    Fairly new Intel Mac Pro (6 months old)

    I installed my WD MyBook (Firewire 400 connection) the day I got the computer, and it's been running fine ever since.

    Last night I rebooted and it seems to be gone. It's not mounted on the desktop, and it doesn't appear in Disc Utility.

    Any idea where to start to troubleshoot? Thanks.

    1) Verify that power is connected and HD is on.

    2) Double check the FW connection.

    3) Try another FW port on the Mac Pro (then another on the HD if it has one).

    Also, is the drive making any sounds (either usual or unsual)?

    try rebooting with it not plugged in, then try plugging it in.

    If that doesn't work try the USB port (it has one right?).

    If that doesn't work, I don't know, I do a repair permissions, then a reset p-ram and it fixes alot.

    edit: thought of something else, I've had a firewire cable just go mysteriously go bad. It was a very confusing problem cause you'd assume your cable works. This might be helpful, I don't know.
