[问题]IBM笔记本电脑的刻录光驱，如何在ubuntu下找到？

[tomshi]

请教一下：我用IBM T42本本上ubuntu6.10,系统mount光驱很正常，读光盘也没有问题。但才用刻录机刻录时，总是程序崩溃。后来用cdrecord命令查了一下，发现好像系统根本没有认出刻录光驱。命令执行情况如下：
~$cdrecord -scanbus

cdrecord: If you have unexpected problems, please try Linux-2.4 or Solaris.
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord:
cdrecord: For more information, install the cdrtools-doc
cdrecord: package and read /usr/share/doc/cdrecord/README.ATAPI.setup .

我想请问，应该如何设置，才能让系统自动可以识别本本上的这个刻录机？

下载个刻录软件GnomeBaker 或者 k3d试一试

[tomshi]

呵呵，怪我没说清楚。我已经安装了gnomebaker，但真正运行程序，总是在开始刻录的阶段程序崩溃。所以才想起用cdrecord来测试一下。

在我的T43上的输出，参考下

里面提示要root权限执行的。

cdrecord本来就是那些前端的底层。

[tomshi]

奇怪，我用$sudo cdrecord -scanbus命令，得到的结果还是如我上面贴出的一样，主要的问题似乎出在程序找不到“/dev/pg*”于是打不开scsi设备。
真正让我奇怪的是，为什么作为CDROM，光驱使用很正常，但作为CDR却完全没有反应。难道说是因为我安装了rox-filer，其中据有自动mount光驱的设定？可我把rox关了，情况也没有任何变化啊？看来完全从Server上自定义窗口和应用，绝对不是初学者可以尝试的。我折腾到现在，发现越折腾问题越多。我看来想重新安装desktop版本了。郁闷啊……

我从终端窗口直接运行gnomebaker，截取了到程序崩溃后的所有信息，如下：

段错误

看样子貌似gtk的某个模块没有安装正确。但我的系统已经用新立得更新了所有可以升级的包，上述报错信息我在google上查也没查出个所以然。请问，能否指点一下，究竟是怎么回事呢？

[tomshi]

经过再次测试，发现用gnomebaker直接刻录iso文件或者是flac格式的cue文件，程序必然崩溃，报错信息如上。但如果是刻录硬盘上的数据，直接刻录date CD，则完全没有问题，一切都运行正常。请问，这是否意味着gnomebaker在支持iso文件时，需要特殊的条件？

系统默认是把光驱做为只读cd和dvd光驱加载，要刻录就需要把光驱模拟成SCSI设备。
