Ok I bought a new LaCie 1TB External Hard Drive that works for both the windows and mac computer. I know that windows 7 saves files with different file formats than Mac OS X does. I am planning on getting windows 7 when it comes out and installing it with bootcamp on my MBP. When I install windows 7 will I have to partition the external hard drive as well as the internal hard drive? Or could I install windows 7 by itself on the external hard drive? Another question I had is if I install windows 7 on the internal hard drive will the external hard drive accept the file formats from both OS's at the same time? Or if you have another suggestion that would be great as well. I am just kind of looking for advice of how to do this. Thanks in advance.
