Fujitsu MAS3367, MAP3367, MAP3147, MAS3735, MAP3735 specifications Send Diagnostic 1D, SELF-TEST Code

Command Specifications

•When data are in the “Byte Distance from the Index Format,” when the P List is reported, multiple defect position information may be reported for a single sector, or 2 defective sectors may be reported as a single item of defect position information due to defects which extend across sector boundaries.

7.In defect data in the block address format, all the physical defect position information on the disk media cannot be described universally. For example, defect position information in areas without block addresses (spare sectors, or cylinders which are not being used as User Space or CE Space) cannot be described. The defect data in this format are provided in order to preserve continuity with previous specifications, but it is recommended that as much as possible, the INIT not use the “Block Address Format.”

This command executes self-diagnosis tests which the IDD is equipped to perform and operation specified in the parameter list transferred from the INIT.

(1)Self-diagnosis test

When the “SelfTest (self test)” bit is “1,” and “Self-Test Code” field is “000” in the CDB, this command specifies execution of the self-diagnosis test which the IDD is equipped to perform. At this time, the “PF (page format)” bit and the “Parameter list length” field in the CDB have no meaning and the values specified there are disregarded. Also, the “DevOfl (device off-line)” bit specifies whether or not operations which have an influence on the status of logical units other than the logical unit specified in this command during the self-diagnosis test, but in the IDD, there is only 1 logical unit that exists. Therefore, the specification in this bit has no meaning and the specified value is disregarded.

The INIT can specify the type of self-diagnosis test to be executed through the “UnitOfl (unit off- line)” bit. When “1” is specified in the “SelfTest (self test)” bit, the IDD executes a series of self- diagnosis tests in accordance with the combination with the “UnitOfl (unit off-line)” bit, as shown below.
