The Format Unit parameter list shall be transferred from the Host to the drive. The data sent to the drive
consists of a Format List Header, followed by one Format descriptor, so the parameter list length is
always 12 bytes. When the Format Options Valid (FOV) bit in the Format List Header is set to one, the
DPRY, DCRT, STPF, IP, Try-out, and VS shall be set to zero. In this case, the format operation is
performed with an Immed function specified by the Immed bit. When the FOV bit is set to zero, the DPRY,
DCRT, STPF, IP, Try-out, Immed, and VS shall be set to zero. In this case, the format operation is
performed with the drive’s internal default setting. The default setting of Immed function is one. Even if
the format operation is requested with the FOV bit set to one, the drive’s default setting itself will not be
changed.
4.3.1 Format Code = 001b
4.3.1.1 Format Type = 00h (Full Format)
Formatting for the entire media is specified. The Number of Blocks field specifies the number of
addressable blocks for the entire disc and the Type Dependent Parameter field specifies the Block Length.
If the Immed function is set to zero, the drive will return the status after the format operation has
completed. If the Immed bit 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.
The READ DISC INFORMATION Command, the READ TRACK/RZONE INFORMATION Command and the
TEST UNIT READY Command is used to detect completion of the format operation. While format operation
is performed by the FORMAT UNIT Command that the Immed function is set to one, the drive terminates
these commands with the Check Condition status, LOGICAL UNIT NOT READY, FORMAT IN PROGRESS
(2/04/04). If the drive returns Good status for these command, format operation has completed.
