I'd like to get a USB 2/FW 400 external hard drive to use with two macs running the most current version of OS X and a computer running Windows XP SP 2. Is it possible to do that? If so, can anyone suggest something around $200 USD that has a capacity of 160+ GB? And in a perfect world, it would be a fanless drive. In fact, I really like the look of Fantom Drives and the fact that they are fanless, but I didn't see any that were both USB 2/FW 400 capable. Thanks for any advice you have to offer!
