R11 Series Drive Command Reference Manual Version 1.00
4.3.1.6 Format Type = 26h (+RW Basic Format)
The Number of Blocks field shall be set to either the value returned by the READ FORMAT CAPACITIES
command or 0xFFFFFFFF. In this drive, any other value will be accepted, but it is no effect on the format
operation.
The Type Dependent Parameter has the meaning of “New format” when it has the value 000000h.
The Type Dependent Parameter has the meaning of “Restart format” when it has the value 000001h.
If the field contains any other value, the drive will terminate the command with CHECK CONDITION
status and set SK/ASC/ASCQ values to ILLEGAL REQUEST/INVALID FIELD IN PARAMETER BLOCK.
If the Immed function is set to zero, then once the foreground format process has completed, the
command will be terminated with GOOD status. If the Immed function is set to one, the drive will return
the status as soon as the command descriptor block has been validated, and the entire Format Descriptor
has been transferred.
While foreground format process is performed by the FORMAT UNIT Command that the Immed function is
set to one, the drive terminates the READ DISC INFORMATION Command, the READ TRACK/RZONE
INFORMATION Command and the TEST UNIT READY Command with the Check Condition status, LOGICAL
UNIT NOT READY, FORMAT IN PROGRESS (2/04/04). When the background format process is started,
these commands will be terminated with GOOD status.
As for the REQUEST SENSE command, while the foreground format process is performed, the drive will
return a SK/ASC/ASCQ values set to NOT READY/LOGICAL UNIT NOT READY/FORMAT IN PROGRESS
(2/04/04), without the sense key specific bytes set for progress indication. While the background format
process is performed, the drive will return a SK/ASC/ASCQ values set to NO SENSE/FORMAT IN
PROGRESS (0/04/04), with the sense key specific bytes set for progress indication.
The SKSV will be set to one and the Progress Indication field will contain 16 bit unsigned value such that
(Progress Indication)/65 536 X 100% approximates the percentage of completion of the background
format process. Once the background format process is completed, the SKSV will be cleared to zero.
4.3.2 Format Code = 111b
This Format Code has a legacy definition for CD-RW. It is described in Annex E of the MMC-5.
The SESS and Grow bits are ignored by the drive.
The drive performs as same as the operation which the Format Code is set to 001b and the Format type is
set to 00h.
