Well, why use Fat32? I already know that it is inferior in many (all?) ways than the NTFS format... but I'm planning to get a Mac soon, so I'll need to use the Fat32 format. So basically, I'll use Boot Camp to make two partitions, one for Mac, and one for XP... and then get another partitioning program to make a Fat32 partition for my personal files that I want to be accessible to both OS's. Now I want to know how much worse Fat32 is in comparison to NTFS. Please include issues of speed, stability, and security in your posts. Thank you.
