Except for XAERROR.SCR, all test cases are expected to succeed and there should be no ERROR statements in the logs (unless a function such as Read UPC is not supported by the hardware). The log for XAERROR.SCR will have many ERROR statements but should have no Failure statements. Failure statements indicate that an expected error code was not received.

Test case logs need to be examined to verify that data is returned by certain CD-ROM commands as expected, particularly drive status commands. Not all returned data is automatically checked. Script comments will note what data is expected.
