Address Format After Conversion

Logical or Physical Address

The “Address Format Before Conversion” field shows the format of the

address information specified in bytes 6 to 13. The IDD converts that

address information to the expression format specified in the “Address

Format After Conversion” field. the following codes can be specified as

Table 4.112.

0 0 0 Logical Block Address Format

1 0 0 Byte Distance from the Index Format

1 0 1 Physical Sector Address Format

The description format of the address information specified in bytes 6 to 13 is

the same as the description specification of the D List transferred from the

INIT by the FORMAT UNIT command. For details, see the description of

the FORMAT UNIT command (Section 4.3.1). furthermore, when the

logical block address format is specified, it must be described in bytes 6 to 9

and zero must be specified in the remaining byte positions.

When a logical data block address which does not exist (outside the range of

the MODE SELECT parameter) is specified in the logical block address

format, or when an area which cannot be allocated as User Space on the disk

drive (cylinders which physically do not exist) is specified in the “Byte

Distance from the Index” format or the “Physical Sector Address” format,

that command is terminated with a CHECK CONDITION status (ILLEGAL
