cdrecord续刻失败的问题
使用cdrecord做续刻时，CD-RW的光盘可以续刻，DVD+RW和DVD-RW的光盘续刻均失败，打印信息我看到CD-RW使用的是TAO方式，而DVD都是使用的SAO方式。刻录执行的命令如下：
1. mkisofs -o /root/first.iso -Jrv /root/burn_1/
2. cdrecord -v driveropts=burnfree dev=1,0,0 -multi -data /root/first.iso
3. mkisofs -o /root/second.iso -Jrv -C 'cdrecord --dev=1,0,0 -msinfo' -M 1,0,0 /root/burn_2/
4. cdrecord -v driveropts=burnfree dev=1,0,0 -multi -data /root/second.iso
DVD-RW和DVD+RW均在第四步失败。
DVD-RW执行第二步，打印信息如下：cdrecord: No write mode specified.
cdrecord: Assuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
