This command allocates alternate data blocks for defective data blocks specified in the “Defect Data” list transferred form the INIT. See Chapter 3, “Product Specifications/Installation Procedures” in the Product Manual concerning alternate block processing methods implemented by this command.

The INIT specifies the logical block address of one or more defective data blocks in the “Defect Data” list which it transfers to the IDD. The IDD searches for unused spare sectors for use as alternate blocks and allocates these alternate blocks for the specified logical data blocks. Also, in the case of data blocks for which alternate data blocks have already been specified, the IDD allocates other usable spare sectors as alternate blocks for those data blocks.

Using this command, copying of the contents of the data in the logical data blocks specified in the “Defect data” list to the allocated alternate data blocks is attempted. If the data in logical data blocks which are specified in the “Defect data” list are correctable by ECC correction, the corrected data are copied and those data which are not correctable by ECC are copied as is in the uncorrected state (including the errors) and in the case of other media errors, X ‘00’ is copied in all bytes. Furthermore, the contents of data in data blocks other than the logical data blocks specified in the “Defect Data” list are not influenced by the alternate allocation processing through this command.

Note:

Copying of the contents of data in the logical data blocks specified in the “Defect data” list to alternate blocks allocated by this command is attempted, but in some cases, copying cannot be done. Confirmation of the contents of the data in allocated alternate blocks, saving of data before issuing this command and restoring of data after this command is executed are the responsibility of the INIT.
