Sense Key : 05 = ILLEGAL REQUEST
Sense Code/Sub-sense Code : 24-00 = Invalid field in CDB
“VALID” Bit : “1”
“ILI” bit : “1”
Information Field : (“Transfer byte length in the CDB) – (Original “Transfer byte length”)
Remark The calculation formula for the information field expresses 1 logical data block as n
physical sectors and n sub-sectors, and when negative, as a complement of 2.
Error recovery processing during execution of this command is performed in accordance with the
specifications in the MODE SELECT parameters (Page code 1: Read/Write Error Recovery
Parameter, Page Code 21: Additional Error Recovery Parameter, but the AWRE flag and DTE flag

This command requests that the device server write the single block of data transferred by the
application client to the medium multiple times to consecutive multiple logical blocks.
A "Logical Block data (LBdata)" bit of zero and a "Physical Block data (PBdata)" bit of zero
indicates that the single block of data transferred by the application client shall be used without
modification. A "LBdata" bit of one requests that the device server replace the first four bytes of the
data to be written to the current logical block with the logical block address of the block currently
being written.
A "PBdata" bit of one requests that the device server replace the first eight bytes of the data to be
written to the current physical sector with the physical address of the sector currently being written
using the physical sector format.
