- * \brief SCSI Block Commands
- *
- * This file contains definitions of some of the commands found in the
- * SCSI SBC-2 standard.
- *
- * Note that the SBC specification depends on several commands defined
- * by the SCSI Primary Commands (SPC) standard. Each version of the SBC
- * standard is meant to be used in conjunction with a specific version
- * of the SPC standard, as follows:
- * - SBC depends on SPC
- * - SBC-2 depends on SPC-3
- * - SBC-3 depends on SPC-4
