    2.5'' hard drive

    hi, sorry if this has been discussed before but couldnt see a thread, i recently bought a pioneer mp3 headunit with the usb function, bought a freecom 2.5'' hard drive from pcworld, connected it up, worked fine then on the way to work if was saying no audio but was fine after 10 mins and was picking up all the tracks, someone at work said it could possibly be the cold that stopped it working properly to start with. i was wanting to just keep the harddrive in the glove box all the time but looks like i will have to take it in the house every night.. well in the winter anyways, was wondering if there was any way possible of insulating the harddrive to keep the cold out??

    given enough time the HDD will drop the ambient temperature of the car. Unless you introduce a heat source. Which may drain you battery.
    There really isn't any kind of insulation that would keep it warm overnight (6-12 hours). Are you parking outside or in a garage?

    From personal experience my HDD will work in a car that has been left out overnight in 5 Degree Fahrenheit weather. If it is much cooler out it take 5-10 minutes for the car to warm up then it runs fine. What temperatures are you experiencing? Many cold weather mp3car'ers will use solid state hard drives for booting as an alternative

    if it is insulated that will also affect how long it takes to warm up.

    for example:
    If the hard drive is 85F when operating
    A)Uninsulated after 4 hours it drops to 5F and wont operate
    but since it is uninsulated it will warm up quickly so in 3 minutes its up to 32F and will function

    B)Insulated:
    It takes 12 hours to drop to 5F, but the insulation blocks the heat from your car getting to the Hard drive so it takes 15 minutes for the heat to get through the insulation to make the HDD work

    If you search through your car you may find 'hot spots', put the HD there
    I have one under the center console by the Airbag sensor and Accelerometer sensors
    Also my head unit gets very hot. Those spaces may heat up your HD quickly.

    Before exploring this much further I would determine that temperature is the cause of your problems. Put the HDD in your freezer and see if it will start after it has dropped in temp. Just run the cord through the gasket

    Or you could take it out in the winter like you said

    it would be a bad idea to just wrap the harddrive up in something say a towel or foam? etc? im guessing it may overheat when operating if i did that?? i'll probably just take it out the car in the winter.

    Yea, just take it in with you. Wrapping it in insulation would make it too hot when running.
    Failure is not an option....



    It's installed by default on every version of Windows.

    So glad I live in Florida...

    If you could make a quick docking solution, or somehow modify the 5.25" docks already available, it wouldn't be such an issue removing it constantly.

    This could be not related to temperature actually.

    How much music do you have on this HDD?

    What does it say before it starts working? Did you change it over to radio during those 10 minutes or did u just let it try to keep reading?

    im sure its the cold thats stopping it working, theres 11,500 songs on it roughly, on a cold mornin it just says no audio then 5 mins later if i unplug it and plug it back in it finds the music, usually just listin to a cd while it warms up.
