Example Reassign: Block 16.

(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. The alternate block is allocated to unused spare sectors in the alternate cylinder.

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

Example Reassign: Block 16.

: n represents a logical data block number

: Defective sector

: Unused spare sector

Figure 3.8 Alternate block allocation by REASSIGN BLOCKS command

(3)Automatic alternate block allocation

•Automatic alternate block allocation at read operation

If the ARRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the IDD automatically executes the alternate block allocation and data duplication on the defective data block detected during the READ or READ EXTENDED command. This allocation method is the same as with the REASSIGN BLOCKS command (alternate sector treatment).
