perhaps you are not yet old enough to have covered the subject in class yet or simply slept through them and learned nothing. There's no way for those of us here to tell which. But in any event, I suggest you do a little basic research - you'll find it to be very helpful in understanding this and many other things as well.

    You seem to be getting more than a little carried away here. Your tone, the accusations, etc.

    Electronic circuit boards would likely be affected any way you look at it.

    As far as Gingrich I simply said that he was in favor of hardening, which you've intepreted into something else.

    Let's tone things down a bit, eh? Otherwise please don't respond.

    I have NO interest in "tones" - up or down. The only thing that interests me in the least is facts - and that's exactly what I've given you on each occasion and you seem to be ignoring them.

    Look, there's no problem with not knowing something, none of us was born knowing everything, and what we know we had to learn at some point. However, there IS a problem when someone is dishonest and pretends to know facts that they do not. So I would still advise you to go do a bit of studying.

    Enough Read-Only. You and your ridiculous statements.

    There's nothing ridiculous about ANY of my statements - they all reflect facts.

    And speaking of facts, why don't you come clean with us and admit you're just a slightly uneducated kid? You don't appear to be an adult in any kind of way. How about it - afraid to be honest?
