1) Should I ever de-frag my external hard drive? I de-frag my computer on a regular basis, but have never de-fragged the X-HD for fear of fucking something up and losing all my movies and music.
2) If and when I get a MacBook (

), will I be able to transfer music files from the X-HD to the MacBook, since the X-HD is formatted for FAT32 (or something like that)?
