How to Troubleshoot Unreadable DVD/CD Drive

Unreadable DVD/CD drive

While I was trying to install a software on Windows 8.1, an error occurred which eventually affected a hardware component of my PC.

The DVD/CD ROM became unreadable; it was automatically disabled from reading DVD and CD devices.

The error message reads — Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly, or damaged, or that might be malicious software from an unknown source. (Code 52)

If you are in this same situation, then pay attention. The error message signifies Windows incompatibility with the software you are trying to forcibly install on Windows Operating System which led to the error. Windows could not recognize the publishing certificate or digital signature of that software. And as such, it is a security threat to Widows OS.

This sudden interruption is, however, a good security measure to protect your computer system against malicious softwares that can corrupt or compromise the health of your system.

Hence, the DVD/CD ROM is needed to be disabled or practically unreadable for loading of DVD or CD, preventing the corruption of your PC.

Temporarily, you will be unable to install any software, play music or watch movies via the DVD drive until the bug is resolved.


  1. Go to your BIOS settings to re-enable the DVD/CD drive or
  2. In your PC control panel, navigate to device manager and enable the DVD/CD ROM again. If the drive is still unreadable, then try to update the driver of your device and see the next line of action.
  3. If the options above is not helping, go back to the control panel to fix the error. Click on the troubleshooting icon, click hardware and sound, click hardware and device to initiate the dialogue box for diagnostic scanning. The error should be resolved.
  4. However, if the steps above did not work like my own case, there is only one option to solving the problem: download Microsoft ‘Troubleshooting Pack Cabinet’ to diagnose and automatically fix the error. You can get it from this link here.
  5. Once it is downloaded, run the software like any other program and it will bring a dialogue box to initiate the diagnostic process. From there, follow subsequent instructions and click on your DVD drive to fix the stubborn error.

How to troubleshoot DVD drive error

The diagnostic process of step 3 and step 4 is the same, but the internal troubleshooting process in the control panel could not rectify the problem. And that is why it is important to download the independent software that was specially made for this purpose by Microsoft. You only need to run it and it will do its job, no need of installation.

At present, this diagnostic cabinet is compatible with Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista, Windows 8, Windows 8.1, but Windows 10 is out of the picture.

On a final note, the Windows Operating System is automatically programmed to protect your system against this unauthorized intrusion. It can affect not only the DVD/CD drive, but other hardware ports like the USB which helps to transfer files from external devices to your computer system.
