    UG seriously, we are going to do this again? 2.5" HD typically are rated for higher shock than 3.5" drives. AND so nobody can flame me... here are two PDF's from Western Digital proving it. First is 3.5" WD Caviar Blue, Second is 2.5" WD Scorpio Blue. Both are of the same "series" AKA BLUE but 2.5's are scorpio and 3.5's caviar... I digress.

    3.5" 30 - 65 OPERATING Gs or 300 - 350 non operating
    2.5" 350 - 400 OPERATING Gs or 900 - 1000 non operating

    BIG difference so it can't be said that caviar and scorpio are apples/oranges in series'.

    Sure, How many Gs of shock are the driver and car rated for? Book specs are great, they are not proof one is better than the other in a car. Not disputing your numbers or the factory specs at all.

    If you have been in any other HD threads you will have read my personal history with wrecked cars, bent frames and a desktop drive that is still functioning after being in use when the frames (boxed ladder type and yes, plural) bent.

    Deal with it.

    A far more likely cause of HD failure in a car regardless of form factor is poorly regulated p0wer. Nope, I can't 'prove' it or change your mind. But you cannot disprove it either.

    I never disputed if a 3.5 would handle the g's of the road or an accident. Surely the hard drive is rated for more g's than a human body. I simply pointed out my statement was in fact FACT.

    A 60 mph crash with a stationary object will have around 30g's (assuming .1 second deceleration time)... at that point the human is not feeling well if anything at all and even the 3.5" hd is still within spec. So, you are correct; the only proven reason to go with a 2.5 over 3.5 would be size and power consumption. But, if I had a 3.5" drive or a 2.5" drive to choose from all things equal... I would take the 2.5" because it will by definition handle the stress of the road better in edition to its reduced size and electrical consumption and increased speed. Would I pay more for it? No.

    The fact that you have wrecked multiple cars(as I gather from your semi cryptic statement) with a hard drive on board proves little other than you are lucky and likely either a poor driver or an odd combination of lucky and unlucky at the same time. Certainly not dissing your driving skills, but without further details I have little to go on.

    There is a reason IBM and other manufacturers put effort into parking the heads on their hard drives when a laptop detects it is free falling. Probably not because their research said you were guaranteed to loose the hard drive but rather it wasn't worth the risk.

    Not sure about the spoon... some weird matrix joke or are you trying to be rude? Either way you can keep it.

    If you two want to argue about the merits of 2.5 vs 3.5 drives, go ahead, however it is out of scope for the topic of this thread, so you might do well to create a new thread to do so rather than clutter up this one. This guy is using a laptop, he's kinda limited to a laptop drive, regardless of which is better.

    This is one of the things i have been thinking about. I plan on soldering a wire to the power button on the laptop. What I cant decide on is if I should just put a button on the end of it or find a way to use a relay and have it activate for just a second.

    It has a VGA port on the side. And with the ATI graphics manager I can tweak the size down to what I want.

    From the laptop to a Clarion EQS-746 EQ then to the amps.

    Ive tested Centrafuse over the past couple of days on that laptop and it seems to work fine without any lag.

    The screen looks great. I love the LED backlighting on it. It looks like it should do fairly well in sunlight. I will probably hold off on installing the anti-glare shield until I test it and see how it does without it.

    Need a Sandy Bridge-E 6-core to run CF with any decent speed. Oh, and the fastest SSD you can buy.

    lol, That bad? I've never run CF other than on my core2 desktop for trial. My atom runs RR & dashcommand just fine. I have heard that certain skins will kill an atom in RR though.

    There is a circuit you can build here: Laptop Auto Power-On / Turn-On Module
    You could get a standalone shutdown controller like this one: http://store.mp3car.com/Micro_Shutdo..._p/pwr-007.htm

    Shutdown controllers are good safe option though as they usually have fail safe built in so that it will kill power even if the computer hangs. This will keep your battery from A) draining and B) deep cycling.

    Just ordered the microshutdown controller from the mp3car store, thanks for the advice
