I want to setup the best external hard drive system with my new laptop and my desktop. I currently have a new mbp, and a pc desktop (vista). I use the laptop for audio recording and photoshop and I host some websites using dreamweaver. My wife uses the PC for a photography business, and for writing papers. How should I setup an external hard drive for this situation? Do I format ½ the hard drive for the mac, and ½ for the pc? Then hook it up to the PC and hope to access it over the network for my mbp? I would primarily use the hard drive for a backup on my mbp, while my wife would store photos onto the hard drive. Is it easy to setup this kind of network? I tried to setup a simple network to share printers which has got real buggy on me, so I need it to be somewhat simple. Last question: Can I assign the hard drive an IP address for easy access from the laptop? Any ideas appreciated. Thanks!
