Alternate block allocation by REASSIGN BLOCKS command

When the REASSIGN BLOCKS command is specified, the alternate block is allocated to the
defective logical data block specified by the initiator by means of alternate sector treatment. If
there are unused spare sectors in the same cylinder as the specified defective logical data
block, the alternate block is allocated to these unused spare sectors. However, the alternate
block is allocated to unused spare sectors in the alternate cylinder when all spare sectors in the
cylinder are used up.

Figure 3.8 is examples of the alternate block allocation by the REASSIGN BLOCKS
command.
