Hi all, I need some experienced help. I'm sure someone has done what I want to do. I ordered a 320 gig HD to replace the 120 in my MacBook. I'm running Parallels for some engineering software. One tool recommends running Windows natively for performance instead of Parallels. (They are coming out with a Mac OS X version soon !) I ran out of HD space and it basically killed my Parallels vm. So ... I figure I need a Windows partition so I can run BootCamp. Mostly I'll be running OS X. and Parallels as needed. And Bootcamp only when really necessary. I want to be able to read data from partition when in OS X. I'll be running XP with minimal needs. What size partition ? I'm guessing on 30 to 50 gig? Any recommendations? What format? I think I saw a recommendation for FAT32. What order to do things? Any help is greatly appreciated.
