Hard drive is Disk 0 CHANGES to hard drive is Disk 1??? And still works!!!

    Running Windows XP Pro 64-bit edition. I notice that my primary hard drive
    is Disk 0. If I add another hard disk to the system, the primary hard drive
    becomes Disk 1! And still works!!! I thought the hard and fast rule was
    that disk 0 ALWAYS stays disk 0 REGARDLESS of whether or not an additional
    hard drive gets installed. The additional drive in my case is a removable
    drive which sits inside a drive bay which replaces the CD-ROM. Am I missing
    something?

  2. Well, you are probably right - AND you are probably missing something? If
    your original HD (0) is a SATA drive, which would be reasonable to assume,
    when you add a drive that is IDE/ATA the BIOS enumerates this one before the
    SATA drive. Since SATA is an extensiion of ATA it looks up all IDE
    connections first as it used to and any SATA drives are relegated to second
    place in this regard. The BIOS is smart enough to keep CD drives separate
    and you may somewhere have a setting where you can configure the added HD
    separate from the internal one(s), or different connectors to attach your
    cables. You should read your Motherboard Manual carefully, if you end up
    adding an internal HD later you could have havoc play with your boot order.

    Great answer! The primary drive is SATA and the secondary drive is ATA.
    Your explanation rhymes reasonably!

    Thx for your feedback. I will take this knowledge and build upon it.

    Anyway I can tell the system, to enumerate IDE AFTER SATA (instead of the
    default which is IDE first)?

    Unless such an option exists in BIOS (which seems highly unlikely), I doubt
    it.

  7. Like Bill says - any such option will have to sit in the BIOS, but I do not
    think it must be 'Highly Unlikely' - I have more than one machine of
    different brands running that does this, but it is highly likely that you
    should have to be on good friednly terms with your BIOS - you may have an
    option to flash to a newer version, or simply do it the hard way and
    close-read every single word that appears in every single page inside the
    BIOS Setup.

    You may have an IDE sub-section under the Advanced section, if you enter
    this you can see the devices that the machine is currently aware of, and you
    can usually arrange them with the '+' / '-' keys. Your controlling keys may
    vary according to the language of the keyboard - whatever you have will fit
    the english keyboard but the manufacturer usually made provisions for this
    so it boots in a keyboard/language transparant way, you may have to
    experiment there. It's usually not a problem.

    Do Not Make Changes That You Don't Understand!
    -----------------------------------------------------

    For a good starting-point, I would go ahead and turn OFF every single
    setting in the BIOS that you KNOW that you are not going to need, things
    that support devices that are not installed, it's a great exercise and it
    will shorten the time it takes the machine to Boot and it may become more
    stable or robust.

    If you don't have your Motherboard Manual, get it! Most manufacturer's have
    it for download in the BIOS and Driver Support section. When You have it,
    read it and get familiar with it, your digital buddy will thank you for it!

    If it's a Notebook, you may have 'close-to-nothing' that can be changed in
    the BIOS, then you are out of luck, but you may have an option to attach
    and/or remove devices before installing the OS, it will usually remember the
    state it was in when the OS was originally installed! (Vista has changed
    this a bit. . .)

    Log on to the site that has drivers and BIOS updates for download of your
    system - it should have some kind of Forum, register yourself and if it's
    any good, get to be a regular and you'll probably have a selection of
    knowledgeable people helping you out with any issues that are directed
    towards YOUR specific issues.

    Good Luck!

    I stand corrected by assuming this meant some generic checkbox option for
    IDE after SATA, instead of thinking of that ordered list in BIOS!! (well,
    duh to me). :)
