A Removable Medium Bit (RMB) of zero indicates that the medium is not removable. A RMB bit of one indicates
that the medium is removable. Streaming Tape Devices should always report "Removable".
The usage of non-zero code values in the ISO Version and ECMA Version fields are defined by the International
Organization for Standardization and the European Computer Manufacturers Association, respectively.
The ANSI Version field must contain a 02h to comply with this version of this Specification.
A Response Data Format value of 02h indicates that the data shall be in the format specified in this Specification.
Other Response Data Format values are reserved.
The Additional Length field shall specify the length in bytes of the parameters. If the allocation length of the CDB
is too small to transfer all of the parameters, the additional length shall not be adjusted to reflect the truncation.
ASCII data fields shall contain only graphic codes (i.e. code values 20h through 7Eh). Left-aligned fields shall
place any unused bytes at the end of the field (highest offset) and the unused bytes shall be filled with space
characters (20h). Right-aligned fields shall place any unused bytes at the start of the field (lowest offset) and the
unused bytes shall be filled with space characters (20h).
A relative addressing (RelAdr) bit of one indicates that the device supports the relative addressing mode for this
logical unit. If this bit is set to one, the linked command (Linked) bit shall also be set to one; since relative
addressing can only be used with linked commands. A RelAdr bit of zero indicates the device does not support
relative addressing for this logical unit.
A wide bus 32 (WBus32) bit of one indicates that the device supports 32-bit wide data transfers. A value of zero
indicates that the device does not support 32-bit wide data transfers.
A wide bus 16 (WBus16) bit of one indicates that the device supports 16-bit wide data transfers. A value of zero
indicates that the device does not support 16-bit wide data transfers.
A synchronous transfer (Sync) bit of one indicates that the device supports synchronous data transfer. A value of
zero indicates the device does not support synchronous data transfer.
The Vendor Identification field contains 8 bytes of ASCII data identifying the vendor of the product as "SONY".
The data shall be left-aligned within this field.
The Product Identification field contains 16 bytes of ASCII data verifying the product as "SDX-470V". The data
shall be left-aligned within this field.
