Depending on the partition scheme, these are the file systems Mac OS 10.4 supports: This supports all the Mac-specific functions such as aliases and resource/data forks. In most cases, you'll want to use Mac OS Extended (Journaled) as the "volume format" (file system). You can put partitions with any of the supported file systems on a GUID disk, but only Macs running Mac OS 10.4 can access these disks.

However, you can't put any FAT (MS-DOS/Windows-compatible) partitions on the disk. If you want to boot a PowerPC Mac from the disk, you need to use this partition scheme.

If your needs are more complex, select the "partition" tab. If you want to keep things simple, just select a disk, click on the "erase" tab and you can create a volume that uses the entire disk with a few mouse clicks. After you start it, Disk Utility shows a list of all available disks along with all the volumes (partitions) present on those disks on the left side of the window. The easiest way to do that is with the Disk Utility in Applications/Utilities.
