Figure 138. REASSIGN BLOCKS

The REASSIGN BLOCKS command requests the drive to reassign a logical block to an available spare.
The REASSIGN BLOCKS command attempts to allocate spare blocks on a spare track. The logical block
address is transferred to the drive during the DATA OUT phase. One to four blocks may be specified for
relocation per REASSIGN BLOCKS command.
Reassignment is complete upon the completion of the REASSIGN BLOCKS command. At this time the
defective logical block address has been added to the grown (G-List) defect list.
Data contained at the logical block address being reassigned is preserved or filled with a constant pattern
depending on DRRT(Mode Page 0).
