Make sure you have 40-pin/80-wire type cable. Then use either the master/slave setup to connect. If that doesn't work, use the CS jumper instead for both. Its important to use the newer type of cable for best operation. if the problem still persists then the new CD drive just isn't capable to reside with the other CD drive or its really old. Quite frankly, you could have done better with a DVD drive that's CD and DVD capable even as a burner. Besides being newer and usually more open to the setup.
You didn't provide details of make and model#, etc. The details of your PC, OS, etc.. The provided info is generic so use as it pertains. Also, are there any bios updates, what do they do?
I recently installed a CD-RW drive in my computer. It was purchased from an electronics store as rebuilt. It's frankensteined. Before the CD-RW was installed, the CD-ROM drive worked fine. Now, after the install, it doesn't recognize and CD, including music CDs, games, or blank discs. I have uninstalled and reinstalled the drive in device management, I have physically re-installed both drives, swapping the cables (and the master/slave jumpers), I have checked the drive properties and they say the device is working properly. I have also checked to see if there is a hardware conflict. None. I booted in safe mode and the drive still won't read discs. I have also cleaned the drive with a CD drive cleaning disc. I'm thinking that my 40-pin cable connecting the CD-ROM drive may be faulty at the connection. Anybody have suggestions or ideas? Not wanting to replace the drive as I know it's good; it works in my other computer.
