    You mean reprogram the firmware. Don't think wdc have new ones, so you
    are SOL.
    Get the full model number written on your drive (it's not just WD800)
    and have a look on

    PM2 is a power management jumper.

    I've been stumped about a method to clear the BIOS on
    my HDD to the correct setting.
    I don't know how it happened, but somehow my WD800
    drive tries to boot, and clatters, then ID's as a WD600
    and of course that stops the bootup.
    I switched the HDD into another system, and the mis-ID
    remains the same. Something has gone awry in the BIOS.
    Looking at the jumper bus, I noticed a mysterious jumper
    near the slave/master pins, called PM2. I'm wondering if
    this is a programming mode, and maybe someone knows
    if there is a program that initializes this drive as well.

    In have nothing to lose at this point.
    I'd appreciate some ideas.

  3. The disk is shot.

    I've seen this on other disks when they go really bad. The WD600 and
    WD800 most likely have the same controller and it gets the type from
    the media. When it can't read the media, it falls back to the default
    in the firmware, which appears to be WD600 in your case.

    The clatter you hear is the seeks it tries to get at the data.

    The data recovery houses are VERY expensive. The last time the
    company sent a 60GB laptop drive to OnTrack, the price was close to
    $2000, plus $5 a platter formedia (CD/DVD) the recovered data was put

    For personal use, add a SATA controller card and a large drive to an
    old computer and use it for over-the-network backups.
