    Im new to system administration with windows 2003. Im having problems with
    trying to set up a hot swap drive. I have the hot swap bay, hard drive, and
    Sata cables all connected. Windows recognizes the disc (in disk management)
    and I have formatted it with NTFS. If the drive is hot swappable, isnt it
    supposed to show up as a removable device? I know that you just cant just
    remove the disc, and that there is a process for removing discs. Also, should
    this be a dynamic disc or a basic disc so that it is hotswappable?

  2. You have a raid controller I suppose.
    Have you already contact your vendor before to post there? I thought your
    controller would manage the hot swap.

  3. The answer is no because most serial ATA controllers emulate the old ATA
    controller which is not hot swappable. Even raid controllers will not show
    the disk as removable. I think you are being confused with the terms
    Hot swap means the drive/device can be removed while the system is running
    and is generally used for maintenance or device failures
    while Removable is operating system aware.
    If you want a removable hard disk then use a USB hard disk.

    I think I was setup for failure with this one. The server that I was assigned
    to install the swappable devices in has a desktop board installed in it (no
    one knows why). I had a conversation with Intel about this board and they
    said that they do not support swappable drives with this board in a Windows
    2003 environment. That being said, were going to order a server board that
    supports hot swapping.

    That being said, What is the process for removing a drive, and then
    inserting a different one? How do you get around the fact that each drive has
    a drive letter assigned? Do you have two (or more discs) that are set up with
    the same drive letter, and then pull one out and put a different one in? If
    that is so, how does windows detect the change? Thanks for your help!

  5. I think Intel may have not explained the exact use of hot swap on their
    server boards. Some Intel server boards have a built in Sata or SCSI Raid
    Controller which come with software that allow you to break the RAID or
    Mirror then remove the drive. A RAID or Mirror will generally show as 1
    Physical drive even though it has more than one hard disk connected to it so
    you can remove 1 of the drives in the RAID and it will keep working in a non
    redundant state.
    This is not the same as a removable disk.
    Removable disks are allocated a drive letter which you can change in disk
    manager and when the drive is removed the Drive letter is released to be used
    by the next Removable disk.

  6. No, it is not supposed to show up as removable. Windows (nor the
    mainboard BIOS) knows it is hot-swappable. It is just another hard
    drive as far as they are concerned.

    It does not have to be made dynamic but should have a Windows ID which
    is probably already done if you have formatted it. There is a lot of
    info on dynamic disks in Windows help. Don't make a disk dynamic
    unless you have good reason to.

    I assume you have a RAID system. If so, read up on the RAID docs or
    contact the manufacturer for more info on hot-swapping drives.
