you can try to try those clicking drives on another computer. if it still clicks then its probably the hard drives problem. if not, then something to do with your pc.
I think its a power management thing.
And no i dont know how it windows 7 does it.
Hard disk disappearing? answer/question it's ACPI.
im thinking that the firmware in the hard drive detects the spin down and parks the hard drive when the platters are spinning.
i may not be of much help but i tried =(.
