Figure 3.8 Alternate block allocation by REASSIGN BLOCKS command

(2)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.

: n represents a logical data block number

: Defective sector

: Unused spare sector
