ok so i hooked this thing upd to my macbook ran the installation now my question is is there anything I still need to do before i can start using this hdd? I still have the software that came on it do I just create a new folder and go use it? Another thing when installing it asked weather i wanted Mac, or mac and pc compatible. I choose mac and pc but apparently that option doesn't allow time machine to work how to i get time machine to work on this. And one last this when i click eject on my mac the drive shuts off, but as soon i i pull the usb cord out it turns back on should i pull the power cord after i eject?
