    So close..yet so far

    Well this sucks...

    a few weeks ago my computer was giving me a lot of problems:
    Carputer Hard Drive Crashed..help
    (basically, the harddrive failed, and newegg ended up giving me a refund)

    well, I just bought a new 160 gig maxtor off of tigerdirect with the money newegg gave me for the refund. Took my carputer out, installed the harddrive and set up winXP and all my programs, put the computer back in, and it works fine for the hour or 2 I used it last night. Then later today, I go to turn it on, it runs for 5 mins...and it locks up with the same clicking sound described in my previous thread.

    How is it possible that 2 hard drives have failed on me? I really don't think it is...it has to be something else thats giving me problems..

    What puzzles me even more, is that if i take the carputer out of the truck, it runs fine...if i put it in...it locks up EVERY time within 5 minutes.

    This sucks...I'm just about to wrap up my whole project (minor details left..about a week of work) and now I can't even use it.

    Any ideas/suggestions?

    Right now I'm considering ditching the whole computer and just buying a laptop like I should have in the first place. Hopefully I can keep my laptop budget under $800.

    Or, I guess I could try a laptop harddrive and see if I have better results with that.....I just hate to spend more money and time on something that's not going to work right.

    How are you mounting it etc??? Its odd to have two HDs fail with the same problem like that..... We need more info.

    Can you yank that HD and put it in a different PC and see if it works? More testing is needed.

    the harddrive is mounted vertically, solid to the case. I know some people are using shock protection, but I read that other people were suggesting to mount it solid, as to reduce the vibration that shock protection would add.

    I've taken that harddrive out and put it in another machine, but it doesn't boot off it...I think due to compatibility issues. If i plug the drive into a computer via a USB-IDE cable, I can read all the data fine, without any problems.

    At least if I knew it was the drive, I could send it back...but I'm worried that I could put another drive in, and have the same problem.

    sounds like a power overload.... what system are you running & what power supply.... if you have a seperate 12v supply try running the hardrive off that to see, or try taking other stuff off the 12v rail...

    specs:
    asus motherboard
    2.8 p4
    1gig of sdram
    160 gig harddrive

    I have a 380 watt powersupply running off of an 850 watt inverter. The only devices I have plugged in aside from the hard drive is:
    computer case fan
    processor fan
    usb mouse, keyboard, and GPS reciever
    1 serial remote control receiver
    a dvd rom drive (usb, but it has a seperate molex connector going to it)


    I should add that i tried unplugging everything (all the USB devices, the serial device, sound, etc) from the system except for the monitor and the mouse inside my truck.....and it still locked up.

    I'm running the computer right now in my basement, with the powersupply from my truck, and it's running great.

    the inverter may say 850 watts, but somwtimes inverters are rated like amps & are way overrated , & it may not be able to provide continuous power for the pc....

    when a hard drive does that wir, click, wirrr, click.... it's usually power related...

    go ouyt & get a 1,500 watt inverter... you'll be o.k. then, as long as your alternator can keep up......

    that p4 is a power hungry heat spewing monster, & you need power

    ... then you still may have issues when you crank the car......

    at this point your learning why a p4 monster & an inverter is not really the best way to put a pc in your car....

    as long as the battery & alternator are strong you'll be ok with a larger inverter... try it & see if it is good enough for you at this point...

    if you do decide to do it over stay with a low power mobile design & a dc/dc power supply, you'll be much more stable....

    you might want to get the dc/dc ATDSX powersupply, it can handle that load i belive. and give you startup/shutdown features tooo.

    thanks for the replies.

    The computer has been playing 1 hours worth of songs straight now, and running great. In my truck, it wouldn't stay on for more then 5 minutes without locking up. So I think you're definitly right in saying that it's power related.

    What I'm going to do next as a quick test, is put the computer back in my truck, and run it, but plug the computer powersupply into an extension cord and see what the results are. I'm thinking that if it locks up...there has to be some kind of wiring problem somewhere.

    If it doesn't lock up...then the only thing left is, like you said, the inverter. I think at that point, I would really have to decide as to whether to buy an inverter or upgrade the system...But i'm definitly going to take your advice if I do upgrade the system and probably go with a laptop.

    One of the reasons I went with the p4 2.8 powerhungry monster is because it was given to me for free

    yeah, there are larger dc/dc solutions out there, I know an opus 150 won't handle that reliably, but a little bigger might...
