I'm pretty sure that most drives out there will immediately attempt to safely retract or park the heads the instant that a power loss is detected. There's too much potential damage that can occur if the heads aren't able to safely retract to a landing zone or ramp, that trying to save "one more block of cached data" just isn't worth the risk. --eric - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
