so i just bought a WD passport external hard drive to use with time machine, its a 250GB which matches the HDD on my macbook. so the main purpose is to use time machine and back up all my files my questions are: - if i have everything backed up via time machine can i take my drive with me and see my files on a different computer? for example i just want to see a picture on a friends computer or something. - What do i have to do when i first connect the hard drive? the manual says its formatted to FAT32 (i'm at work and havent gotten home to test it out) do i have to run disk utility to erase and reformat it? will my mac pick up the drive right away? - and finally alot of my friends still have windows, if i am able to see my files on another computer can it be a PC?
