Command Specifications
256 C141-C013
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
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
(Section 4.4.2).
(3) Logical unit Self-Test
When "0" is specified in the "SelfTest" bit and the values other than zero is
specified in the "SELF-TEST Code" field in CDB, the HDD executes the Self-
Test specified in CDB. In this case, the INIT can read the executed results (page
code= x10 : Self-Test Result Log Page) by the LOG SENSE command.
The specified values in "PF" bit, "DevOffL" bit and "UnitOffL" bit in CDB are
ignored.
The "Parameter List length" field shall contain zero. If the value other than zero
is specified in this field, this command is terminated with a CHECK CONDITION
status (ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00]).
The "SELF-TEST Code" field specifies the type of executing Self-Test by this
command, as Table 4.55.
