Data recovery operations from a CD or DVD drive with a damaged disc often benefit from a shorter timeout. Also, when retries are set to 0, an application is expecting errors and recovering them so do not print the error into the log. The number of expected errors can literally be in the hundreds of thousands which significantly slows data recovery. END
