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.

OTOH, with the regular ATA stuff I've experienced loads of IRQ problems, crashes and hangups. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
