A drive is not, however, a CD, a Zip cartridge (remember those), or a floppy disk. • Volume: A volume is a logical storage device. Since a drive can have more than one volume, this term represents a part of a drive that appears, to the user, as a single unit.

A volume also contains a file system, which allows a computer to keep track of where files are stored. A drive may have a single volume, or it may contain several. • Partition: When you partition a drive, it contains multiple volumes. In many usages, volumes and partitions are the same, but not always. A drive can contain a single partition, or several.
