    Hey Folks,

    Installing a FDD Cable is not rocket science is it? I didn't

    think it was!

    I received all of my Vantek Yellow Round IDE Cables from

    NewEgg and I installed them all. The first time I booted up

    my FDD activity light stayed on constantly so I assumed that

    I may not have had the cable seated properly in the MoBo or

    the Drive.

    So I opened the case back up and removed the cable and then

    plugged it back in making sure everything was seated properly.

    Well the activity light is off but I get no drive activity

    at all when I try to read a disk. (the power is plugged in)

    My MoBo does not support dual FDD's and the Vantek FDD cable

    is a 24" with dual connectors. Could this be causing a communication

    error some how?

    Is there a way to verify which side of the connector is Pin 1 on the FDD cable, as well as the Pin 1 on the FD connector? Or look for tale-tell notches at the center of the connector on the FDD cable and how it mates to the FD itself. Do the same on each end. If nothing works, go back to the old FDD cables, if it works, then your new FDD cable is the culprit.

    Patrick,

    I am thinking the cable may be the culprit. There are notches

    at each FDD connector that only permit it to insert into the

    receiveing terminal of the MoBo and respective drive one way

    only (pretty brain dead). The Vantek cables are extremly well

    crafted and I find it hard to beleive that it is actualy

    defective per se. I am just wondering if the dual FDD connector

    is effecting communication since my MoBo only supports one

    FDD. There is a "twist" in FDD cables (for what reason?) if

    this cable has 2 of these "twists" perhaps that is the problem.

    Or perhaps the first time the drive wasn't recognized maybe

    my Bios disabled that channel. I will need to pop into my

    Bios and take a quick peek just to eliminate that possibility

    as well.

    The fact that the cable is a dual device cable has no bearing. You could, if you wanted, add a second floppy to that cable.

    The power light staying constantly on is usually a sign that the floppy power connector is on up-side-down. This is a common issue.

    I will check the cables again tonight.
    THe power connector can only go on one way but the FDD Cable
    is another story. It is possible that I have the cable backwards (meaning I have the MoBo Connector going into the
    FDD) but i seems highly unlikely because the way the cable
    is made you have a long section then 2 device connectors in
    close proximity. I assume the long section is the MoBo end
    and then the end with the 2 connectors close by is the device
    end (or logic would dictate that is the way) [​IMG]

    If the floppy light stays on its almost always due to the cable being on backwards on either the motherboard or on the drive. I gather the cable you have has a connector for the motherboard and two connectors for the floppy drive. If thats the case try the other connector on the cable. If you can rule these out I'd try another cable to make sure the drive isn't defective (even it worked a day or so ago)...if those don't fix it you likely have a bad cable.

    Your mobo will have a '1' at one end of the socket. Also, all floppy drives have a '1' near the first pin. You might have to yank it and use a strong light and a magnifying glass to see it, but it will be there.

    Also, as for the twist in the cable. The first floppy drive has to be the plug with the twist on it. You cannot use the plug for the 2nd floppy. It just will not work.

    As for the power, I have seen drives where it is possible to insert the power plug in upside down, so check that out too.

    Hope that helps.

    Well consider me still befuddled!
    I took the system apart numerous times tonight ( getting all
    my wires and cables neatly routed inside the case) and I
    unplugged the FDD Cable and looked over it real good and also
    checked to make sure I was plugging it in correctly. The cable
    does not have a #1 instead has arrow's designating the #1
    Pin. The MoBo Socket has a #1 and it was plugged in correctly.
    I tried my other FDD and I get the same thing.. Green light
    on.. My only conclusion would be that the cable has to be
    bad.... Seems like Larry Seeno has a point about getting
    lots of bad stuff from NewEgg... but we won't go there [​IMG]
    I am not about to spend 2 or 3 dollars to return a 8 dollar
    cable.. No farking way. I need to try my original cable again
    just to be 100% positive that the cable is the cause but to
    be honest, it couldn't be anything else!

    Hmm... IDE cables and Floppy cables aren't identical, are they? I mean, are you trying to use a normal IDE cable for the floppy?

    For future reference if you have an older floppy drive you CAN put the power on upside down. I have done this.

    If your light stays on, the cable is put on there incorrectly, but if when you boot the drive starts to spin up, and up, and up, and you think its going to explode, then your power may be on incorrectly. It takes a lot of work to do this and that may not happen on all drives but it did happen to one of mine once.

    I only have old floppy drives so I don't know how the new ones look but the ones I have just have pins stickign out the back, not an actual plastic case around the pins. What i'm saying is, it is possible to be 1 pin off and thus on the side of the connector 2 pins would be sticking out.

    Just make sure it is on there correctly and then start to eliminiate the culprit based on some tests.

    Run w/ the old cable, if it no work, you know its not the cable, try another drive, if that don't work, you know its not the drive (at this point we'd point to the controller, very unlikely however) lastly if you can try both in another computer, this will positively identify if its the controller in your new machine, or something else.

    Let us know,

    Jon

    My power cable will not go on upside down, there is a metal
    bar above the pins that hits the locking tab on the power
    supply connector that does not allow it to interface upside
    down. The power connector is on correctly.
    I am using a FDD cable not a regular IDE cable.
    The cables are connected correctly. I have tried both drives
    both do the same thing.
    I have not yet tried the original cable (that worked) I will
    have to try it again. If that does not work then somehow I
    screwed up something on the MoBo would be my only guess.
    I touched the back of the MoBo while I was inserting the
    cable (so the MoBo wouldn't flex) I don't beleive that I
    had any sort of static discharge because I grounded myself
    previously.

    Okay it's official I am an IDIOT!
    I had the FDD Cable in backwards at the FDD! But but but!
    It's not entirely my fault! Aparently the worker who assembled
    the cable felt that the connectors went on better backwards!
    I am used to the cable exiting the connector at a 90 degree
    angle facing down. This cable has to be backwards because
    it faces up, not only that but even if I did hook up my
    second FDD I couldn't because the other cable faces away
    from the drive because the cable is Bass Ackwards!

    Like we said drive lights that come on and stay on are almost always due the the cable being backwards[​IMG] Glad you got it sorted out!
