      <title lang="en">Manage volumes and partitions</title>

      <para lang="en">
         The word <emphasis>volume</emphasis> is used to describe a storage device, like a hard disk. It can also refer to a <em lang="en">part</em> of the storage on that device, because you can split the storage up into chunks. The computer makes this storage accessible via your file system in a process referred to as <emphasis>mounting</emphasis> . Mounted volumes may be hard drives, USB drives, DVD-RWs, SD cards, and other media. If a volume is currently mounted, you can read (and possibly write) files on it.
      </para>

      <para lang="en">
         Often, a mounted volume is called a <emphasis>partition</emphasis>, though they are not necessarily the same thing. A “partition” refers to a <em lang="en">physical</em> area of storage on a single disk drive. Once a partition has been mounted, it can be referred to as a volume because you can access the files on it. You can think of volumes as the labeled, accessible “storefronts” to the functional “back rooms” of partitions and drives.

      <para lang="en">
         Your computer most likely has at least one <emphasis>primary</emphasis> partition and a single <emphasis>swap</emphasis> partition. The swap partition is used by the operating system for memory management, and is rarely mounted. The primary partition contains your operating system, applications, settings, and personal files. These files can also be distributed among multiple partitions for security or convenience.
      </para>

      <para lang="en">
         One primary partition must contain information that your computer uses to start up, or <emphasis>boot</emphasis>. For this reason it is sometimes called a boot partition, or boot volume. To determine if a volume is bootable, look at its <guimenu>Partition Flags</guimenu> in the disk utility. External media such as USB drives and CDs may also contain a bootable volume.
