    DVD Rom IDE to USB, 25ft. would it work?

    I have a slim slot loader drive. I have the adapter to take it to IDE.

    I did a little sloppy planning, and don't know how I'm going to connect the DVD drive in my dash to the car pc in the trunk.

    this is my train of thought:
    get an IDE to USB adapter, and run a 25ft cable from the trunk to the dash.

    do all of these adapters require an external AC adapter for power?

    A couple of problems arise in my mind. Will DVD video play without hiccuping over USB? USB is a _LOT_ slower then the IDE interface. but at 480mb/s I think it should be OK.

    Next problem I see is distance. Right now I run a 25ft USB cable from hub connected to my printers on one side of the room, to a computer on the opposite side. though this is just for printing, i haven't come across a problem with it.

    So let me know if any of you guys have any recomendations or anything!
    thanks for any help or info
    -Matt

    The IDE to USB adapters usually use The USB port for power. The drive may require a second usb port to power it. Most slim drive adapters use a floppy drive power connector. If that is the case then extend one of those to the front as well. 25ft may cause a problem with your maximum transfer rates. Hard to say until you try it. If it's too long for it you could put a USB hub in the middle. It will buffer/boost the signal better for long runs.

    I am sure you can cut down on the 25ft unless you are driving a school bus. 25ft is f**king rediculous.

    I think USB is rated to only ~15ft without a repeater or hub.

    Might work on longer cables, but the specs say about 15 ft. Just try.. Otherwise, use a hub, e.g. under the drivers seat, gives you additional USB ports for other equipment as well, and solves the problem with the cable length.

    You expect the harddrive to get the juice from the USB connection? Are they even rated for that?

    USB stop functioning after 16 feet. I tested it numerous times with differnt devices.

    And trust me, you wont need more than 16 feet unlesss your zig zaging it along the width of your car a few times...lol.


    I thought i would have prolems too. I got a mazda 3 hatchback. hatchback=wagon. I thought for sure i would need like 15 feet to run from my monitor to the pc in my trunk.. Wrong. All i needed was 6 feet of extra usb cable. And even with that I got some cable to spare.

    I have three of those USB-IDE adaptors. They all don't need power, they get it from the USB port. There IS a powersupply included, but thats for powering the actual drives only (5/12V molex). I've replaced this powersupply with a homebuild powersupply. Offcourse you can also use a regular powerpc when using a ITX mainboard as well.

    eg: http://cgi.ebay.com/ws/eBayISAPI.dll...741123533&rd=1

    Prince: $25.. I got them also from Ebay, payed 14 eur for it. (all prices including shipping)

    As you can see on the picture: The USB-IDE adaptor itself doesnt need power, power is only for the drive.
