This command transfers the number of blocks of data specified in the "Transfer block count" field from the INIT and writes them in continuous logical data blocks with the logical data block on the disk media specified in the "Logical block address" field in the CDB as the top.

The functions of this command are the same as those of the Group 0 WRITE command (Section 4.2.3) with the exception that it is possible to specify 4-byte logical block addresses and 2-byte transfer block counts. However, when zero is specified for the "Transfer block count," the command is terminated normally without pre-fetch being performed.

In this device, specifications to the "FUA" bit in CDB byte 1 are invalid and operation is as if zero is specified.

The specification of bit 4 of CDB byte 1 is invalid and the specified value is disregarded.
