Ops! I missed this change. BTW Do I understand correctly and ACTION_RETRY_WITH_BACKOFF_ALGO (or better returned SectorCount value) is not saved anywhere. So, every IO starts from:
ScsiDiskRead10, ACTION_NO_ACTION if (not Fail) done then repeat ScsiDiskRead10, ACTION_RETRY_WITH_BACKOFF_ALGO until (SectorCount<<1 || Success) So in case of DVD drive does not support large transfer would it be performance penalty on retries? I.e. if we know that drive does not support large transfer, why are we trying to submit unsupported IO every time?
