Hi. I have an old laptop laying around. I'm considering installing windows server on it. Then I'm gonna connect it to my router. Then I'm gonna attach my Western Digital My Book Studio Editin II 2 TB to the laptop via Firewire 800. If I format that external harddisk to Mac Journaled file format before connecting it windows server pc, will I be able to set my Time Machine in my Macbook Pro to back up my stuff to Western Digital over wireless home network?
