I have XP Mediacenter 2005. When I click on the media center, I get the error message "ehExtHost.exe - No disk" window with the error message " There is no disk in the drive. Please insert a disk into drive\Device\Harddisk1\DR3" and the media center works fine. I cannot cancel , Tryagain, or continue. The window stays. Once I close the media center, I can cancel the error message window. I reinstalled the XP, but I still get the error message. How can I get rid off this?
