$ cdrecord /dev/dvdrw /data/ISO/SWAN-Mail-2009.iso wodim: No write mode specified. wodim: Asuming -tao mode. wodim: Future versions of wodim may have different drive dependent defaults. wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.Device was not specified. Trying to find an appropriate drive... Looking for a DVD-R drive to store 4291.12 MiB...
