DVD烧录有什么问题？

Question

我已经有一段时间没有烧DVD了，今天我需要烧掉3张来自3个不同的iso文件的DVD。两个非常小的(几Kb)和一个非常大(8G，双层)。在使用K3b的两个不同的kubuntu系统上，它们在几秒钟内就失败了。小的有未指定的I/O错误，大的是：

Burned media
DVD+R Dual Layer

这是我最后一张双层DVD..。

也许我应该从dmesg中添加以下内容：

Answer 1

异常掩码0x0 SAct 0x0 SErr 0x0动作0x6已冻结

这表明SATA与驱动器的连接出现了硬件问题。

传统上，人们建议检查电缆和电力供应。但是我在网上看到了一些痕迹，坏的其他硬件(e.g.network)会导致这样的情况：https://bbs.archlinux.org/viewtopic.php?pid=1052099#p1052099。

(向Google输入上述错误信息，可以看到许多关于原因的不同报告，并有不同的理论。)

祝你今天愉快:)
