Recently I had gotten a virus, and the only conclusion I could think of was to completely restart the computer; deleting everything, and having a back-up hard drive. Well, after GETTING back with my computer, and re-installing everything, my disc drive no longer was recognized, so if I were to put in a CD it would sound like it was loading, but it wouldn't show up as being loaded on my computer. I then LOOKED on My Computer file, and noticed that my disc drive didn't even show up as being there.
I've tried finding it on installed hardware, which it wasn't. I have no idea what to do now.  What make/model PC is it?It's a Toshiba. Model Satellite A205. LOL how did I guess?

I had this same problem a few weeks ago - my CD/DVD drive worked when it wanted to, basically. I checked online in every possible site available, and found out that it is a common problem with Toshiba laptops. I called Toshiba, they suggested things that I had already tried, and eventually came to the conclusion that a reformat was probably the only option to get rid of it.

So, here are a few things that I did to try and solve it, before even THINKING of a reformat:

Do you have iTunes installed?
If yes,
- Press the Start button and in the SEARCH bar at the bottom of the Start menu type "regedit”. Press enter.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318} (The first value of this entry should read "CD/DVD Drive").

Now once you have found the CD/DVD drives key in the right panel there should be "UpperFilter" and "LowerFilter". Right click each of these and select Delete.. Once you have deleted these close the registry editor and re-boot. Please, if you are unsure about anything, ask before doing it.

Did you try a system restore?

If neither of those options solve the problem, then...
- Start in safe mode using the F8 key method.
- Go to Start search. Type "device manager" and press enter.
- Check under CD/DVD Drives for SOMETHING starting with "TssT CORP".
- If you find it, right click and select Uninstall.
- Once uninstalled, reboot the PC into normal mode.
- When finished starting up, the computer should automatically install the device drivers for the disc drive again.


Any luck?Yes! Thank you so much for your help!  Great. I assume the problem is fixed?
