    I have been using a Buslink 1394 Firewire HD model #FW80 72E on 2
    4-STABLE systems for backup. The Firewire ports are onbord on an
    ASUS P4PE and an ASUS P3B-1394 motherboard.

    Pulled this from pricewatch, I have not used this vendor before or
    the included Firewire card, my Buslink 1394 drive came w/o:

     Generic (Hard Disk Drives) Buslink 1394 Firewire 40.0GB
     7200rpm External Hard Drive W/Firewire Card
     Part - HD-BL40FW2
     Price - $ 138
     Shipping - $6.00 - 8.00 Fed Ex Ground Insured

    My firewire chassie appears to be easily opened, and if cost is
    that important you could try swapping drives in the chassie after
    removal. (warranty issues beware)

    --------------
    the correct sequence for hot swapping this firewire hard drive on
    my motherboard is this:
    (this is with firewire and sbp devices compiled into my kernel)

    ...
    plug the firewire drive cable in
    run 'fwcontrol -r'
    mount the firewire drive
    do backups
    unmount the firewire drive
    unplug the firewire drive cable
    ...

    My PC and firewire drive would work fine on the first time plugin
    of the hard drive, but unplugging the drive and coming back later
    to plug in again needed the 'fwcontrol -r' to work properly. YMMV

    This reconnect issue may be fixed now in 4-STABLE for my firewire
    on-board interface :-)
    ---------------

    Another option to research would be the new SATA IDE drives and
    controllers and trays. Anyone with more info regarding doing this
    on 5.x or 4.x please chime in!
