dd if=/dev/dvd 一问
我把一个光盘放到光驱里面，使用
dd if=/dev/dvd of=my.iso
命令来生成 iso 文件，
报如下错误：
dd: 正在读入‘/dev/dvd’: 输入/输出错误
读入了 1322688+0 个块
输出了 1322688+0 个块
677216256 bytes transferred in 312.156140 seconds (2169479 bytes/sec)
而dmesg输出的错误如下：
hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1322688

hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }

这个光盘是我自己用 iso 文件刻录的，请问为什么会出现如上的错误？是不是我
的刻录有问题？
