Ok so, for some reason, my computer is not recognizing that i have cdrom drives at all, except in the device manager where i get the standard corrupt or missing driver message. i download the drivers and they won't install bc it won't recognize the fact that i have that cdrom. i have recently used a program that creates virtual drives. could that be my problem? i am at a loss. any ideas would be appreciated.

Hello saint4hire...

It's very likely that when you created the virtual drives, they put hardware hooks (filters) on the optical drives.

Click Start, then Run, type regedit and click "Ok"

In the left pane, expand (click +) HKEY_LOCAL_MACHINE, then SYSTEM, then CurrentControlSet, then Control, then Class, and click on {4D36E965-E325-11CE-BFC1-08002BE10318}

In the right pane, are UpperFilters and/or LowerFilters listed?

In the left pane, right click on {4D36E965-E325-11CE-BFC1-08002BE10318} and choose "Export". Name this file oldfilters and save it to your desktop.
In the right pane, right click on LowerFilters and choose "Delete"...accept the change. Right click on UpperFilters and choose "Delete"...accept the change.

Close Registry Editor and reboot.

Drives come back?

Great!!

You can delete the file you saved to your desktop (oldfilters)....it's no longer needed.
