<br />
'''SGI volume image''' (correct terminology unknown) is a low-level disk format used with SGI/IRIX computers. It is used on hard disks and CD-ROMs, and associated image files.<br />
<br />
It can be thought of as a header, or as a container for one or more filesystems or other partitions. Often, it contains an [[EFS]] filesystem.<br />
<br />
(TODO: Do some CDs hybridize this format with [[ISO 9660]]?)<br />
