A Virtual CD Does Not Work

[Top]  [Previous]  [Next]

The procedure for creating a virtual CD is quite simple. Still, when you try to run an application from a virtual CD, it might not work. This is often the case when the source CD uses non-standard formatting. If you make a virtual CD and then find that it doesn't work, please observe the following:

Check to Virtual CDs page of the Settings to make sure the detailed CD analysis function is using the expanded mode. With this setting, Virtual CD searches the entire medium for potential problems and configures the optimum settings for creating the virtual CD.
Virtual CD tries to determine the best settings for creating a virtual CD from a given source. Sometimes, however, this does not work, and it may be advisable to experiment with the options available on the Settings page of the Image Wizard to try and make a viable virtual CD.
If a Quick Copy file was used, switch this function off. If a Quick Copy file contains incorrect data, the problems are propagated, since the data is not read again.
Many CD applications require that the CD be loaded in a drive with the same drive letter that was used when the application was installed. If the application was installed and operated from a physical CD drive, try inserting the virtual CD in the same physical drive.
Some CD applications look for their CD in the first CD drive; i.e., the CD drive with the letter closest to the beginning of the alphabet. In such cases, inserting the virtual CD in the first physical CD drive might solve the problem.
Another possible solution is to try using a different physical drive for the source CD when making the virtual CD, since some drives cannot read all of the data on a CD.
Copying encrypted video media (such as CSS-protected movies) is prohibited by law. This is why Virtual CD does not support this encryption technique.



Always remove the CD-ROM from the physical drive before trying to run an application. Otherwise, you might not be able to tell whether the application is using the physical CD or the virtual CD.



Use the Comparison Wizard to determine whether the virtual CD contains the same data as the physical CD.



When a source CD is read, the results depend to a great extent on the features of the drive containing the CD – especially in the case of CDs with special formats. In particular, not all CD drives can read data pertaining to CD geometry. If you are not able to make a virtual CD from a particular source CD on your computer, ask other people you know whether they have made a virtual CD from the same source CD. If so, perhaps you can obtain a Quick Copy file, which you can use to make the virtual CD on your computer regardless of the capabilities of your physical CD drive.
