public final class Read10Cdb
extends ReadCdb

This class represents Command Descriptor Blocks for the READ (10) SCSI command.

The READ (10) command requests that the device server to read the specified logical block(s) and transfer them to the data-in buffer.

Each logical block read includes user data and, if the medium is formatted with protection information enabled, protection information. Each logical block transferred includes user data and may include protection information, based on the RDPROTECT field and the medium format.
