    I'm not quite clear on what you mean.
    The voltage ON the HDD circuit board is out of an expected
    value or the connector pins read incorrect?

    If connector pins are off, unplug the drive and take another
    reading. I would've expected that if drive were pulling
    down the supply too much, it "should've" shut the supply
    down. Then again I don't recall the specifics of the supply
    you're currently using.

    Are you still using that adaptable supply? If so, are you
    sure it's of high enough current rating? Most of the ones
    I"ve seen are 500mA, 1A at most which could be insufficient
    to spin up a drive, or in other words if it's non-regulated
    it might be pulling voltage down so low the logic is
    non-functional and needs then reset... but not by unplugging
    and replugging since the whole cycle repeats.

    That is a good idea, probably the first thing I would've

    My 80g Western Digital external HD just failed, the same conditions as
    Jay's. Red/green lights flash, hd not spinning. I was swapping hd's
    around and I could have plugged the WD hd into my laptop power supply.
    WD 12Vdc 2A, laptop power supply 19Vdc 3.16A.

    Anyway, removed hd from enclosure and installed in 2 different machines
    as slave. The machines would not boot. They stopped at master hd
    recognition. The master was not identified and I received a boot disk
    failure message. With WD hd removed the machines boot fine.

    I am pretty sure the circuit board is fried. I have not removed it
    from the hd to inspect the opposite side.

    Any suggestions.

    well, as I hear, its not easy to swap a WD drive as they have some
    kinda information embedded in the circuitry for every individual drive.
    It will indeed make data recovery tough.

    Actually it was claimed by a data recovery website from UK. So I dont
    wanna do that, so Ill not ruin my data recovery chances.

    Welcome to the club, just for the start, WD's got a voltage regulator
    and its got a fuse as well. So its not possible to overload the circuit
    by anychance. Coz I tested them myself :)

    So in essence its the drive thats dead or you have fried your
