In DEVICE RESET on ATAPI, the command description says that the command returns a diagnostic code when it returns. However, the state machines require that the device return a status that would not allow for a diagnostic result to be returned (or at least not all of the diagnostic results).

Would the people in T10 that use ATAPI (primarily the MMC group) say that the reality of the world is that a diagnostic code is or is not returned and what would be the long term preference about the diagnostic code?

Thanks!

P.s. As the editor of ATA8-APT, I'll be more than happy to spend a few minutes in Hilton Head covering this if the MMC group feels that would be useful.
