This allows the Initiator to translate a LBA or physical sector address to the other format. The address to be
translated is passed to the Target with the SEND DIAGNOSTIC command and the results are returned to the Initiator
by the RECEIVE DIAGNOSTICS command. The Target will read the parameter list from the Initiator, and, if no errors
are detected in the parameter list, Good status will be returned. The data translation will be performed upon receipt
of the RECEIVE DIAGNOSTICS command.
