I have installed Windows 7 on my computer and all the things are running well with that. Problem is that after installation of Windows 7, it is not able to detect blank disks. There is no problem when used with the CD previously written. Can you guess that what can be the reason for this problem? I know that my DVD drive is not having any fault because this was working well with my earlier operating system (Windows XP) and started with this problem only after the installation of the Windows 7 so there is surely something wrong with the OS. Either with my installation or may be some settings. I really canít guess that what the problem is. Can somebody over here guess a ny reason for this. If yes then please let me know that. I will be thankful for all the replies for this.
