## Data Object Description

This data object type describes dimensions using the cylinder, head, sector (CHS) coordinate system. This coordinate system is generally needed for partitioning for legacy reasons. When defining partitions, many partitioning utilities do not function correctly when certain CHS constraints are not met.
