Does Not Detect BD After Loading

Michael Kitchen

I’m using version 9.4.7.7 (currently the latest I believe). Even though it detects that an optical drive is present, according to the ‘Settings…’ window, it doesn’t even recognize the make and model of the drive let alone that a disc is loaded.

I’ve searched the forum here and the wider internet and found no other reports of this behaviour so I suspect it’s something that I’ve recently done to my WIndows 11 Pro (25H2) system. Hwever, I’m running out of ideas as to the cause. Windows explorer and other programs see discs loaded. Here’s a snapshot of the hardware manager.

Any ideas anyone?
TIA,
Michael

Just adding a snapshot of what Explorer sees.

Tried agian this morning. Loaded the BD into the drive and started Passkey which started up and logged in with my account OK. Here’re the last entries from the log.

Yesterday I tried uninstalling and reinstalling, both with and without saved configuration settings. Neither changed the behaviour.

It seems that passkey is not reacting to the presence of a disc in the drive. This appears to be only recent behaviour. I last successfully saved disc images just last month. Here’re the log entries from the last successful image save and the entries from yesterday when I first started seeing this issue.

Just tried something I’d overlooked. From “Troubleshooting 101”, restart Windows. 🙄 Didn’t fix the issue but did give me some more information. The optical drive (drive E🙂 was no longer visible to the system. Checking Device Manager, I saw the following.

So under the ‘Driver Details’ button in the ‘Driver’ tab I saw this.

Is it possible that there’s a problem with the ‘dvdfab.sys’ driver which has inadvertantly disabled the drive?

Michael Kitchen

Apologies. Should have selected the ‘dvdfab.sys’ item to show its details.

Michael Kitchen

An update. It appears to be a ‘dvdfab.sys’ driver issue. After I again uninstalled passkey I was able to reinstate the optical drive’s visibility on the system. However, it required deleting (uninstalling) the drive entry in Device Manager and then doing a fresh hardware scan to reassociate the ASUS driver to the device. The troubleshooting continues… 😉

Mona

Thank you very much for providing such detailed information, including the log files and the steps you’ve already tried. This is extremely helpful for us to understand the issue.

Could you please try one more quick step? Run Passkey as an administrator:

Right-click the Passkey shortcut on your desktop or in the start menu.
Select “Run as administrator”.
Load a Blu-ray disc and check if the software detects it.

If the problem persists, please restart Passkey again, and then go to the Settings panel to disable BluPath to load the disc again to see the result.

Michael Kitchen

Thank you for your response. I had left the state of passkey as ‘uninstalled’ in order to preserve access to my optical drive. However, I’ve just reinstalled it, reauthorized it to run on my PC under my account and reapplied my settings. Next I first confirmed the issue was still present. It was so I tried your first suggestion, stopped and restarted it with elevated (‘admin’) privileges. At first there was no change to the behaviour so, via Device Manager, I deleted the entry for the optical disc and ran a hardware scan to reassociate the driver. This time it picked up the ASUS driver as expected but the drive was still visible and passkey began to scan the disc. It’s currently running a disc image copy which I expect will successfully complete.

If possible I would prefer that I could run passkey with non-elevated privileges going forward. Thanks for your help.
