3.4.15 Receive Diagnostic Results command (1C
When the drive receives the Receive Diagnostics command after power-
up or after a Send Diagnostic command with PF=0, it sends eight
diagnostic data bytes to the initiator. The initiator sends the Receive
Diagnostic Results command after the drive completes the Send Diag-
nostic command. The page length is describe in the Send Diagnostics
command. The most recent Send Diagnostic command determines the
data returned by the Receive Diagnostic Results command.
