Command Specifications

If this command is terminated with a CHECK CONDITION status, the additional sense code/additional sense code qualifier in the sense data is other than "No defect spare location available [=32- 00], and a valid logical block address (other than X 'FFFFFFFF') is displayed in the "Command inherent information" field, it is necessary for the INIT to reissue this command by the following procedure after executing recovery processing (shown in Section 5.2) in accordance with the contents of the sense data.

1.Delete the defect descriptors which precede the defect descriptor that specifies the logical block address displayed in the "Command inherent information" field of the sense data from the defect descriptor list specified in this command, and leave that defect descriptor in the list.

				information” field of the sense data.

Figure 4.2 Correction of the defect descriptor

2.Change the "Defect List Length" in the header and add the new "Defect descriptor list" corrected in 1), then reissue the REASSIGN BLOCKS command.
