    IDE hotswap has never worked (OOTB at least) in Linux, and based on my
    experience it never will. Seems the IDE folks doesn't care a bit
    about it. (No offence meant. Just keeping it real.)

    So if you really need this, here's the opportunity to make a whole lot
    of people happy by implementing it yourself. You'll probably need a
    lot of time on your hands - there's a very real chance that the IDE
    maintainers are too busy or whatever to answer any newbie questions
    you might have about how to attack the IDE layer.

    I disagree...
    I've used it for TBs of data without any problems.

    OTOH, with the regular ATA stuff I've experienced loads of IRQ
    problems, crashes and hangups.
