我的系统是Fedora 8，先装的Windows XP(这个时候XP是有CDRW的),然后装的Fedora 8，装完之后第一次进入系统，打开菜单->位置->计算机,显示有CDRW,这时可以用，然后重启回到Windows XP,这时CDRW没有了，在XP的设备里多了一个未知设备，重新安装驱动 or 卸载设备 or 扫描硬件改动 or修复Windows安装都无法找到CDRW（这时回到Fedora里面，CDRW也没有了）；然后我格式化Windows XP所在盘符,全新安装XP后CDRW又找到了，然后我安GRUB,回到之前Fedora,这时CDRW也可以找到，这时在/dev/下有sr0,scd0,cdrw等设备，然后试着读盘，成功！然后我又回到Windows XP,这时在XP下又找不到CDRW了，最后又进入Fedora，这是也没有CDRW了，试着ls -l /dev/cd* 或者 ls -l /dev/sr* ，都提示ls: 无法访问 /dev/sr*: 没有那个文件或目录，附件是我的dmesg,想请教大家是什么原因照成这种结果的,谢谢了！
