I am running Windows xp and I have recently begun to get an error message box appearing. In the header it says- 5b4:qttask.exe-No Disk In the main body of the message- "There is no disk in the drive. Please insert a disk into drive\Device\Harddisk3\DR6" Then the three options, Cancel, Try Again and Continue. Selecting Cance or Continue usually gets rid of it but it is very annoying. Can anyione explain what is causing this and how I can stop it please.
