Figure 3.27 SEND DIAGNOSTIC Parameter: Logical/Physical Address Conversion
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 the "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 (item
3.3.1).
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 REQUEST [=5] / Invalid field in parameter list [=26-00]) and address
conversion is not executed.
Details of the address conversion algorithm executed when this parameter page is specified
and the data format, etc. of the conversion results reported to the INIT are explained in
RECEIVE DIAGNOSTIC RESULTS Command (item 3.4.2).
