Solve the conflict between virtual discs and dual optical drives

The author has always been a loyal user of "virtual CDs", which has been in use since version 5.0 and now version 7.0. However, recently, after installing "virtual optical disc" on a machine equipped with a dual optical drive, it was discovered that a physical optical drive was missing!

Hurry up and see all the difficult questions in the help file, but it doesn't even have a solution. Think about it again, maybe it is a problem with your own system? Also did not consider comprehensive, is a formatted format...

The system is finally installed, the first application installed down is the "virtual CD", after the restart is full of thought that the problem will be solved, can be seen, or There is a physical drive that I can't see! what on earth is this kind of happenings? Sitting in front of the computer and thinking about it, it is still puzzling.

Just thinking about giving up this software, I thought of the last move: try it on another dual optical drive machine! Just do it, immediately take the "virtual CD" software to another dual-drive machine, it is a hell of it, even two physical drives are still there. Observed that this machine's optical drive has a recorder, I think it is not a transmission mode problem, the default burner is the PIO4 mode. Go back to the problematic machine, open the CMOS setup program, find the Intergrated Penphetals, and change the "Auto" of the UDMA mode corresponding to the optical drive that you cannot see to "Disable". The long-lost drive after the restart is back.

Finally, the author called the customer service of this software and got a reply. It is true that this software was designed without considering the dual optical drive (UDMA mode), so there was a problem after the installation. I hope my experience will help everyone.

Xiaobian: Not to mention the specific method, here to talk to you about the ideas after the problem. When you encounter a problem that is difficult to judge, you may wish to try the last trick of the author, that is, to change the software or hardware in question to another normal computer. Simple logic: If it is not normal, that is the fault of this thing; normal? Basically you can determine the problem with other settings or components of your computer. Oh, this is also an exclusion method. Whoever makes the computer have so many inexplicable problems?
