    Talking Idea to protect the hard drive...

    I'm currently building my mp3 player, and I was thinking about how I should protect the hard drive... One thought led to another, and essentially, I am thinking of making a suspension for the drive. Here's my plan:

    Put L brackets on the drive, so the screws attach from above instead of the side: _|==|_

    Mount the screws with springs between the head and the mount surface, the mount surface and the drive, and the drive and the nut:
    ^ <-- Screw head
    @ <-- Spring
    - <-- Case mount area
    @ <-- Spring
    - <-- Hard drive L bracket
    @ <-- Spring
    * <-- Screw nut

    Since it would be metal, it would maintain grounding, unlike rubber grommet mounting. Any feedback? Suggestions? Think it will work?

    i did something simmiler with my old system. but instead of having the drive verticle i had it flat and mounted on a small piece of wood. then i ran huge bolts to the top of the case and springs both above and below the piece of wood. the system was pretty slick and i never had a problem (plus i was driving through heavy construction and ripped up roads.

    the only problem was that it was too bulky. and well people say to have it mounted vertically.

    Im still thinking about this whole thing, I have been for a long time. One thing i noticed is i have never heard of anyone distroying there hardrive when it was in the trunk (from shock, ive heard that heat killed a few) granted its best to be safe then sorry but if it was such a problem wouldnt you hear more damage stories?

    Cool

    That setup works great to shock protect my whole player :-)

    If you want to go further, you could use the shock absorbers from RC cars...

    The hard drive in my unit is mounted vertically and bolted to the sides of the case. The case is bungeed to the side of the car quite firmly. Never had a problem with it.

    Come to think of it, I've never heard of anyone destroying a hard drive due to shock...

    Hmmm... Everyone's going vertical! What exactly does vertical mounting do?

    Come to think of it, I haven't heard of anyone damaging a drive from shock either. I myself dropped my hard drive caddy yesterday. Scared the $#!+ out of me because it had my 30 gig in it.

    The HD platters lie flat, and the heads float between them, just off the surface. If you bump the top or bottom, you could (at least theoretically) cause one of the heads to hit one of the platters causing physical damage (HD head crash)

    Most of the impact to your car (other than wrecks) is in a vertical motion.

    So if you mount your HD vertically, the heads if bumped up or down, will only move, they will not be forced into the platters.

    It makes sense but I have no idea if there is actual proof it makes a difference, but what the heck.

    However there is also some discussion that the constant road vibration (or subwoofer) will cause more damage than a pothole bump.

    When my player is working, and when it is installed, I have it next to my JL 10" Sub. I didnt take any precautions in HD mounting , I mounted it in the worst possible place, on the bottom of the lid for my case horizontally. I have been run off the road at 70mph , hit pot holes at high speeds, and dodged the occasional senile old person on Florida's turnpike, however, my hard drive has yet to show any type of wear. It is a western digital 3gig.

    This is exactly what i thought! nobody is having problems with shock inside cars. I mean i still have yet to hear about it! Plus these last few posts kinda prove contrary to everybodies beliefs about shock protection. Ive decided to have my hardrive mounted horizontaly but my system mounted virticaly (strap it to the side of my trunk (so yes the drive is verticle too) but other then that im not going to put any protection on the system. by the way that is a nice 45 gig drive that i am doing this with. Until i start hearing droves of ppl say anything to the likes of their drives getting massacred im going to keep it that way.

    Aaron i have to admit i do like you system mount. kinda interesting (nice for people to look at though) did you ever try adding a light inside the plexy case yet? i just think it would look cool.

    The mount works great, but will squeek if not oiled. I have thought about adding lights to the plexi case, but just never done it. On some levels it would be really cool, but on many other levels it would just be cheesy :-)

    ya the cheese factor on that is a bit high... maybe just to show off every once and a while but thats about it. im sure the novelty would wear off fast. Just wondering cause you system seems to be pretty much out in the open.
