    if the disks are dying ... and are still under warranty ..
            - the disks are probably running too hot
            - the disks are probably a bad batch from the manufacturer
            - somebody dropped the box of disks during shipping one time
            too many

            - i say, disks do NOT die ... fans die 5x - 10x more often

    one should be able to fake an ide disk to look like a hot swap
    ide disk ... but nobody makes that connector... and i keep wondering
    why not .... it's simple ... all disks have a "ready" signal
            - missing/dead disks means "drive not ready" which
            should force the ide device driver to try again

    i think firewire had its day and its dying ... usb is taking over
