原因：一般我们把空白的光盘放进光驱时，发现读不了，或是没发现光驱有光盘，或是弹出“无法访问G:\,函数不正确”对话框等现象，原因有下面三种情况：
1、可能光驱坏了，或是数据线插得不好，
2、是光盘坏了，或是光盘的质量太差了，
3、是电脑的设置问题，因为我们一般装的都是ghostxp，很多功能精简或是关闭了，
如果是电脑设置问题，解决方法如下：
1）在系统下打开 "运行",输入services.msc，确定后弹出一个"服务"设置窗口，找到imapi cd-burning com services 项目，双击该项目，把启动类型由禁用改为自动，确定后重启系统。

2）打开"我的电脑"，---选择刻录机的驱动器属性，
在刻录的选项卡中，把"这个设备上启动cd录制"前打勾，
再重新放入空白光盘，就可以正常显示了。
