SCSI Multimedia Commands (MMC) is a standard defining a SCSI/ATAPI based command set for accessing and controlling optical disc readers/writers (any device of type 05h). Thus, optical drives for the compact disc , DVD , and Blu-ray disc fall under this specification.
On a parallel SCSI bus, a device (e.g. host adapter, disk drive) is identified by a "SCSI ID", which is a number in the range 0–7 on a narrow bus and in the range 0–15 on a wide bus. On earlier models a physical jumper or switch controls the SCSI ID of the initiator ( host adapter ).
SCSI Pass Through Direct (SPTD) is a proprietary device driver and application programming interface (API) that provides a method of access to SCSI storage devices. Originally developed in 2004 by Duplex Secure Ltd., it is now owned and maintained by Disc Soft Ltd., [ 1 ] the developer of Daemon Tools .
Some opcodes produce different, though usually comparable, effects in different device types; for example, opcode 0x01 recalibrates a disk drive by seeking back to physical sector zero, but rewinds the medium in a tape drive. SCSI command lengths. Originally the most significant 3 bits of a SCSI opcode specified the length of the CDB.
The interfaces are IOCTL_SCSI_PASS_THROUGH and IOCTL_SCSI_PASS_THROUGH_DIRECT. Applications can build a pass-through request and send it to the device by using this IOCTL. SPTI is accessible to Windows software using the DeviceIoControl Windows API. [2] ImgBurn offers SPTI as a method for accessing optical disc drives. [3]
USB Attached SCSI (UAS) or USB Attached SCSI Protocol (UASP) is a computer protocol used to move data to and from USB storage devices such as hard drives (HDDs), solid-state drives (SSDs), and thumb drives. UAS depends on the USB protocol, and uses the standard SCSI command set.
The ASPI manager software provides an interface between ASPI modules (device drivers or applications with direct SCSI support), a SCSI host adapter, and SCSI devices connected to the host adapter. The ASPI manager is specific to the host adapter and operating system ; its primary role is to abstract the host adapter specifics and provide a ...
The SCSI commands and responses used by each class of ATAPI device (CD-ROM, tape, etc.) are described in other documents or specifications specific to those device classes and are not within ATA/ATAPI or the T13 committee's purview. One commonly used set is defined in the MMC SCSI command set.
