Partitioning a disk
Partitioning a hard disk divides it into sections called “volumes.” Each volume appears as a separate hard disk. In the Partition pane, you can choose how to partition a disk, change a volume’s size, and change the number of volumes on a disk.

Enlarging a volume
You may be able to increase a volume’s size without erasing its data by erasing another volume and combining them.

Creating new volumes
You may be able to create new volumes on a disk without erasing any of its data by creating new volumes from the unused space in the existing volumes.

Reusing a hard disk
If you want to reuse a hard disk, you can partition it, which erases all of its data and creates new volumes. To partition a startup disk, you must first restart your computer from another disk, such as your Mac OS X Install disc.
