    HDD shockmounts?

    Still in the planning stages for my carPC (currently a M1000 running Gentoo in my room), I was wondering if any of you know of any shock mounts that would work on hard drives. That is one of few fears I have while doing this carpc project. I am using a 250GB 7200rpm drive and can't afford to have it go bad just because of a bumpy road here and there. I thought about using a spare laptop drive I had (like some of you said you had good results with) but I need more space than that. I'm going to put mp3's a ton of SNES/NES roms and then copy music DVDs to the pc (concerts and whatnot). So I will eat up 40GB pretty quick.

    The only idea I have been able to come up with is to create (or find) a shockmount for a hard drive like the one I use in my recording studio for microphones. For those of you that don't know what I'm talking about it's basically a frame with a bungee cord and then the bungee cord attaches to the devices. This way there is no solid connection between the device and it's surroundings. It just 'hangs' in bungee cords.

    Example:
    http://www.musiciansfriend.com/srs7/...ase_id/106749/

    that is made so a small microphone can go in the center hole. The two bars coming out on the bottom are just to tighten and loosen the hold for the mic and not needed for a hdd.

    Any ideas where I could find something like this? or what have any of you used that worked well?

    no those are pointless.. i had a normal drive screwed right into my case for 3 years with no problems. If you want something use a rubber stopper.. don't waste your cash

    The other problem with those types of shock mounts is when the HDD hits the casing from a particular rough bump you will likely cause more damage to the drive than if it were mounted solidly. Like HiJinks said, save your cash and use a bit of rubber.

    Happy Carputing.

    There is a "proper" shockmount. This is a HDD frame with elastic to support the drive in an isolated fashion. it was meant to "de-couple" the HD vibrations from the PC to lessen the noise, but I imagine that it will also "de-couple" the car vibrations from the drive.. http://www.ichbinleise.de/product_in...roducts_id=289

    Looks like that would not be much better than a typical mount - since any real shock will cause it to bottom out - may be worse in a car. Also most have recommended that the drive be mounted vertical or one it's side to minimize the damage from a head crash. Laptop drives have better resistance to shock. Just my 2 cents - I just got my carputer installed (fit it all in the dash) - hdd is a laptop one mounted sideways with rubber gromets to reduce the vibration.

    i would think that the bungie cord product is even worse than having the hard drive hard mounted. what is happening is that basically, you've added springs to a suspension system but no dampener. the suspended object will oscillate back and forth until it comes to a halt by itself. what you need is a dampener in that system.

    Shockmounting can add bounce or harmonics to the motion of the drive.... this is very bad for the HD.

    Do not shock mount... This has been hashed out many times (searching would have told you that)

    Yes, you should search... and Yes, It has been covered before!

    Actually that shockmount is what I was talking about creating... Just didn't know anyone had done it yet.

    I can see it now, going over a hill, (the ones that make your stomache go) and then having the drive go up and down forever, or even bottoming out and causing the platters to crash. Try mounting it horizonatally.

    The way the shockmounts for mics are made (and what I was planning on making) doesn't let it bounce a lot. The cords pull in both directions so if it does move it stops fairly quick. It just smooths out the sudden jolts. You probably wouldn't even see it move unless you hit one of those big potholes (the ones that make you wonder if your tire is still intact).

    But if nobody has had problems with bumps then I won't worry about it.
