    USB Drive + Component Cable Issues

    Has anyone else come across this issue ?

    I tried the component cable along with a usb hard disk plugged into the wii and the picture was horrible. It kept going on and off and had a whole load of noise on the screen.

    Disappears as soon as you unplug the hdd.

    Works fine with the normal AV cable...

    Any known fixes ?

    Thanks

    Hi Madshark,
    Sounds like inadequate shielding in your cable.

    tried with a few other cables same result...even when the device is not actually powered on (my ext hdd runs on power from the mains maybe thats the cause of the issue) the noise is still present. It goes away only if i actually remove the usb cable from the port.

    Hmm...guess it's not shielding or excessive power demand. Does it happen with both usb ports? It sounds like your usb connection itself is at fault. Check physical positioning of the ports/pins etc maybe. Don't know if opening the Wii to check the usb port connection and wiring is an option or even helpful, but it sounds like the usb port, internal pins, or associated internal wiring must be the problem. Let you know if I think of anything else.

    im pretty sure nothings wrong with the usb ports. Infact im 98% sure it is a powerline interference. When i plug the wii and the hdd into the same extension the issue is much worse. Im going to try a self powered drive and see if its still persistant. Will post back.

    Maybe your HDD is emiting some type of RF energy, I have seen others with this problem when useing a HDD enclosure. Check your USB cable, see if it is shielded (USB cable will have a round piece of plastic clamped around the wire), or if you haven't then try moving your HDD away from your component cables or even try a different source for your power, or, it sound like a lot of work but try grounding the HDD if not everything including your TV. All electrical applicances should be grounded anyways.



    Here is a quote from the Wii setup manual :

    Operation is subject to the following two conditions:
    (1) this device may not cause harmful interference
    (2) this device must accept any interference received, including interference that may cause undesired operation

    OK, good luck. I didn't think it was power line because you said problem occurred with device powered off. But if you have another drive you can try-that self-powered one. That should help at least in providing more clues or a fix (we hope). Good Luck and let us know.

    I have the same problem. the USB HD adds component interference. I think it is some weird combination of the USB port and the HD spinning. the HD can spin by itself and there is no interference, until the the USB cable is plugged in. If the disk spins down the interference is less, but still evident and goes away completely if the USB cable has been unplugged.

    I had assumed I must have a dodgy external USB drive with a flaky USB port ... now I see you too have the same problem I am thinking it may be something wii related. Have you made any progress with your investigation?

    Your situation sounds more like an unshielded USB cable and EMF leakage from the USB HDD enclosure.
