This command transfers data (response data) which show the results of executing the SEND DIAGNOSTIC command from the HDD to the INIT. The format and content of response data are determined by the parameter list (page code) specified by the INIT in the SEND DIAGNOSTIC command.

The "Transfer byte length" field in the CDB shows the maximum number of bytes of response data that can be received by the INIT by this command. The HDD transfers the number of bytes of data specified by this field or all the bytes of the effective response data, whichever is smaller in length. Also, when zero is specified in this field, this command is terminated without anything being transferred.

Exercise caution in the following points when using this command.

1.In order to avoid damage to the results of SEND DIAGNOSTIC command execution (response data) from a command issued by another INIT during the interval until this command is issued, either this command should be executed after the HDD is reserved.

2.Response data are valid only when "0" is specified in the "SelfTest (self test)" bit and after a SEND DIAGNOSTIC command which specifies a specific operation in the parameter list is executed, with the HDD transferring response data showing the execution results of the latest SEND DIAGNOSTIC command. Also, even if this command is executed, the response data in not cleared, and remains valid until the next SEND DIAGNOSTIC command is executed.

3.If this command is issued when valid response data do not exist, the HDD transfers a maximum of 4 bytes of X '00' data to the INIT.

Table 4.56 lists the format of response data transferred to the INIT from the HDD by this command. The response data are configured from a 4-byte "Page header" and the "Page parameters" which follow it.
