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'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.
