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.
If you want to create partition to install other operating system on Mac system then sure you can do so. You will need to use Disk utility for creating partition mac. For secure creation of partition without disturbing the previous one OS, you will need to use third party software. http://www.partitionmac.com
