Virtual Partition

A partition of a logical volume identified in a logical volume descriptor by a Type 2 partition map recorded. The virtual partition map contains a partition number that is the same as the partition number in a Type 1 partition map in the same logical volume descriptor. Each logical block in the virtual partition is recorded using the space of a logical block of that corresponding non-virtual partition. A VAT lists the logical blocks of the non-virtual partition, which have been used to record the logical blocks of its corresponding virtual partition.
