    HD's and vibrations

    i know hard drives dont like to be moved around alot while there in operations..

    so how well do they survive in a car? have people put any anti shock protection around it??

    and has anyone got theres next to a sub boX? where i will mount mine for ease of access will be next to a sub box.. and its a laptop

    does anyone wana talk me out of puting there and finding somewhere with less vibrations like under a seat or something..

    the install will be going in a dule cab pick up.. so there is no boot to put it in,

    i believe some people have put them in a sub box. Your normal drive can take a lot more beating then you think. DON'T USE ANY SHOCK SYSTEM! if you wrap it in foam the drive will over heat. I screwed mine right into the case like a normal drive and it lasted 3 years. I'd even have it on while off roading. I would think if you put it in the sub box don't mount it close to the sub due to the magnectic field

    I think this should be qualified somewhat. Don't use any shock system UNLESS you know what you are doing. You can make things a lot worse. The key points are to not introduce oscillation, and to not inhibit the cooling of the drive.

    I have used a shock system for over 4 years now, with no problems at all. I use stiff rubber grommits that take the harshness off any shocks, but don't allow that much movement.

    IN the sub box. That's a crazy way to do it. And I'd love to see pics because I'm kicking myself for not thinking of it.

    I use a mobile hard drive out of a laptop. They are smaller of course and are used in a lot of mobile mp3 players as well. The archos uses laptop drives for it's storage and it says you can use this as a walkman while you are jogging or anything. So my guess is it is ok in a car as well.

    Just curious, Rob. How did you do the grommits? I was going to use a gel pad for shock absorbtion, but it doesn't fit in my enclosure. So I picked up four grommits from the hardware store. I'm not sure how to best use them.

    Should I sandwich the grommit between the drive and the case, and screw it down snug? Like in my primative drawing?

    Something with that idea just doesn't sit right with me. It seems like the shock would travel up the screw to the drive, regardless of the grommit.

    Thanks,
    Tom

    Mount that biatch like any other drive and you should be fine. The only other recomendation I would give is mount it on it's side to try and help avoid the heads from getting hit from hard bumps.

    Ive used a hitachi travelstar 2.5" drive in my old carputer setup and that thing never skipped a beat. I was ridding on 225,45,17s and stiff *** coilovers. I had no cooling on it or "shock protection."
    Mine needs to be updated.

    Tom,

    Get rid of the washer, drill a bigger hole in the case, and mount the groument between the outside and inside of the case wall.

    What you show in the drawing is a gasket and not so much a groument. you want the screw to float in the rubber groument.

    The way you have it now won't do much. You can also purchas a shock mount for the drive. Search google for "vibration hard drive mount shock" There's also a forum post with a link.
