    Need some advice? CAR PC Short Life

    I just creamed my hard drive and cd-rom on my carputer in an unfortunate short stop and pothole incident. The hard drive has become so damaged that it is not even being detected and the cd/dvd-rom is not reading discs properly. The mobo ps and everything else works fine. I enjoyed my car pc for almost exactly 2-3 weeks. ;p. Problem is I drive a Hyundai Tiburon and drive thru the streets of all 5 boros of new york. Anyone that lives or visits here knows a carputer is playing in dangerous waters with all of the *****ed up streets and potholes. This winter inparticular has done quite a toll on the roads here. I can only assume many others have experienced problems like these. What are people doing for mounting of hard drives etc? This single incident alone has me wanting to just sell off everything and drop the carpc project alltogether. I may have to wait out for solid state media storage. The PC didnt make it through 3 weeks and those 3 were pretty rough for the hard drive and cd-rom obviously.

    how was your hard drive mounted?

    I plan on mounting mine vertical as that should help a lot with bumps and whatnot.

    If your roads are that bad you may want to look into some sort of dampening system for the HD or the whole PC. Not something springy, you want to avoid oscilations ... but something that works like a shock to dampen the impact.

    It was mounted inside of a morex 3688 case. I experimented w/ both verticle and horozontal mounting of the case which meant the hard drive was mounted both ways. It crashed the least when it was horozontal but it was mounted that way when it came to its screaching death. It was velcro'ed to the back of one of the passenger seats in the back. I would fold down the seat while driving. The case was sitting on top of foam, which did not seem to help much if at all.
    p.s. it was a laptop hdd. I dont know if that would contribute to its failure being more sensitive and all.

    I've been running mine without problems for about 8 months now in Maine where the roads are loaded with frost heaves this time of year and my suspension is pretty tight. I have my laptop hard disk mounted horizontally but no screws just stuck to a 1/2" thick piece of sorbothene foam. Its never even acted up from a bump or just being cold. My touch screen is sometimes a little fussy when its been sitting in really cold temperatures for a few hours but other then that no problems.

    I notice that the suspension of a cd changer don't move that much because the unit is in the air hold by 4 oil suspension springs

    The idea is to take a defective cd changer out of the case and put the HD inside
    i hope it works i will let you know

    sounds like a good idea

    check it out http://cgi.ebay.com/ws/eBayISAPI.dll...39747.....Only 2 bucks. You can't beat that. Anywaz, what brand of hard drives does everyone have. Which ones seem to be the best, and which seem to be the worse. I've heard that some of the Maxtors have a type of fluid dynamic bearing that doesn't respond well to low temperatures. However, if you can find a maxtor without this I know that they seem to be the best product, and they offer the best return policy. (ie they won't ask you if you had your hard drive mounted in your car when it broke).

    My whole system is built inside of an old Nakamichi 7 disc changer. Works great. Holds an EPIA, 3.5" HD, laptop cd, Sproggy, and ITPS with room to spare. The drives are mounted to a tray that is fully suspended by 4 springs and rubber dampeners. I don't really think the suspension is necessary with a properly mounted case, but the changer chassis was too perfect and the tray was already there. The setup has already made it through the worst Utah winter in anyone's memory, so I think it's a solid design.

    If your looking for BB drives, instead of the FDB. A simple way to find out which is looking at the model number 4R060J0, this hard drive uses ball bearing, instead of the fluid. The J denotes ball bearing drive in the DIAMOND MAX 16 series. The 4R060L0, is an FBR drive.

    The Diamond max series 9 is wierd the 16 is much better documented.
