RECEIVE DIAGNOSTIC RESULTS requests error analysis data be sent to the initiator after completion of a SEND
DIAGNOSTIC command.
Allocation Length
: This field specifies the number of bytes that the initiator has allocated for returned diagnostic
data. An Allocation Length of ZERO means that no diagnostic data will be transferred. Any other value indicates the
maximum number of bytes that will be transferred.
If the SEND DIAGNOSTIC had the PF bit set, the drive returns four bytes of header data as will as eight bytes of the
diagnostic result. If the PF bit was not set, the drive returns only the eight bytes of the diagnostic result.
The drive terminates the DATA IN phase when Allocation Length bytes have been transferred or when all the
available diagnostic data (four or eight bytes depending on the PF bit) have been transferred to the initiator,
whichever, is less.
If the drive returns a CHECK CONDITION status with the HARDWARE ERROR Sense Key and an Additional Sense
Code of DIAGNOSTIC FAILURE set on completion of a SEND DIAGNOSTIC, then the Host should issue a
RECEIVE DIAGNOSTIC RESULTS command to receive the eight bytes of data indicating the actual failure and the
Most Suspect Unit (MSU).
If the Host issued a SEND DIAGNOSTIC with the PF bit set and a page Code of ZERO, the drive returns which
pages it supports in the following format:

If the Host issued a SEND DIAGNOSTIC with the PF bit set and a Page Code of 81h, the drive returns the following
