I recently bought a Maxtor 200GB drive and put it in an external enclosure. I'm using it right now, and have formatted it to the MS-DOS Filesystem (I'm assuming that's FAT32). I have been using it for about a week with no issues, but now that I think about it, since it is a FAT32 drive, won't it have to be defragged every so often? Would I be better of formatting it as a Mac OS Extended (Journaled) drive? If I format it differently, which type of file system would you guys say is the best for an external drive?
