Reassign Blocks (07) - Fujitsu MAX3073NC - SCSI,80, Dell DC961,Hard Drive Scsi Logical Interface Specifications

Note 1) ddd:
Note 2) The D List is not transferred from the INIT.
Note 3) If the data block length is changed and the disk media is initialized, the INIT cannot specify a
combination defect processing method.
Note 4) When this combination of defect processing methods is specified, the IDD performs verification
of the data blocks after initialization and creates the C List. In other combination defect processing
methods, the INIT can clearly specify whether the verification operation is prohibited or permitted
by the DCRT flag of the Format parameter.

This command allocates alternate data blocks for defective data blocks specified in the "Defect Data" list
transferred form the INIT.
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.
