Hello, I juz bought a new WD My Book Essential 3TB and I want to know if I want to partition and reformat it, what are the best recommendations for formatting. One partition for Mac OSX Journaled and the other two as MSDOS(FAT), or two partitions for Extended Journaled and FAT32 for storage for my MacBook Pro with 320GB internal HD space. I also wanna use it for Time Machine Backups as well as storage as well... Thanks.
