PS3 HDD on Xbox 360 (Not Trolling, Bashing, Flaming etc etc etc)

Ok mods...i am NOT trolling the PS3 or anything like that i actually like all 3 systems...i am simply asking a question that does not belong in system wars because...its not a question to fight over.

Is there any way you can attach the PS3's 60GB HDD to the HDD port on the 360 so i can changeit from 20GB to 60GB maybe with a wire, or plug it into the usb port or memory unit port.

Oh, you mean like using a standard Laptop HDD as an external HDD?

I've never seen that before

Specifically using the PS3 HDD(switching them back and forth) could be problematic.
