(2)Issuing the FORMAT UNIT command

Issue the FORMAT UNIT command and initialize the entire disk media surface.

In this FORMAT UNIT command, the entire disk media surface is initialized using the P List, then after initialization, the data blocks are verified. If any defective blocks are detected in the Verify operation, alternate blocks are allocated for those data blocks. Also, the defect position information for only the defective data blocks detected in the Verify operation is recorded in the G List.

The contents which need to be specified at this time are as follows.

a.CDB specification

Specify "0" in the "FmtData" bit and the "CmpLst" and "000" in the "Defect List Format" field in the CDB.

b.FORMAT parameters

If the items values in the previous item are specified in the CDB, the Format parameter is not necessary.

6.2.2Re-initialization

The INIT can reinitialize the disk drive after it has been operated using the FORMAT UNIT command.

Note:

If it is necessary after reinitialization to restore the data that were stored on the disk media, it is necessary to save the data before executing reinitialization, then execute data restore using system software after reinitialization.

The INIT can change the size of the spare sector area and its location as well as the number of logical data blocks before reinitialization. The recommended procedure for reinitialization is shown below. However, in cases where the logical data block length is changed, the initialization procedure described in Section 6.2.1 must be followed during installation.

(1)MODE SELECT command

If the logical data block count (size of the User Space) or the size of the spare sector area and its location are changed, issue the MODE SELECT EXTENDED command and specify the disk media format attributes. The parameter specification method is the same as in the case of initialization processing during installation, described in Section 6.2.1. If the same format attributes as at present will continue to be used, it is not necessary to issue the MODE SELECT EXTENDED command.
