CD/DVD drive is not detected or not shown in the my computer? I have 2 computers  

hi bro,
first check weather all the cables to your CD/DVD ROM drive are properly connected to both the sides, i.e. to motherboard and your drive. Then if it is connected properly then go to your system BOIS page before booting your system to OS (operating system) by pressing DEL button in your keyboard. In that go to booting priority options and select your CD ROM drive as secondary drive and before that check if you can see your drive is detected or not. If it is not detected then set your CD drive's small jumper setting to the back of the drive to slave.
Ok this must work, if not there is some hardware problem with your CD rom drive.

I hope this will help you.

This error is caused when you install something like EzCD, Deamon Tools, Roxio or something like that. You then go to get rid of it and it doesn't uninstall itself properly.

Windows has been told to use another file from another program to look at the CD unit through (sort of like a window if you like), and that program has now gone.

To resolve this behavior, follow these steps:
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

On the Edit menu, click Delete, and then click OK.
Quit Registry Editor.NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Computers are just funny that way sometimes. I dont believe its avirus. I believe its just a thing where maybe that particular computer was never intended to have 2 dvd drives. I actually just went out and bought a new one with a big hard drive and memory.

I think you may have to send it to the experts. Did you load in the software using the system CD? If so, it should have recognized the hardware. Open up your tower and see whether it is a connection problem. If all fails, go to the experts for advice and solution.

I sure wish I could help you with this. Have you tried to use a can of air and blow out the inside of the drive or try to clean it off with rubbing alcohol? That may very well fix it.

I had this same problem with my cdrom last night and I thought it might have been dirty since I have been listening to so many cds in it here lately. I tried to clean it with a cd but that didn't work. I still had windows media player installed on my system but it still wouldn't work. It worked good today, though. Of course, I scan my computer everyday for viruses so it could've been due to a virus. It's strange how it didn't work last night and it worked good today so there's no telling what went wrong.

you can either check the hardware connection in your computer or you can double check your latest software installed.

sometimes installation like this causes error in your hardware devices. machine are not perfect they have limitation and failures as well..

I can think of several things that I would do to see if I was able to correct the issue at hand. The first thing that I would do would be to check to see that all of the cables associated with the drive were properly connected. If you check and see that this is indeed the case, then I would look at the drivers. Perhaps I would reinstall them and see if they would make the drive function correctly. If neither of these things work, then I think it is time to see if a professional would be able to help me.

here is the solution,
you need to delete the upper and lower filters in the registry
click on start->run->regedit
press enter
(before you start take a backup of your registry by selecting file->export)
next hit ctrl+f and in the search dialogue box, type "upperfilter" and hit enter. now delete each upper filter you come across, do the same for lower filters too.
restart the pc
your optical drives will be visible again
