I will be getting a 500BG WD Portable Hard Drive that I would like to use for a time machine back-up. My questions is, would I also be able to put other files on it (video files), or does that drive have to be specifically for the Time Machine back-up? The HD in my Macbook Pro is only 160GB so I wanted to keep my video files on the same external HD so they don't take up all my space. Is that possible? Also, I haven't played with it yet, but Time Machine would only back-up when I connected the drive, yes? If that's the case, then how would I put my video files on the HD if the computer just thought that I wanted to create a back-up every time I connected the drive? And finally... is there any way to connect this HD to my Verizon FIOS router (there's a USB port on the back) so that I can enable wireless backup? That would rock! I'm not all that great with this networking stuff, but I do know my way around computers. Thanks!
